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

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.

KTP laser alone or combined with bleomycin for pharyngolaryngeal hemangioma: a lesion grade-based determination of prognosis

BACKGROUND

No standard potassium titanyl phosphate (KTP) laser treatment strategy is available yet for pharyngolaryngeal hemangioma.

OBJECTIVES

To explore the therapeutic effect of KTP laser, alone or combined with bleomycin injection, for pharyngolaryngeal hemangioma.

MATERIAL AND METHODS

This observational study included patients with pharyngolaryngeal hemangioma treated between May 2016 and November 2021: KTP laser under local anesthesia, KTP laser under general anesthesia, or KTP laser combined with bleomycin injection under general anesthesia.

RESULTS

A total of 60 patients were recruited, including 17, 19, and 24 patients with grade 1, 2, and 3 hemangiomas, respectively. A total of 21 patients underwent KTP laser under local anesthesia, 31 underwent KTP laser under general anesthesia, and 8 underwent KTP laser under general anesthesia combined with bleomycin. The cure rates were 100%, 89.5%, and 20.8% for grade 1, 2, and 3 lesions, respectively. The prognosis was significantly different among the grades of hemangioma (p < .001).

CONCLUSION

KTP laser treatment might be an effective treatment for adult patients with pharyngolaryngeal hemangioma. The size of the hemangioma might be the major factor influencing the prognosis. The method of anesthesia and whether it was combined with bleomycin injection might not affect the prognosis.

Acquired laryngeal hemangioma: A rare presentation in an adult

Laryngeal hemangiomas are rare vascular tumors that mostly present in children. The objective of this publication is to shed the light over this rare diagnosis. We report a case of adult onset of laryngeal hemangioma arising from the junction of the vocal fold and vocal process. The patient presented with a history of hoarseness of voice. An in-office laryngoscopy was performed that revealed a pink lobulated mass arising from the left hemilarynx. Intraoperatively, suspension microlaryngoscopy was performed; the lesion was identified and successfully resected using cold dissection technique. Histopathological analysis was consistent with laryngeal hemangioma. The patient is now a year post resection and remains asymptomatic without signs of recurrence. To conclude, adult onset of laryngeal hemangioma is very rare. When present, resection with either or both cold steel (microscissors) and laser have shown good outcome. Patients should be monitored afterwards for possible recurrence.

[Diffuse Hemangiomatosis in the Intra-Abdominal Cavity Mimicking Peritoneal Metastasis: A Case Report]

We call hemangiomatosis if hemangioma arises multifocally from single or multiple organs. It develops predominantly on liver, and there are just few cases of hemangiomatosis from greater omentum and mesentery. Herein, we present the imaging and histopathological findings including CT and MRI images of a 62-year-old male patient with a hemangiomatosis on liver, greater omentum and mesentery.

Cavernous hemangioma of mesentery involving the jejunum causing intestinal obstruction in an adult male

We present a rare case of a 45-year-old man with abdominal pain and features suggestive of intestinal obstruction. The CT scan of the abdomen demonstrated a large mesenteric mass involving the distal segment of jejunum. Surgical excision of the lesion and histopathological examination revealed the diagnosis of cavernous hemangioma.

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.

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.

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.

A mesenteric solid tumor with unusual features in a young male: A case report

The current study presents a mesenteric mesenchymal tumor case, with unusual features in diagnostic imaging and histology. A 16-year-old male was admitted to the hospital with abdominal pain. Computed tomography (CT) revealed an abdominal mass, 2 cm in diameter. The results of contrast-enhanced CT, magnetic resonance imaging and ¹⁸F-fluorodeoxyglucose positron emission tomography indicated no specific features suggestive of its histology. Two arteries branching from the superior mesenteric artery were observed feeding the hypervascular tumor. After endoscopic and other laboratory findings revealed no additional lesions, the lesion was diagnosed as a primary mesenteric tumor. As the possibility of malignancy and future bleeding from this tumor could not be ruled out, a resection of the tumor was performed. During the surgery, the tumor, which was well circumscribed and hypervascular, was located in the mesentery of the jejunum. The resected tumor did not exhibit typical histological characteristics, and was labeled as 'myxoid smooth muscle neoplasm of uncertain biologic potential'. At 2 years after surgery, the patient remained well without evidence of recurrence. As primary mesenteric tumors are rare, particularly in young patients, it is considered important that this type of unusual tumor be included in the differential diagnosis for mesenteric tumors.

Intra-abdominal fat. Part III. Neoplasms lesions of the adipose tissue

This article focuses on various cancerous lesions that are found beyond organs in the intra-abdominal fat and can be visualized with ultrasonography. These lesions are divided into five groups. The first group includes primary benign tumors containing adipocytes, such as lipoma, lipoblastoma, hibernoma and other lesions with an adipose tissue component, such as myolipoma, angiomyolipoma, myelolipoma and teratoma. The second group comprises primary malignant adipocytecontaining tumors, including liposarcoma and immature teratoma. The third group contains primary benign tumors without an adipocyte component that are located in intra-abdominal fat. This is a numerous group of lesions represented by cystic and solid tumors. The fourth group encompasses primary malignant tumors without an adipocyte component that are located in intra-abdominal fat. These are rare lesions associated mainly with sarcomas: fibrosarcoma, malignant fibrous histiocytoma, hemangiopericytoma and leiomyosarcoma. An epithelioid tumor at this site is mesothelioma. The last but not least group includes secondary malignant tumors without an adipocyte component located in intra-abdominal fat. This is the most numerous group with prevailing carcinoma foci. For each of these groups, the authors present ultrasound features of individual lesions and discuss their differential diagnosis. In the vast majority of cases, the material for cytological and histological analysis can be obtained during ultrasound-guided procedures. This is the advantage of this imaging modality.

Giant Cystic Arteriovenous Malformation of the Mesentery and the Role of Cross-Sectional Imaging in Occult Gastrointestinal Bleeding

A 29-year-old woman presented with profound iron-deficiency anemia. Cross-sectional imaging identified a mass in the ileal mesentery. Surgical resection was curative and revealed a giant cystic arteriovenous malformation. Our report highlights the role of cross-sectional imaging in the evaluation and management of iron-deficiency anemia and obscure gastrointestinal hemorrhage.

Resection of a laryngeal hemangioma in an adult using an ultrasonic scalpel: A case report

Adult laryngeal hemangioma is an extremely rare and slowly progressing vascular tumor. The present study describes the first reported case of a male with a large laryngeal hemangioma that was treated by ultrasonic scalpel. A 61-year-old male presented to our hospital with a recurrent pharyngeal foreign body sensation, without hoarseness, hemoptysis, expectoration or dyspnea. A blue-black mass was detected in the right pyriform sinus, with a morular surface and a wide pedicle positioned lateral to the right arytenoid cartilage and aryepiglottic fold under electronic laryngoscopy. Following tracheotomy under local anesthesia, right superior laryngeal artery ligation and laryngeal hemangioma resection via a lateral neck hypopharyngeal approach were performed under general anesthesia using an ultrasonic scalpel. Pathological examination verified that the tumor was a cavernous hemangioma. On day 11, subsequent to post-operative anti-inflammatory and symptomatic treatment, electronic laryngoscopy showed that the arytenoid mucosal edema had decreased and that the movement of the arytenoid was good. There was no recurrence of hemangioma during a 2-year follow-up period. Therefore, it is recommended that complete surgical resection using an ultrasonic scalpel should be considered for similar cases involving large laryngeal hemangiomas.
