Small bowel racemose hemangioma complicated with obstruction and chronic anemia: A case report and review of literature

Multiple Small Bowel Cavernous Hemangiomatosis: Case Report and Literature Review

A 79 year old female individual presented to the hospital and complained of 1 month melena and anemia due to chronic gastrointestinal bleeding because of cavernous hemangiomatosis of the small bowel. After undergoing an initial video laparoscopic jejunal-ileal resection surgery 7 days after first hospitalization, given the persistence of anemia, she underwent laparotomic duodenojejunal resection surgery again 2 months later. Multiple cavernous hemangiomatosis is a rare vascular disease (7-10% of all benign small bowel tumors), and it often manifests with bleeding, which may be occult or massive; more rarely, it manifests with intestinal occlusion or perforation. Diagnoses often require the use of multiple radiological and endoscopic methods; video capsule endoscopy has significantly increased the diagnostic rate. The gold standard of treatment is surgical resection, whenever possible, balancing the need for radicality with the possible metabolic consequences of massive small intestine resections.

Management of a small bowel hemangioma causing intussusception in an infant: A rare case report and literature review

INTRODUCTION

Hemangiomas of the small intestine are rare and usually present in young people. They are very difficult to diagnose preoperatively. We report a rare case of mixed intestinal hemangioma (IH) causing intussusception in a pediatric patient.

CASE PRESENTATION

A 3-month-old girl, with no prior medical or surgical history, was admitted with rectal bleeding and paroxysmal crying due to intermittent abdominal pain. An urgent abdominal ultrasound revealed ileo-ileal intussusception. Operative findings confirmed the intussusception, and a segmental resection of the intussuscepted jejunum was performed. Histopathological examination found a mixed hemangioma. The postoperative course was uneventful.

DISCUSSION

Clinical presentation may include intestinal bleeding leading to anemia, obstruction, intussusception and perforation. Intussusception caused by small bowel hemangioma is extremely rare. Notably, we didn't find any cases of small bowel hemangioma revealed by intussusception in children. The main treatment for hemangiomas is surgical resection of the affected segment. No evidence in the literature on postoperative recurrence of hemangiomas.

CONCLUSION

Intussusception secondary to intestinal hemangiomas is extremely rare. Preoperative diagnosis is challenging as they are often undetectable with traditional techniques. Enhanced awareness and understanding of this condition can facilitate earlier diagnosis and improve management outcomes.

Endoscopic injection of lauromacrogol foam sclerotherapy for rectal cavernous hemangioma: A case report

RATIONALE

Rectal cavernous hemangioma is a rare, benign vascular disease that seldom causes lower gastrointestinal bleeding, characterized by a high rate of misdiagnosis and missed diagnoses. Surgical treatment is considered to be relatively effective; however, it is accompanied by certain employed in the treatment of superficial hemangioma, boasting the advantages of minimally invasive surgery, including safety, effectiveness, reduced trauma, and rapid recovery. However, there is a lack of literature regarding the application of foam sclerosing agents for gastrointestinal hemangiomas.

CASE CONCERNS

We present a case of a 60-year-old male who was admitted to our hospital with a history of recurrent hematochezia for >1 year and worsening symptoms for 1 week. The patient's medical history was unremarkable.

DIAGNOSES

Following colonoscopy, nuclear magnetic resonance imaging, computed tomography, and other examinations, the final diagnosis was rectal cavernous hemangioma.

INTERVENTIONS

Due to the patient's refusal of surgery, endoscopic foam sclerotherapy using a lauromacrogol injection was performed after obtaining informed consent from the patient and their relatives.

OUTCOMES

Post-sclerotherapy, hematochezia symptoms ceased, and no adverse reactions were observed. Two months later, colonoscopy and nuclear magnetic resonance imaging showed that the hemangioma had almost completely disappeared, with only a small amount of tumor remnants, yielding a satisfactory curative effect.

