Neonate with congenital pulmonary airway malformation concurrent with enteric duplication cyst: a case report of a rare anomaly

A congenital pulmonary airway malformation (CPAM) occurring concurrently with an enteric duplication cyst is a rare anomaly. Definitive management for both abnormalities is usually surgical resection. We present the uncommon case of a neonate with a CPAM and ileal duplication cyst, including pre-natal and post-natal workup. The patient was brought to the operating room for laparoscopic duplication cyst excision at 3 months of age. The patient returned to the operating room for a thoracoscopic right lower lobectomy at five months of age. This case presents a rare congenital anomaly with the concurrent presentation of a CPAM and enteric duplication cyst, with both being successfully excised minimally invasively.

Mediastinal Bronchogenic Cyst With Superior Vena Cava Syndrome: A Case Report

Bronchogenic cysts are rare in adults and often remain undetected until discovered incidentally on imaging or during a symptomatic investigation. The possibility of superior vena cava (SVC) compression due to a bronchogenic cyst arises in complex patient presentations. SVC syndrome poses several unique challenges due to the wide range of clinical symptoms and difficulty identifying the cause when symptoms first manifest. This case report examines a 39-year-old male who presented with symptoms resulting from SVC compression caused by a bronchogenic cyst, leading to SVC syndrome. We discuss the various imaging modalities used to assess the severity of the obstruction and the surgical interventions employed to alleviate the symptoms. A surgical intervention provides symptomatic relief and promises an excellent prognosis when performed without complications.

Spontaneous self-expulsion of an oesophageal duplication cyst

A case report of an oesophageal duplication cyst in an adult patient with chronic cough and presenting with a "coughed out lump". This is an unusual presentation highlighting the importance of considering congenital duplication cysts in patients with chronic cough and no obvious respiratory cause.

Unusual Presentation of an Ileal Duplication Cyst: A Case Report

Duplication cyst (DC) of the digestive tract is a rare embryological anomaly, presenting as a cystic formation that could be attached to any part of the digestive tract, it is a thin-walled structure made of two layers, an inner layer that is frequently lined by an alimentary epithelium, surrounded by a smooth muscle layer often shared with the adjacent digestive segment. DCs are most commonly located in the distal ileum; sometimes, they are associated with other visceral or skeletal anomalies. They are frequently discovered during childhood, following a bowel obstruction or abdominal pain. Here we report a rare case of an ileal DC lined by a pseudostratified and ciliated epithelium, discovered in an adult patient following intestinal obstruction syndrome.

Esophageal duplication cysts: a clinical practice review

Esophageal duplication represents one of the most common types of bronchopulmonary foregut malformations. These rare congenital anomalies occur secondary to embryological aberrations between the 4th and 8th weeks of gestation. In order to be classified as an esophageal cyst a mediastinal cyst must have a close proximity with the esophagus, be lined by alimentary (squamous epithelium) or tracheobronchial mucosa and covered by two smooth muscle layers. These rare anomalies are often asymptomatic during adulthood. However, they can cause symptoms in early childhood, generally during the first 2 years of life. Variations in location, size, presence or absence of heterotopic mucosa, will dictate the clinical presentation. Dysphagia, food impaction, persistent cough and chest pain are common clinical presentations. Imaging studies including esophagram, computed tomography (CT) and magnetic resonance imaging (MRI) can provide key findings to reach the diagnosis. Nonetheless, endoscopic evaluation, particularly endoscopic ultrasound (EUS) is the most valuable tool to determine whether this lesion is cystic versus solid and or if there are abnormal mucosal findings. Needle biopsies are controversial but can help with drainage and to rule out malignant transformation. Therapeutic options include endoluminal drainage. However, more definitive therapies include surgical excision. Open and minimally invasive (laparoscopic and thoracoscopic) techniques have been demonstrated to be safe and effective at completely removing these lesions. Recently, robotic-assisted resections have gained more attention with case reports and series reporting excellent outcomes.

