Abstract
Giant abdominopelvic tumors continue to present a diagnostic and therapeutic challenge for all surgeons despite all the advances in the world of imaging. Particularly, one of the most important challenges is to determine its probable origin for adequate surgical planning. Even though mostly all of these tumors are benign ovarian tumors, extraordinarily, malignant mural nodules may develop from the wall of these benign tumors, carrying an invariable unfavorable prognosis for the patient. This case highlights the importance of a correct diagnostic approach using ultrasound and abdominal computed tomography scans and confirming the diagnosis through a histopathologic examination. The treatment for these cases is surgical resection and posterior oncological treatment if needed. This case shows how timely treatment is one of the principal determinators of morbidity and mortality.

Abstract
Mesenteric cysts (MCs), rare entities of embryologic origin, predominantly affect the small bowel's mesentery. The clinical manifestations of MCs often lack specificity, which complicates diagnosis. Given their rarity, detailed reporting of MC cases is essential to enhance understanding and improve treatment strategies. We present a case of a 45-year-old male who presented to the emergency department with a one-month history of abdominal pain in the umbilical region, postprandial fullness, progressive decrease in food intake, 12 kg weight loss, and increased abdominal girth. Computed tomography (CT) imaging revealed a well-defined mass in the jejunoileal area. During the exploratory laparotomy, we identified and excised a fibrotic mass on the mesentery of the ileal jejunum, which was not adherent to the intestines. We discharged the patient with no complications following an uneventful four-day observational period. Histopathological examination, including immunohistochemical staining, confirmed the lesion as a non-pancreatic mesenteric pseudocyst. On the follow-up visit, the patient reported no complications. This case report underscores the solitary, multilocular nature of the jejunoileal MC, distinct for its serosanguineous fluid content. In conclusion, this case highlights the diagnostic challenge of MCs and illustrates the potential for successful management with a timely and multidisciplinary approach.

Mesenteric Cyst: A Rare Entity. Cureus 2023; 15:e48963. [PMID: 38111392 PMCID: PMC10726100 DOI: 10.7759/cureus.48963] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Accepted: 11/16/2023] [Indexed: 12/20/2023] Open
Abstract
Mesenteric cysts are rare entities that are challenging to diagnose and treat because of their variable presentation and histological characteristics. They have been majorly classified into six groups, out of which, the chylo-lymphatic type is the most common. Their etiology remains poorly understood but is usually linked to lymphatic pathologies. They are thin-walled cysts, present in the mesentery of the gastrointestinal tract. They can mimic multiple other cysts; hence, their timely diagnosis is of utmost importance. Imaging techniques aid in the preoperative diagnosis along with a thorough physical exam. The mainstay of treatment is surgical excision of the cyst, which is essential to prevent the recurrence of malignant transformation; the usual method of removal is laparoscopy. Alternative treatments are aspiration and marsupialization, which are only utilised for specific cases. The recurrence rate is usually low after total excision, but follow-ups are recommended for early detection of recurrence. This case study highlights the significance of prompt diagnosis and proper management of mesenteric cysts.

Abstract
Adrenal cysts are rare lesions that make up 4% of all adrenal masses. They are often found incidentally during imaging or surgery and can vary in symptoms depending on their size and location; with cysts < 10 cm often being asymptomatic. These cysts are more common in adults in their 30s or 60s and can be divided into four histological subtypes, with epithelial cysts being less common. We present a case of a 17-year-old female who experienced recurrent right flank pain for a year. Ultrasonography revealed a cystic mass on the right kidney, and computerized tomography showed a well-defined suprarenal cyst measuring ~8 cm misdiagnosed as mesenteric cyst. However, during laparoscopy, an adrenal cyst was discovered, which was excised along with the right adrenal gland. Histopathology confirmed the diagnosis of an epithelial adrenal cyst. This case highlights the occurrence of adrenal cysts in younger individuals and the uncertainty of preoperative diagnosis.