CONCLUSION

Our findings indicate that endoscopic injection of a lauromacrogol foam sclerosing agent is a safe, effective, and minimally invasive treatment option for gastrointestinal cavernous hemangiomas.

Transumbilical single-site laparoscopic treatment of small intestinal cavernous hemangioma in child: a case report

Background

While hemangiomas are the most commonly occurring benign vascular tumors, their occurrence in the gastrointestinal system is rare. This case report presents a unique instance of small intestinal hemangioma in a pediatric patient.

Case description

A 21-month-old girl was admitted to the hospital with a history of "recurrent blood in the stool for one year and anemia for five months." Upon evaluation at our facility, abdominal color ultrasound and enhanced CT scans revealed a protruding mass in the wall of the small intestine, leading to a preliminary diagnosis of small intestinal hemangioma. Subsequent single-site umbilical laparoscopic exploration identified a tumor measuring approximately 6cm×2.5cm×1.2cm on the jejunum wall. Consequently, segmental resection of the intestine was performed, and the postoperative pathological diagnosis confirmed cavernous hemangioma.

Conclusion

Small intestinal hemangiomas, particularly in pediatric patients, are exceptionally rare and challenging to diagnose as the cause of gastrointestinal bleeding prior to surgery. Hence, small intestinal hemangiomas should be considered in such cases. Laparoscopic surgical resection emerges as the optimal approach for addressing small intestinal hemangiomas.

Solitary Ileal Hemangioma in a 3-year-old Male

Hemangiomas are rare small bowel tumors requiring a high index of suspicion for diagnosis. We present a case of ileal hemangioma in a 3-year-old male presenting with recurrent anemia. The patient was diagnosed with a contrast-enhanced computed tomography abdomen and managed surgically by resection and anastomosis. Histopathologically, it was a solitary ileal cavernous hemangioma with a submucosal infiltrative pattern with serosa involvement and a normal mucosa.

An Endoscopic View of Multiple Hemangiomas of the Small Intestine

Small intestinal hemangiomas may present as a severe gastrointestinal hemorrhage associated with a hematologic emergency. In the emergent setting, this may result in more extensive intestinal resection than would otherwise be necessary with elective intervention. The widespread application of capsule endoscopy and double-balloon enteroscopy presents an opportunity to diagnose small bowel hemangiomas prior to symptomatic onset. In one of the first published cases of multiple small intestinal hemangiomas, we highlight the importance of maintaining a broad differential and pursuing a thorough workup, including small bowel imaging, in patients with complaints of chronic abdominal pain and anemia.

Jejunal Cavernous Hemangioma Mimicking Malignancy With Increased Activity on 18 F-FDG PET/CT

ABSTRACT

A 50-year-old woman underwent 18 F-FDG PET/CT to evaluate possible abdominal malignancy, which was revealed by CT. The images showed a large cystic-solid lesion with peripherally increased FDG activity in the left mid-abdomen. Histopathology of the excised lesion confirmed a jejunal cavernous hemangioma. We reported a rare case of jejunal cavernous hemangioma with FDG accumulation on PET/CT, mimicking malignancy.

Cavernous hemangioma of the ileum in a young man: A case report and review of literature

BACKGROUND

Small intestinal cavernous hemangioma is a rare disease, especially in the ileum. It is difficult to accurately diagnose due to its hidden location and nonspecific clinical symptoms. Here, we reported a case of ileal cavernous hemangioma with chronic hemorrhage in a 20-year-old man and review the literature to gain a better understanding of this disease.

CASE SUMMARY

The patient complained of intermittent melena and hematochezia for > 3 mo. The lowest hemoglobin level revealed by laboratory testing was 3.4 g/dL (normal range: 12-16 g/dL). However, the gastroscopy, colonoscopy and peroral double-balloon enteroscopy (DBE) showed no signs of bleeding. The transanal DBE detected a lesion at about 340 cm proximal to the ileocecal valve. Thus, we performed an exploratory laparoscopy and the lesion was resected. After the operation, the patient had no melena. Finally, the pathological examination identified the neoplasm as an ileal cavernous hemangioma, thereby resulting in gastrointestinal hemorrhage.