Giant Brunner's gland hamartoma diagnosed via endoscopic mucosal resection: A case report

We report the case of a patient with a giant Brunner's gland hamartoma that was pathologically diagnosed by endoscopic mucosal resection. A 69‐year‐old woman presented with intermittent abdominal pain, and imaging revealed a smooth saccular submucosal tumor, 40 mm in diameter, on the anterior wall of the duodenal bulb. Brunner's gland and smooth muscle tissue were observed on endoscopic ultrasound‐guided fine‐needle aspiration biopsy, which resulted in the preoperative diagnosis of a duplication cyst. However, subsequent endoscopic mucosal resection established a final histopathological diagnosis of Brunner's gland hamartoma.

Duplication cyst and diverticulum of the stomach: A case report of an unusual association

Gastric duplication cysts are uncommon findings in adult patients. Accurate diagnosis of these cysts is difficult. Presenting symptoms are often non-specific, and complications are rare. We report an uncommon case of a non-communicating duplication cyst associated to a diverticula of the stomach in 38-year-old women.

Tubular Ileal Duplication Causing Perforative Peritonitis in an Adult: A Rare Presentation

Background  Enteric duplication cysts are a rare congenital abnormality that present more commonly in children than adults. Clinical presentation varies from vague abdominal pain, abdominal lump, iron deficiency anemia to intestinal obstruction due to intussusception or mass effect. We report a tubular ileal duplication in an adult male presenting with an acute abdomen due to perforative peritonitis.

Case  A 20-year-old male presented to the emergency department with complains of right lower abdominal pain. On clinical examination and ultrasound scan patient was suspected to have a complicated acute appendicitis (rupture). However, a computed tomography scan was suggestive of perforation in the distal ileum. Emergency exploratory laparotomy revealed a perforated isolated ileal tubular duplication.

[Endoscopic treatment of duodenal duplication cyst]

Duodenal duplication cyst (DDC) is a rare form of intestinal malformation (2-12% of all gastrointestinal duplications). There are many difficulties in diagnosis and management of DDC. We present a case of successful endoscopic transluminal treatment of DDC in a 30-year-old female. She complained of epigastric pain, nausea and vomiting, weight loss of 5 kg over the past 3 months. Laparoscopic cholecystectomy for gallstone disease was performed 18 months prior to admission. Examination revealed a cyst 52×60?35 mm in descending part of duodenum. There was a calculus inside the cyst. Transluminal endoscopic cyst fenestration was performed. Histological examination confirmed DDC. According to control duodenoscopy data, cyst was collapsed. The patient remains asymptomatic three months after surgery. DDC is a rare disease of gastrointestinal tract, which should be differentiated first with choledochocele Todani type III and intraluminal duodenal diverticulum. Endoscopic treatment may be an adequate alternative to traditional interventions in some cases.

Feline abdominal ultrasonography: What's normal? What's abnormal? The diseased gastrointestinal tract

PRACTICAL RELEVANCE

Abdominal ultrasound plays a vital role in the diagnostic work-up of many cats presenting to general and specialist practitioners. B-mode ultrasonography is likely the most widely used modality for imaging the gastrointestinal (GI) tract in cats and it can help in the diagnosis of GI masses, foreign bodies and disorders of the ileocaecocolic junction.

CLINICAL CHALLENGES

Despite ultrasonography being a commonly used modality, many practitioners are not comfortable performing an ultrasound examination or interpreting the resulting images. Even differentiating between normal variations and pathological changes can be challenging for all but the most experienced. For example, while for inflammatory conditions of the feline GI tract changes are frequently identified on ultrasound, there may occasionally be no changes to the appearance of the intestine; hence a 'normal' ultrasound does not exclude the possibility of inflammatory disease.

AIM

This review, part of an occasional series on feline abdominal ultrasonography, describes the appearance of a range of conditions that affect the feline GI tract; the normal GI tract is addressed in an accompanying article in this issue of JFMS. Aimed at general practitioners who wish to improve their knowledge and confidence in feline abdominal ultrasound, this review is accompanied by high-resolution images and videos available online as supplementary material.

EQUIPMENT

Ultrasound facilities are readily available to most practitioners, although use of ultrasonography as a diagnostic tool is highly dependent on operator experience.

Video-assisted thoracoscopic excision of esophageal duplication cyst in an adult

Esophageal duplication cysts are rarely encountered in adult patients. Complete cyst resection is achievable employing video-assisted thoracoscopic surgical techniques, with low morbidity and excellent cosmesis.