Abstract
Ganglioneuroma is a rare, benign, well-differentiated neurogenic tumor most commonly located in the posterior mediastinum or retroperitoneum. Giant ganglioneuromas are even less common; this is only the 19th reported case in literature to date. We present a case of a giant retroperitoneal ganglioneuroma in a five-year-old child, which on imaging mimicked a mesenteric cyst and posed various challenges in its management. Histopathology later confirmed our misdiagnosis and revealed the tumor to be a ganglioneuroma. This unique case serves as a lesson for clinicians to not operate before receiving histopathological confirmation of their diagnosis.

Abstract
UNLABELLED Lymphatic malformations (LM) refer to very rare hamartomatous benign lymphatic ectasias with an incidence of 1:250 000. They almost involve children more than adults, and among them, infants under one age are mostly affected. Macrocytic LM is found to be more than 2 cm in diameter or 2×2 cm2 in volume. The proper treatment for mesenteric LM is complete surgical excision unless there is vital structure involvement. CASE PRESENTATION The authors report a mesenteric macrocytic LM in a 2-year-old girl complaining of vague abdominal discomfort and persistent vomiting in which ultrasonography revealed a cystic masse with seromucous components. She then underwent exploratory laparotomy. The operation and the follow-up duration were uneventful. DISCUSSION LMs are rare benign lesions of vascular origin with lymphatic differentiation, according to the latest International Society for the Study of Vascular Anomalies (ISSVA 2018). Under light microscopy, these malformations are characterized by their thin-walled endothelium and lymphatic tissue.These mobile lesions are incidentally found or appear with intestinal obstruction or acute abdomen scenarios. CONCLUSION Although benign, the LMs have the potential for invasion and recurrence. Thus, the examiner physician must keep such intra-abdominal lesions in mind.

Abstract
Chylolymphatic cysts are an extremely rare variant of mesenteric cysts and account for 7.3% of all abdominal cysts. They can develop anywhere along the mesentery of the gastrointestinal tract and present in a wide range of symptoms. A 46-year-old male presented with mild abdominal pain and intermittent claudication in his right leg for the last 2 months and a history of a retroperitoneal resection of a simple abdominal cyst 5 years ago. Abdominal ultrasound and computerized tomography showed a fluid-filled cystic lesion measuring 17 × 11 × 10 cm in the right retroperitoneum. The cyst was surgically excised, and the histopathological examination was consistent with the chylolymphatic cyst. On a 1-year follow-up, the patient is recovered with no recurrence observed. Our report presents a case of a giant retroperitoneal chylolymphatic cyst with uncommon presenting symptoms and a rare etiology.

Abstract
Mesenteric cysts are uncommon intra-abdominal lesions that account for only one in every 100 000 adult hospitalizations. Their diagnosis is based on a comprehensive clinical examination as well as radiological modalities such as ultrasonography and computed tomography (CT) scans, and it is usually a clinical challenge because of non-specific symptoms. We present our first case of a 51-year-old man with a simple mesenteric cyst accompanying acute appendicitis diagnosed by CT scan of the abdomen and treated by exploratory laparotomy, complete enucleation of the cyst and appendectomy with a 10 month follow-up without complications or recurrence. This type of presentation has not been thoroughly investigated, with only two children reported during our literature review. Even if there is a high level of suspicion, a CT scan is required for confirmation.

Abstract
INTRODUCTION Mesenteric cysts are rare intra-abdominal tumours often found incidentally on imaging studies or during surgery. The clinical presentation is various with most subjects being asymptomatic, but complications can occur such as torsion, rupture, hemorrhage or obstruction of nearby structures. The etiology of mesenteric cysts remains uncertain. Complete surgical resection is preferred, although there are no specific guidelines concerning optimal treatment strategy. CASE REPORT We present a 61-year-old male with type 2 diabetes mellitus who underwent a routine abdominal ultrasound examination which accidentally uncovered a large mass. The patient had no complaints nor any physical discomfort. Magnetic resonance imaging and computed tomography revealed a giant thin-walled cyst with multiple septa spanning 24 × 24 cm2 originating from the mesentery. The primary differential diagnosis included a mesenteric cyst, a hydatid cyst due to echinococcus or malignancy. After multidisciplinary team approach, open surgical exploration was preferred. Surgical drainage and cyst sac resection were performed without any peri- or postoperative complications. Histopathology confirmed the presence of a large mesenteric cyst, probably caused post-traumatically. The patient has made a full recovery. CONCLUSION Mesenteric cysts can develop asymptomatically and reach enormous proportions. They are often found accidentally. Imaging studies aid in the differential diagnosis, but histopathology remains the diagnostic gold standard. Surgical resection prevails compared to a conservative approach due to the risk of complications. The choice between open or laparoscopic surgery should be determined based on the perioperative risk.

