A rare cause of recurrent gastrointestinal bleeding: mesenteric hemangioma

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.

Cavernous hemangioma of the mesorectum involving the rectum: a rare case report

BACKGROUND

Gastrointestinal hemangiomas are very rare and are even rarer in the mesorectum. It is not clear whether mesorectal hemangiomas originate in the bowel wall or in the mesorectum. For clinicians, to correctly identify the imaging features of mesorectal hemangiomas is important.

CASE PRESENTATION

We herein describe a case of a 31-year-old male that presented with hematochezia and sensation of rectal tenesmus. Both the rectal MRI and contrast-enhanced CT scan of the whole abdomen indicated rectal wall thickening, marked dilatation, and tortuous vessels around the rectum. In addition, a contrast-enhanced portal venous phase CT scan showed the dilation of portal vein, splenic vein and inferior mesenteric vein. The dilated inferior mesenteric vein extending down to the mesorectum, and became marked dilatation and tortuous vessels around the rectum. The patient underwent laparoscopic surgical resection of the mesorectal lesion and the involved portions of the rectum. The surgical samples underwent pathological analysis, and a diagnosis of cavernous hemangioma was confirmed. Seven days after surgery, the patient was discharged without postoperative complications.

CONCLUSIONS

This case highlights the imaging features of mesorectal hemangiomas. In addition, in this current case, the mesorectal hemangioma more likely originated in the mesorectum.

Cavernous Hemangioma: A Rare Cause of Massive Lower Gastrointestinal Bleeding

Due to their rarity, intestinal hemangiomas are not commonly considered as a cause of gastrointestinal (GI) bleeding. This report describes a patient who presented with massive, recurrent lower GI bleeding secondary to a cavernous hemangioma of the small intestine. The source of GI bleeding could not initially be identified despite using numerous diagnostic modalities. The lesion was eventually revealed on diagnostic laparoscopy and small bowel resection was performed.

Giant Mesenteric Mixed Hemangioma Misdiagnosed as Ovarian Cyst: A Case Report and a Literature Review

Hemangiomas are congenital vascular disorders that occur primarily in the face and neck, extremely rare in the mesentery. Here, we report a rare small mesenteric mixed hemangioma. A 34-year-old woman was admitted to the gynecology department for an extended menstrual cycle. A cystic multi-atrial mass at the right anterior of uterus was observed by ultrasound examination, which was about 12.5 × 9.5 × 14.9 cm in size. The gynecologist mostly considered the possibility of the ovarian cyst. However, there was a huge multi-atrial cyst in the small intestine mesentery without the right ovarian cyst in the surgical exploration. The grape-like cystic mass about 15 cm in diameter adhered to the mesenteric root of the small intestine. The cyst was diagnosed as the mesenteric mixed hemangioma in the final histopathology.

Mesenteric infantile hemangioma: diagnostic work-up

A very rare localization of infantile hemangioma (IH) is mesentery. It may manifest with intra-luminal or intra-peritoneal bleeding. Here there is the case of a 45-day-old infant, presenting with anemia and poor growth, subsequently referred to an uncommon hemangioma of the mesentery. As well as for most of IH, conservative treatment with only propranolol resulted in the disappearance of the lesion. Here we analyze ultrasound and magnetic resonance (MR) features of this uncommon lesion, trying to underline main characteristics at imaging in order to monitor the response to therapy.

Beyond hepatic hemangiomas: the diverse appearances of gastrointestinal and genitourinary hemangiomas

Hemangiomas are common lesions, best known for their appearance in the liver. Their appearance in less common locations, such as the gastrointestinal and genitourinary tracts, is less well known. We will review the typical and atypical appearance of hemangiomas in these locations on sonography, CT, and MRI.

A hemangioma of the sigmoid colon mesentery presenting as a retroperitonealtumor: a case report and review

Hemangiomas of the gastrointestinal tract and mesentery are uncommon benign vascular lesions. While spontaneous bleeding is the hallmark of the gastrointestinal tumor variant, clinical signs of mesenteric hemangiomas are mostly unspecific. Despite the increasing imaging quality of computerized tomography (CT), in most cases the final diagnosis is established through surgery and histopathologic analysis of a macrobiopsy.

We present a case report of a 20-year-old female patient who was admitted with progressive abdominal distension and suffered from persistent abdominal pain for 3 months. A large retroperitoneal tumor mass was detected on the CT scan. Due to radiographic signs of an intraabdominal liposarcoma, an explorative laparotomy was performed revealing a large hemangioma originating from the mesosigmoid.

Although rare, gastrointestinal hemangiomas should be kept in mind by oncological visceral surgeons as one differential diagnosis of large intraabdominal tumorous masses, especially in young adults.

Giant mesenteric hemangioma of cavernous and venous mixed type: a rare case report

Background

Although vascular tumours are one of the most common soft tissue neoplasms, those occurring in the gastrointestinal system are rare and cases involving mesentery are even further rare. Herein, we reported a rare case of giant hemangioma in mesentery of the small bowel.

Case presentation

A 5-year-old girl was admitted to the emergency room with abdominal pain and vomit for two days. Ultrasonography and computed tomography showed a giant solid-cystic abdominal mass, preferring diagnosis of teratoma. A large neoplasm in the mesentery of the small bowel was found in the surgical exploration, which was then resected with the partial bowel. A brown honeycomb mass in size 16 cm×8 cm×5 cm was observed to adhere to the small bowel, and diagnosed as hemangioma of cavernous and venous mixed type in final pathology.

Conclusion

The mesenteric hemangioma is extremely rare and the variable imaging tests are non-specific, thus the diagnosis is rarely made before surgery and usually established by histopathological investigation after surgery. So the mesenteric hemangioma is supposed to be differentiated in abdominal mass, either in adults or children. Complete surgical resection is the optimal treatment.

Gastrointestinal bleeding caused by ileal metastasis of a tubal complete mole: a case report

BACKGROUND

Tubal hydatidiform mole is known to be an extremely rare disease, moreover, gastrointestinal metastasis from an ectopic complete mole has never been reported.

MATERIALS AND METHODS

A 33-year-old woman presented with gastrointestinal bleeding. She had undergone laparoscopic left salpingectomy for a tubal complete mole a month earlier. An ileal invasion of mole was identified. The patient received nine cycles of adjuvant methotrexate chemotherapy after small bowel resection and anastomosis. She was been without recurrence 20 months after therapy.

DISCUSSION

Gestational trophoblastic diseases in ectopic pregnancy are rare and gastrointestinal tract metastasis is very infrequent. There have been a few case reports of choriocarcinoma presenting gastrointestinal tract metastasis. To our knowledge, this is the first report of molar pregnancy in a Fallopian tube with ileal metastasis.

CONCLUSION

Ectopic molar pregnancy with gastrointestinal metastasis carries a high risk of intestinal perforation and uncontrollable gastrointestinal bleeding. Despite its rarity, gastrointestinal metastasis should nevertheless be considered a possible cause for gastrointestinal bleeding in ectopic molar pregnancy patients after elimination of the more common etiologies.