CONCLUSION

This report might improve the diagnosis and treatment of ileal cavernous hemangioma.

Anemia induced by hemangioma at the duodenal papilla, resected by endoscopic mucosal resection

A 7-year-old ever healthy girl presented to our hospital with anemia for half-a-year, and her lowest hemoglobin level was 75g/L. She denied any hematemesis or melena, however her fecal occult blood test was positive. Computed tomography revealed an oval lesion in the descending duodenum.

Sirolimus for diffuse intestinal infantile hemangioma with PHACE features: systematic review

BACKGROUND

We report a 3-month-old female with cardiovascular anomalies and diffuse intestinal infantile hemangioma (IIH) of the small bowel suggesting possible diagnosis of PHACE syndrome (posterior fossa anomalies, hemangioma, arterial lesions, cardiac abnormalities/coarctation of the aorta, eye anomalies). The GI symptoms persisted under treatment with propranolol, whereas the addition of sirolimus led to regression of the IIH.

METHODS

A systematic review was conducted using PubMed, EMBASE, and Ovid MEDLINE databases between 1982 and 2021.

RESULTS

A total of 4933 articles were identified; 24 articles met inclusion criteria with 46 IIH cases. The most common GI presentations were unspecified GI bleed (40%) and anemia (38%). The most common treatments were corticosteroids (63%), surgical resection (32.6%), and propranolol (28%). Available outcomes were primarily bleeding arrest (84%). Nine cases (19.5%) were diagnosed with definite PHACE, 5 (11%) with possible PHACE, and 32 (69.5%) no PHACE. Our case presented with symptoms most consistent with those of possible PHACE and definite PHACE. No cases in this review underwent treatment with sirolimus.

CONCLUSIONS

This is the first reported case of successful treatment of IIH with sirolimus. Our case, along with other patients who present with IIH and PHACE features, suggests consideration of IIH as a diagnostic criterion for PHACE syndrome.

IMPACT

This is the first reported case in which sirolimus showed regression of an intestinal infantile hemangioma. This study serves to demonstrate the presentation, treatment, outcomes of intestinal infantile hemangioma, and correlation with PHACE. The potential correlation between intestinal infantile hemangioma and PHACE deserves more study in consideration of intestinal infantile hemangioma as a diagnostic criterion of PHACE.

Single-Cell Transcriptome Analysis Reveals Mesenchymal Stem Cells in Cavernous Hemangioma

A cavernous hemangioma, well-known as vascular malformation, is present at birth, grows proportionately with the child, and does not undergo regression. Although a cavernous hemangioma has well-defined histopathological characteristics, its origin remains controversial. In the present study, we characterized the cellular heterogeneity of a cavernous hemangioma using single-cell RNA sequencing (scRNA-seq). The main contribution of the present study is that we discovered a large number of embryonic mesenchymal stem cells (MSCs) in a cavernous hemangioma and proposed that cavernous hemangiomas may originate from embryonic MSCs. Further analysis of the embryonic MSCs revealed that: 1) proinflammatory cytokines and related genes TNF, TNFSF13B, TNFRSF12A, TNFAIP6, and C1QTNF6 are significantly involved in the MSC-induced immune responses in cavernous hemangiomas; 2) UCHL1 is up-regulated in the embryonic MSC apoptosis induced by proinflammatory cytokines; 3) the UCHL1-induced apoptosis of MSCs may play an important role in the MSC-induced immune responses in cavernous hemangiomas; and 4) UCHL1 can be used as a marker gene to detect embryonic MSCs at different apoptosis stages. In addition to MSCs, ECs, macrophages, T lymphocytes and NKCs were intensively investigated, revealing the genes and pathways featured in cavernous hemangiomas. The present study revealed the origin of cavernous hemangiomas and reported the marker genes, cell types and molecular mechanisms, which are associated with the origin, formation, progression, diagnosis and therapy of cavernous hemangiomas. The better understanding of the MSC-induced immune responses in benign tumours helps to guide future investigation and treatment of embryonic MSC-caused tumours. Our findings initiated future research for the rediscovery of MSCs, cancers/tumours and the UCHL1-induced apoptosis.