Abstract
Chylolymphatic cyst, variant of mesenteric cyst, is a rare entity. Clinical presentation and radiological features are not characteristic, so diagnosis can be made finally on histopathology. We report an extremely rare case of giant chylolymphatic cyst measuring >15 cm. A 2-year-old female presented with abdominal pain and vomiting. On examination, a ill-defined and firm mass was palpable just below umbilicus. Positron emission tomography-computed tomography scan revealed a large ill-defined lesion, which measured 16 × 13.2 × 6.7 cm in size and was seen in relation to the abdominal mesentery. Provisional diagnosis of mesenteric cyst was made. Laparotomy revealed multiple lymphatic cysts of variable size arising from the mesentery of proximal ileum. Histopathology examination confirmed the presence of a giant chylolymphatic cyst. Chylolymphatic cysts are rare entity and should be kept in mind while diagnosing a pediatric case of abdominal cysts.

Abstract
Mesenteric cysts are rare benign abdominal lesions that possess the risk of malignant transformation in 3% of reported cases. Most cysts are asymptomatic and diagnosed incidentally or during the management of their complications. In the majority of cases, they arise from the mesentery of the small bowel, followed by the mesocolon. We present a case report of a 20-year-old female with an abdominal mesenteric cyst.

Abstract
A mesenteric cyst is an uncommon ailment that can affect practically any abdominal quadrant in its presentation. They may turn up as an accidental discovery. Although there are a number of hypotheses explaining the genesis of these cysts, the exact etiology is unknown. A 70-year-old female patient came to see us complaining of abdominal pain for a month and had trouble passing stools for 15 days. Contrast-enhanced computed tomography was done for the patient, which revealed a heterogeneously enhancing mass lesion in the abdominal cavity. The patient was then taken for an exploratory laparotomy procedure. To make the procedure thorough and easy, intraoperative partial drainage of the cyst fluid was carried out. We were able to observe the margins of the mesenteric cyst more easily as the partial drainage was carried out. The partial drainage decreased the volume and size of the mesenteric cyst, reducing the pressure effect on the surrounding structures and allowing easy mobilization of the intraabdominal structures during intraoperative examinations. The partial drainage of the cystic fluid also made the dissection process safer. After releasing all adhesions, the cyst was delivered outside and sent for histopathological analysis. The histopathological reports confirmed it to be a mesenteric cyst. The aim of this article is to educate the readers and to make fellow surgeons well aware of this condition. This will not only help fellow clinicians in better diagnosis and treatment but also help in the reduction of the overall burden of the healthcare society by reducing mortality and morbidity.

Abstract
Mesenteric pseuodycst is a very rare benign childhood tumor, accounting for less than 1 out of 250,000 hospital admissions. We here report a case of giant mesenteric pseudocyst incidentally detected in a 11-year-old boy with acute appendicitis. He complained of persistent abdominal pain for the past 48 hours. He had a history of intermittent pain for several months. Physical examination showed fever and abdominal pain. Ultrasonography showed large peritoneal fluid related to peritonitis probably of appendicular origin. The patient underwent exploratory laparotomy revealing giant abdominal mesenteric cyst and acute appendicitis. Open resection of the cyst and appendectomy were performed. The diagnosis of uncomplicated acute appendicitis associated with mesenteric pseudocyst was made. Preoperative diagnosis of pseudomesenteric cysts is a clinical challenge. Knowledge is essential and suspicion should be maintained in patients with nonspecific symptoms.