Caecal duplication cyst leading to intussusception in an adult

Colonic duplication cyst is an uncommon cause of intussusception in adults. We report a case of caecal duplication cyst in a 24-year-old adult with a 3-year history of recurrent abdominal pain mainly in the periumbilical region. CT and MRI of the abdomen showed a lesion suggesting an caecal duplication cyst within an intussuception. The patient underwent diagnostic laparoscopy and was found to have a caecal duplication cyst acting as a lead point for the intusseception for which laparoscopic-assisted resection was performed. The histological examination confirmed the presence of intestinal duplication cyst without any underlying malignancy.

Recurrent acute pancreatitis caused by duodenal duplication cyst in a young patient

Duodenal duplication cyst is a rare congenital anomaly that develops during the embryonic stage and could remain unknown until the adult age. Although often asymptomatic, duodenal duplication cysts can lead to various clinical scenarios with different degree of severity, from nonspecific abdominal pain up to cholestasis, intussusception or pancreatitis.

Intralingual Mucous Extravasation Cyst: An Uncommon Lingual Cyst

OBJECTIVE

We report a rare case of an intralingual ranula. The differential diagnosis, etiology, diagnostic features, and management are discussed.

CASE REPORT

An 18-year-old man presented with a mass that extended along the ventral surface of the tongue and up to the tip. The computed tomography scan clearly defined the extent of a cystic lesion. The pathologic diagnosis of an intralingual ranula was made.

CONCLUSION

Lingual cysts have a varied etiology. Diagnosis hinges on histological examination of the cyst wall. Conservative resection and histological examination is the standard of care.

Paraneoplastic Auto-immune Hemolytic Anemia: An Unusual Sequela of Enteric Duplication Cyst

Enteric duplication (ED) cysts are rare congenital anomalies of the alimentary canal that present in childhood. Although benign in most case, ED cysts have the potential to cause complications including a rare association with secondary carcinomas. Autoimmune hemolytic anemia presenting as a paraneoplastic syndrome secondary to solid tumors is an unusual phenomenon. Here we report a patient case with ED cyst described in association with intestinal adenocarcinoma and warm-auto immune hemolytic anemia, with resolution of the hemolysis upon its surgical resection.

Heterotopic Gastric Mucosa in a Duplication Cyst of the Common Hepatic Duct Mimicking Cholangiocarcinoma

Heterotopic gastric mucosa in biliary tract is a congenital anomaly that can prove significant clinical dilemmas. Here we report the case of a 28-year-old female patient presenting with jaundice, pruritus, and altered liver tests, with predominant cholestasis. Liver biopsy revealed histological changes suggesting large bile duct obstruction with advanced fibrosis. At imaging, common hepatic duct stricture due to an intraluminal enhancing mass was observed. Endoscopic retrograde cholangiopancreatography and upper echoendoscopy revealed a firm mass of the common hepatic duct with a complete obstruction, suspicious for cholangiocarcinoma. Fine-needle aspiration biopsy performed under echoendoscopic guidance revealed fundic type gastric mucosa. Despite histological result, radiological suspicion of malignancy together with advanced fibrosis prompted a segmental resection of biliary tract. At macroscopic examination, the common hepatic duct presented a focal pseudocystic appearance with a firm zone of subtotal stenosis. Histology revealed a duplication cyst lined by heterotopic fundic gastric mucosa. Heterotopic gastric mucosa of the biliary tract should be suspected in young patients without know risk factors for hepatobiliary malignancies. Imaging and careful histological examination are mandatory for optimal management. Liver fibrosis, secondary to chronic biliary obstruction may be a significant late complication.

Ruptured rectal duplication with urogenital abnormality: Unusual presentation

Rectal duplication (RD) accounts for 5% of alimentary tract duplication. A varied presentation and associated anomalies have been described in the literature. Antenatal rupture of the RD is very rare. We present an unusual case of a ruptured RD associated with urogenital abnormalities in newborn male. We are discussing diagnosis, embryology, management and literature review of ruptured RD.

Diseases mimicking intussusception: diagnostic dilemma

BACKGROUND

Intussusception is a common abdominal emergency in early childhood. The aim of this study was to describe the diseases mimicking intussusception and to discuss the causes and management of these conditions.

METHODS

Seven patients who were initially diagnosed as having intussusception on abdominal ultrasonography but who had a final diagnosis of diseases other than intussusception were reviewed retrospectively.