Multiple intestinal hemangioma concurrent with low-grade appendiceal mucinous neoplasm presenting as intussusception-a case report and literature review

BACKGROUND

Cases with intussusception caused by either intestinal hemangiomas or appendiceal mucinous neoplasms are extremely rare.

CASE PRESENTATION

In this study, we reported a 47-year-old male presented with paroxysmal abdominal pain and postprandial bloating for 3 days. CT results indicated a high possibility of secondary intussusception in ascending colon. Histopathology indicated a mixed type of cavernous and capillary hemangioma, combined with low-grade appendiceal mucinous neoplasms (LAMNs) and intestinal obstruction. The patient underwent laparotomy and right hemicolectomy. Finally, the patient was followed up for 4 months with no disease progression.

CONCLUSIONS

Rare studies reported the intestine hemangiomas coincided with appendix low-grade mucinous tumor. Its manifestations are not specific, which is a challenge in the preoperative diagnosis. For cases with intussusception that was not observed in time, it may lead to intestinal necrosis and diffuse peritonitis. Additionally, the ruptured mucinous tumor in the appendix may lead to pathogenesis of pseudomyxoma peritonei. Therefore, accurate diagnosis and appropriate surgery-based treatment contribute to the improvement of prognosis and severe outcomes among these patients.

An incidentally identified 15 cm cavernous hemangioma of the small intestine: Case report and literature review

Introduction

Hemangiomas of the small intestine are rare, usually present with symptoms such as anemia, gastrointestinal bleeding or abdominal pain and are resected. We report resection of an incidentally identified cavernous hemangioma of the small intestine that did not present symptoms referable to the hemangioma. Although it was a large lesion, it was resected using laparoscopy and a mini-laparotomy.

Presentation of case

A 29-year-old otherwise healthy man was referred for evaluation of ileal wall thickening found on a contrast-enhanced computed tomography scan obtained for the workup of chronic diarrhea. Double balloon enteroscopy (DBE) showed a cavernous hemangioma of the small intestine. The lesion was 15 cm and resected using laparoscopy and a mini-laparotomy to prevent future bleeding. The histopathological diagnosis was a cavernous hemangioma of the ileum.

Discussion

Though there have been no reports of the asymptomatic patients of the disease, the recent spread of double balloon enteroscopy and capsule endoscopy will allow us to diagnose more asymptomatic hemangiomas like this patient. Also, this large lesion was able to be resected through a small incision due to its compressible nature.

Conclusion

Future studies in asymptomatic patients of the disease may help to determine the optimal management for these patients. Even large hemangiomas are compressible, facilitating minimally invasive resection.

•

Hemangiomas of the small intestine are rare disease.

•

They have always been diagnosed with symptoms such as anemia and bleeding so far.

•

An asymptomatic hemangioma of the small intestine was incidentally identified.

•

It was big, but laparoscopic resection was possible due to its compressible nature.

•

To determine the optimal treatment for asymptomatic lesions is a task in the future.

Ileal cavernous haemangioma in an adult presenting as a rare cause of small bowel obstruction

Haemangiomas of the small bowel are a very rare entity and rarely considered as an aetiology for an intestinal obstruction. Contrast-enhanced CT is the investigation of choice but the lesion can be confused with malignancy or rarely a neuroendocrine tumour. Commonly it presents as abdominal pain with anaemia and/or melaena. With patients presenting without obstruction or acute gastrointestinal bleed, capsule endoscopy has shown to be a useful diagnostic tool.We present here our experience of managing a case of a patient with ileal haemangioma who presented with a subacute small bowel obstruction and underwent a laparoscopic-assisted ileal segmental resection with side-to-side anastomosis. The lesion was a cavernous haemangioma on histopathological analysis.