Abstract
Mesenteric cysts are extremely rare intra-abdominal tumors. They usually present with an array of symptoms, usually non-specific, which leads to difficulty in diagnosing them. Occasionally these can present in the emergency as an acute abdomen. We report a rare presentation of a huge mesenteric cyst with gastric perforation, misdiagnosed clinically as obstructed inguinal hernia. A 50-year male presented with complaints of sudden severe pain in the abdomen along with swelling and pain in the right groin region with absolute constipation for the last 4 days. A clinical diagnosis of obstructed inguinal hernia was made. However, on radiological investigations, it was discovered as a giant intra-abdominal cyst herniating into the inguinal canal. On exploration, we were further surprised to find a concomitant gastric perforation. In this case report, we highlight that mesenteric cysts can present as acute abdomen and, very rarely, can be associated with an accompanying cause of surgical abdomen.

Abstract
Gossypiboma refers to foreign bodies left inside the body during surgery, such as sponges and gauze. These foreign bodies represent a significant cause of morbidity and mortality. A 57-year-old female presented to us with right upper abdominal pain. Her past history was non-contributory except for an open cholecystectomy 20 years previously. A physical examination revealed tenderness to palpation on the right of the abdomen, while the remaining examination was normal. An abdominal computed tomography (CT) and magnetic resonance imaging (MRI) scan revealed a well-defined calcified mass of 5 cm that was compatible with a mesenteric cyst. During surgery, the mass was found to be adherent to the mesocolon and to have invaded the colon wall. A right hemicolectomy and ileotransverse anastomosis was performed. The pathological mass was considered to be a gossypiboma that had been left behind during the earlier cholecystectomy. The body's reaction to the foreign body was seen to extend beyond the lamina propria and muscularis propria. Gossypiboma is an undesired and life-threatening but preventable surgical complication. This condition may present with non-specific findings and a clinical scenario that mimics various disorders, even after many years. A diagnosis of gossypiboma should be kept in mind for patients with a history of previous operations and undergoing surgery due to the suspicion of a mesenteric cyst.

Abstract
Any cystic lesion occurring in the mesentery which may or may not extend into the retroperitoneum is referred to as a mesenteric cyst; they have an infrequent incidence rate in the pediatric age group. Definitive etiology of the cystic lymphatic malformations is still not known but there are multiple hypotheses. A young male child presented with acute onset abdominal pain and palpable intra-abdominal mass and ultrasonography revealed presence of two lesions, one of them as an encysted turbid fluid collection in the right lumbar region and the other as a dilated, tortuous, intercalated structure. On CT, the first one was identified definitively as a mesenteric cyst while the other as a possible neoplastic mass in close proximity to the first one. Histopathology confirmed the diagnosis as a cystic lymphatic malformation of the mesenteric cyst. The limited awareness of its existence along with its usually asymptomatic nature, are the likely reasons that it still remains an elusive diagnosis. Based on our case we discuss, the use of a multi-modality approach towards diagnosing cystic malformation disorders and how the use of MRI is under-utilised when it could prove decisive.

Abstract
A lymphatic mesenteric cyst (LMC) is a rare clinical entity, of unclear etiopathogenesis, which can arise in the abdominal cavity or retroperitoneum without a clear origin. We describe a case of a 74-year-old male presenting with abdominal pain that was non-specific and non-responsive to medical therapy. Laboratory tests clinical examination were inconclusive while the abdominal computed tomography (CT) scan showed a cystic lesion of the ileal mesentery. We performed an open surgical excision of the lesion with the resolution of clinical symptoms. The lesion resulted to be an LMC at the histological examination. At the five-year CT scan follow-up, we did not record any recurrences. LMCs present without specific symptoms and imaging diagnostic techniques, such as ultrasound (US) or CT scan may define its features, location, or size. The preoperative diagnosis remains difficult, which is why the complete surgical excision is the gold standard treatment, aiming to prevent malignant transformation, complications, and recurrences.