RESULTS

Two patients with ileocolic intussusception underwent ultrasonography-guided reduction with a hydrostatic method but the ultrasonographic findings persisted. At surgery, only edematous ileocecal valve and mesenteric lymphadenopathy were observed. In three patients with Henoch-Schönlein purpura, initial abdominal ultrasonography showed intussusception. The patients with no sign of obstructive symptoms were managed conservatively with a diagnosis of intramural hemorrhage and on follow up the ultrasonographic findings of intussusception was resolved. One patient with the target sign on computed tomography and ultrasonography of the abdomen underwent ileocolic resection and end-to-end anastomosis due to a tumor in the cecum. There was no evidence of intussusception. One patient with a cyst in the right lower quadrant accompanying intussusception on ultrasonography of the abdomen underwent ultrasonography-guided reduction but the ultrasonographic findings persisted. On exploration, only cecal duplication cyst without intussusception was detected. Cecal resection including the cyst and end-to-end ileocolic anastomosis were performed.

CONCLUSIONS

Ultrasonography, color Doppler ultrasonography, barium or hydrostatic enema and computed tomography are helpful in diagnosing intussusception, but patients with radiologic findings of intussusception should be evaluated on symptoms and clinical findings before surgical intervention. Also, other diseases mimicking intussusception should be kept in mind in the differential diagnosis.

Duplication cysts: Diagnosis, management, and the role of endoscopic ultrasound

Gastrointestinal tract duplication cysts are rare congenital gastrointestinal malformation in young patients and adults. They consist of foregut duplication cysts, small bowel duplication cysts, and large bowel duplication cysts. Endoscopic ultrasound (EUS) has been widely used as a modality for the evaluation and diagnosis of duplication cysts. EUS is the diagnostic tool of choice to investigate duplication cysts since it can distinguish between solid and cystic lesions. The question of whether or not to perform EUS-fine needle aspiration (EUS-FNA) on a lesion suspected of being a duplication cyst is controversial as these lesions can become infected with significant consequences, although EUS-FNA is often required to obtain a definitive diagnosis and to rule out more ominous lesions. This manuscript will review the literature on duplication cysts throughout the body and will also focus on the role of EUS and FNA with regards to these lesions.

Prenatal sonographic findings of duodenal duplication: case report

We report a rare case of duodenal duplication cyst that was suspected prenatally. Routine prenatal sonography (US) at 19 weeks' gestation showed an abdominal cystic mass on the left side of the abdomen. Follow-up US examinations showed a partial "double-wall" sign, highly suggestive of enteric duplication, and changes in cyst size and wall thickness. Postnatal US examination suggested enteric duplication cyst. A laparotomy revealed a duodenal cyst that was completely resected. The antenatal US findings associated with this condition, the accuracy of its antenatal diagnosis, and its differential diagnosis are discussed.

Completely isolated enteric duplication cyst associated with a classic enterogenous duplication cyst

This report describes an 18-month-old boy with a completely isolated duplication cyst (CIDC) of the ileum associated with another classic enteric duplication cyst in the adjacent bowel and presenting as an acute abdomen due to torsion of the pedicle of the CIDC. Cysts excision was curative.

Foregut duplication cyst presenting as lingual swelling: Case report and review of literature

Congenital lingual cystic masses are challenging entities that can be detected prenatally or are discovered in various forms after birth. Foregut duplication cyst of tongue is an extremely rare condition. Here we present the eleventh case in literature on foregut duplication cyst in tongue lined with gastric mucosa. Complete excision was curative with no recurrence on followup.

Ileal atresia with duplication cyst of terminal ileum: a rare association

A case of ileal atresia in association with duplication of terminal ileum is being reported here.

Duodenal duplicated cyst manifested by acute pancreatitis and obstructive jaundice in an elderly man

A duodenal duplication cyst is an uncommon congenital anomaly that is usually encountered during infancy or in early childhood. Duodenal duplication cysts generally appear on the first or second portion of the duodenum and may cause duodenal obstruction, hemorrhage or pancreatitis. Here, we report a case of a duodenal duplication cyst on the second and third portion of the duodenum in an old aged man with obstructive jaundice and acute pancreatitis, which was treated successfully by a surgical excision.