Abstract
Abdominal lymphatic malformations in neonates require sophisticated management. In symptomatic cases, acute complications may necessitate immediate surgery. We present the case of a giant abdominal lymphatic malformation diagnosed in the 18th gestational week. Sonographic concerns about intestinal hypoperfusion in the 33rd week of gestation indicated caesarean section. Postnatal imaging confirmed a macrocystic lymphatic malformation occupying almost the complete abdominal cavity; the intestinal perfusion was normal. Clinical deterioration on Day 13 of life required laparotomy. Intraoperatively, the lymphatic mass was located in the ileocecal mesentery. Two major cysts showed recent hemorrhage explaining the onset of abdominal compartment syndrome. The malformation was completely removed. An ileocecal resection with an ileocolic anastomosis was performed. The postoperative course was uneventful. In neonates with abdominal lymphatic malformations, an onset of abdominal compartment syndrome requires surgical exploration. If feasible, the complete removal of the lesion represents a curative option.

Abstract
Mesenteric cysts are benign congenital cysts typically discovered incidentally during abdominal explorations for other reasons. When feasible, they should be excised to prevent recurrence, bowel obstruction or volvulus, and resulting complications. We present a unique case of an infant, diagnosed prenatally by ultrasound with possible bowel obstruction, found to have micro and macro chylous mesenteric cysts. Although initially asymptomatic with normal abdominal x-ray and discharged on day of life 2, the parents were taught how to recognize symptoms of bowel obstruction. He presented at 1 month with obstructive symptoms, was confirmed to have large mesenteric cystic structures on ultrasound, and was immediately taken to the operating room. Due to the extensive number of cysts and intimate involvement of the largest cyst with the superior mesenteric artery, he was treated with partial excision and observation since resection may have resulted in short gut syndrome. Given a prenatal ultrasound suggestive of mesenteric cysts, we recommend abdominal imaging at birth with close follow-up until the appropriate time for elective resection. When disease is extensive precluding full enucleation and resection, we advocate for enucleation in combination with unroofing of as many cysts as possible followed by postoperative surveillance ultrasounds and family counseling.

Abstract
RATIONALE Mesenteric cysts are benign gastrointestinal cystic lesions, with an incidence of <1/100 000. They usually develop in the small bowel mesentery, mesocolon (24%), retroperitoneum (14.5%), and very rarely originate from the sigmoid mesentery. Endometriomas represent a localized type of endometriosis and are usually within the ovary. Our case is unique because there are no reports in the literature of endometrial mesenteric cysts. PATIENT CONCERNS We present a case of a 29-year-old woman who underwent a routine gynecologic control. DIAGNOSIS Clinical examination and imaging identified 2 endometriomas on the left and posterior to the uterus. INTERVENTIONS The patient underwent exploratory laparoscopy. Unexpectedly, a 10 cm mesenteric cyst was identified; this was associated with adhesions in the left adnexal area and a left ovarian endometrioma. The classic surgical approach which was necessary identified the mesenteric cyst with cranial mesosigmoid and ileal adhesions, as well as distal adhesions which included the uterus, ileum, left ovarian endometrioma, left hydrosalpinx, left ureter, and rectum. The cyst was removed completely and a left adnexectomy was performed because of the presence of the endometrioma and adhesions. OUTCOMES The patient's outcome was favorable, with discharge at 72 hours after surgery. The histopathological report revealed that both the mesenteric and ovarian cysts were endometriomas. LESSONS Our case is unusual in that a mesenteric cyst was identified in a patient with no clinical symptoms. Furthermore, the histopathological examination revealed the endometriotic origin of the mesenteric cyst which has not previously been reported in the literature.

Abstract
A rare case of a jejunal mesenteric pseudocyst treated by robotic resection is reported. A 25-year-old woman was admitted to our hospital with intermittent abdominal discomfort which was exacerbated by strenuous physical activities. Physical examination revealed a fluctuant mass without tenderness. Contrast-enhanced computed tomography revealed a 4 cm-sized non-enhancing heterogeneous mass on a proximal small bowel loop mesentery. Based on the findings, a differential diagnosis of a gastrointestinal stromal tumor, hematoma, desmoid tumor, and mesenteric cyst was made. Robotic diagnostic laparoscopy was performed to obtain an accurate diagnosis and treatment. Exploration of the cavity revealed a 4 cm fairly mobile mass originating from the mesentery of the jejunum. Segmental resection of the jejunum and its mesentery, including the mass and extracorporeal anastomosis, was performed without any complications. Macroscopically, the mass was cystic and the lumen had grumous material. The final pathological diagnosis was a mesenteric pseudocyst. The patient had an uneventful postoperative course.

Intraductal tubulopapillary neoplasm (ITPN) of the pancreas with invasive cancer misdiagnosed as a mesenteric cyst for 12 years: a case report and literature review. INTERNATIONAL JOURNAL OF CLINICAL AND EXPERIMENTAL PATHOLOGY 2019; 12:1041-1046. [PMID: 31933917 PMCID: PMC6945180] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 12/23/2018] [Accepted: 01/22/2019] [Indexed: 06/10/2023]
Abstract
INTRODUCTION An intraductal tubulopapillary neoplasm (ITPN) depicts a distinct entity in the subgroup of premalignant epithelial tumors of the pancreas. Due to the rarity of ITPN, information regarding the disease is currently limited. We present herein a case of pancreatic ITPN with invasive cancer that was misdiagnosed as a mesenteric cyst during a 12-year follow-up period. CASE REPORT A 23-year-old female initially presented with an incidental asymptomatic 4-cm retroperitoneal cystic lesion in 2005. For 12 years of surveillance, the lesion remained largely unchanged in size (4-5 cm). In 2017, the cystic lesion was found to have grown to 9 cm. The pre-operative diagnosis was highly suggestive of a benign lesion. However, after total resection of the mass was performed, the final diagnosis was pancreatic ITPN with invasive cancer. The patient recovered uneventfully and is disease-free without recurrence at the time of this report (12 months post-surgery). CONCLUSION The clinicopathologic features of ITPN remain unclear due to its rarity, thus making diagnosis difficult. Clinicians should always consider the possibility of ITPN for cystic lesions located at the retroperitoneum near the tail of the pancreas. More data are needed to understand the disease's long-term outcome to identify clinical and radiological features that can be useful for its diagnosis.

Ultrasound and differential diagnosis of fetal abdominal cysts. Exp Ther Med 2016; 13:302-306. [PMID: 28123506 DOI: 10.3892/etm.2016.3948] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2015] [Accepted: 09/09/2016] [Indexed: 12/12/2022] Open
Abstract
The present study aimed to investigate the use of ultrasound and differential diagnosis to diagnose a fetal abdominal cyst. A retrospective analysis of 41 cases of fetal abdominal cyst, which included ovarian cysts, choledochal cysts, intestinal duplication and mesenteric cysts, was performed. Imaging characteristics of various types of cysts were summarized, compared and discussed. Among 41 fetal abdominal cyst cases, there were 21 cases of ovarian cysts, 11 cases of bile duct cyst, six cases of intestinal duplication and three cases of mesenteric cyst. Each type of fetal cyst had its own distinctive characteristics on abdominal ultrasound examination. Ovarian cysts were located at one side of the bladder, round-shaped and observed in female fetuses; choledochal cysts were located in the hilar, were oblong- or oval-shaped and connected to the bile duct; intestinal duplication was located in the middle of abdomen, close to the intestine, and presented as an intestinal wall-like structure; mesenteric cysts were round-shaped with thin tensionless wall, presented with multiple chambers, and were easily deformable on compression. The findings of the present study demonstrated that a comprehensive analysis of the association between the cyst and its adjacent location, shape, wall thickness, motility and other aspects of dynamic changes via ultrasonography may provide a differential diagnosis of different types of fetal abdominal cysts.

Abstract
Mesenteric cysts are benign cystic lesions. Here, we present the case of a patient with abdominal pain, which was diagnosed as mesenteric cyst. A 28-year-old male patient was admitted to the emergency department (ED) with abdominal pain and distention. Abdominal palpation revealed a smooth-surfaced mass palpable in the left upper quadrant. Ultrasonography depicted a hypoechoic heterogeneous mass-like structure with a size of 15 × 12 cm. Computerized tomography (CT) showed a well-defined cystic structure with a size of 12 × 12.5 cm near to the duodenum and pancreas. The patient was admitted, and the cystic structure was drained with a percutaneous drainage catheter; then, sclerotherapy was performed using ethyl alcohol with the aid of ultrasonography. The material was sent to the pathology lab and revealed negative results for malignant cell and mucin. The patient underwent a control CT with contrast, which revealed the catheter at the site of the operation and no cystic lesion after procedure. He was discharged 1 week after the procedure. Mesenteric cysts are extremely rare benign lesions of the abdomen, and emergency physicians must consider this disease in the differential diagnosis of abdominal pain. The percutaneous drainage technique performed on our patient is a safe technique for the treatment of selected patients.

Abstract
In February 2007, a 41-year-old Japanese male was admitted to our hospital with increasing upper abdominal pain. A contrast-enhanced computed tomography (CT) scan of the abdomen demonstrated a well-demarcated, hypodense cystic mass with a thickened wall in the mesocolon. The laboratory results were within normal limits, except for increased carcinoembryonic antigen, carbohydrate antigen 19-9, DUPAN-2 and SPAN-1. The patient was diagnosed as having a mesenteric malignant cyst, and during a laparotomy, a right hemicolectomy with mesenteric cystectomy was performed without rupture in March 2007. In the microscopic findings, there was a well-differentiated adenocarcinoma in the inner surface of the cyst and in the fibrous connective tissue of the hypertrophic cystic wall. The tumor cells were immunohistochemically reactive to cytokeratin (CK) 7, CK18 and CK20. No remnant of the malignancy was detected in the resected margin of the colon, cyst, liver or peritoneum nor was an uptake detected in an 18[F]-fluorodeoxyglucose positron emission tomography/CT examination of other organs. Finally, the malignancy was concluded to be a serous cystadenocarcinoma of the mesentery. Nineteen months after the operation, the patient died from peritonitis carcinomatosa due to a small intestine rupture. This report suggests mesenteric cystadenocarcinomas originating in the ovary, oviduct and intestinal mucosa, but these were ruled out in our patient. In this report, we discuss a case of the malignant transformation of a cyst into adenocarcinoma, which to our knowledge has never been previously reported in a male patient.

Abstract
INTRODUCTION Mesenteric pseudocyst is a term used to describe an abdominal cystic mass with an unknown abdominal origin. They are rare intra-abdominal masses, with a reported incidence of approximately 1 per 100,000 to 250,000 hospital admissions. Most cysts are benign and they may present differently, such as a disappearing mass or a mass that changes locations, thus posing a diagnostic challenge to the clinician. CASE REPORT We describe a case of a 29-year-old woman who presented with a 2-year history of feeling a large mass within her abdomen, which would then disappear for several days and would frequently change position and be felt in different quadrants of her abdomen. Computed tomography scan of the abdomen revealed a large cystic structure, and a computed tomography- guided biopsy was inconclusive. Diagnostic laparoscopic surgery revealed a firm mass arising from the jejunal mesentery; the patient underwent an en bloc resection. Histopathologic examination of the resected mass revealed a rare diagnosis of mesenteric pseudocyst. Mesenteric pseudocyst should be should be kept high on the list of differential diagnoses when a patient presents with a disappearing mass and/or an abdominal mass that changes location.

Abstract
Mesenteric cysts are rare abdominal tumours. They are found in the mesentery of small bowel (66%) and mesentery of large intestine (33%), usually in the right colon. Very few cases have been reported of tumours found in mesentery of descending colon, sigmoid or rectum. Mesenteric cysts do not show classical clinical findings and are detected incidentally during imaging due to absent or non-specific clinical presentation or during management of one of their complications. Ultrasonography (USG)/computed tomography (CT)/ magnetic resonance imaging (MRI) are used in diagnosing mesenteric cyst but they cannot determine the origin of cyst. Laparoscopy not only helps in diagnosing the site and origin of the mesenteric cyst but also has a therapeutic role. Laparoscopic treatment of mesenteric cyst is a safe, preferred method of treatment and is a less-invasive surgical technique. Here, we present an unusual case of mesenteric cyst arising from the sigmoid mesocolon treated by laparoscopic excision.

Abstract
BACKGROUND Congenital chylous ascites is a rare condition that constitutes a challenge for the physician. It is defined as the accumulation of chyle into the peritoneal cavity in infants younger than 3 months. This condition is often refractory to therapy and it is responsible for serious malnutrition and immunological deficiency because of the loss of proteins and lymphocytes. MATERIAL AND METHODS Four cases of congenital neonatal chylous ascites, were treated by our staff during the last two years. One case was treated conservatively and three with laparotomy. Two of them had intraabdominal cysts that were excised and one was treated with ligation of the left lumbar lymphatic trunk and cisterna chyli and the use of fibrin glue. RESULTS All four cases were treated successfully. On follow up tests no one showed recurrence of the ascites. All children, except the one that treated conservatively and also had other problems due to prematurity, are growing up normally. CONCLUSIONS Congenital chylous ascites is a complex condition. Its diagnostic evaluation is difficult and its therapy of long duration. Conservative treatment is in most cases the initial choice, but when it fails, exploratory laparotomy could provide a successful alternative.

Abstract
Mesenteric cysts are uncommon benign abdominal lesions with no classical clinical features. The preoperative diagnosis requires the common imaging modalities but the final diagnosis is established only during surgery or histological analysis. The treatment of choice is complete surgical excision. We report an 18-year-old female with a non-specific abdominal pain and discomfort since 3 weeks. Her CT scan showed a huge cystic swelling, which necessitated surgical exploration. Preoperatively, a giant cyst was encountered with displacement of bowel loops. The cyst was completely removed and histology report confirmed mesenteric cyst without evidence of malignancy.

Abstract
Intra-abdominal cysts and pseudocysts are rarely occurring lesions. Their incidence is reported to be 1 per 100 000-250 000 hospitalizations. The lesions' rarity and their mostly asymptomatic development causes troubles in early recognition and treatment. The patients' complaints are unspecific and mostly occur when the cysts are enlarged. Sometimes these entities may cause signs of peritoneal irritation and be the reason for immediate operation. It may happen in the event of cyst rupture, torsion, haemorrhages into the lesion or signs of compression of neighbouring structures. Many radiological methods are helpful in revealing intra-abdominal cysts. Unfortunately they cannot accurately distinguish the character of the lesion. The most common surgical procedure of treatment is excision during laparotomy. However, in some cases the laparoscopic approach can be equal to open surgery. This article presents a case of a young woman with a large intra-abdominal pseudocyst treated with laparoscopy.

Abstract
Lower abdominal pain of acute onset in young women with a negative pregnancy test is a frequent reason for referral to the general surgical team and the differential diagnoses include acute appendicitis, complicated ovarian cysts and pelvic inflammatory disease. Intestinal and mesenteric cystic disease is a rare entity and less than half of cases present acutely. We present a case of a 25-year-old woman who underwent diagnostic laparoscopy for acute lower abdominal pain and was diagnosed with a ruptured, infected mesenteric cyst.

Abstract
Mesenteric cysts are rare intra-abdominal masses, presenting with various clinical signs and symptoms. Mesenteric cysts presenting with a sudden onset of urinary retention is extremely rare. There are no cases reported in the English literature. Here, we report a very rare case of urinary retention, due to mesenteric cyst in a 19-year-old man. The patient presented with abdominal distention with a sudden onset of urinary retention. Ultrasonography and computed tomography scan of the abdomen revealed a huge cystic mass above the bladder that was completely separated from the kidney and bladder. The cyst was removed surgically. The patient experienced no urological difficulty after the surgery. Histological examination confirmed the diagnosis of a mesenteric cyst.

Abstract
BACKGROUND Laparoscopic management of mesenteric cysts during pregnancy has not been reported before. CASE REPORT A young woman with a mesenteric cyst associated with a crossed ectopic kidney, underwent laparoscopic excision of the cyst in the second trimester of pregnancy. The procedure was completed without complications, and the patient was discharged on the third postoperative day. Thereafter, the pregnancy progressed uneventfully, and she delivered a healthy baby at term. CONCLUSION Laparoscopic management of mesenteric cysts during pregnancy is feasible, safe, and less invasive than laparotomy when performed in select patients by experienced surgeons.
