Adult primary retroperitoneal cavernous hemangioma: a case report

Abstract

Primary retroperitoneal cavernous hemangioma (PRCH) in an adult is extremely rare. We report on the diagnosis and treatment of a patient with PRCH with subtle clinical features and atypical findings on imaging scans. A 38-year-old man was admitted to hospital with a 5-day history of epigastralgia after alcohol drinking. Using various imaging methods, we found a giant cyst-like retroperitoneal mass compressing the surrounding organs. Surgical resection of the tumor was performed, and the mass was found to be a cavernous hemangioma measuring 90 × 80 × 60 mm, with a thick fibrotic wall and extensive intracystic hemorrhage. Physicians should be aware that PRCH may mimic a cystic neoplasm, and that a large tumor size probably indicates intracystic hemorrhage. Surgical resection is a curative approach for PRCH.

Retroperitoneal tumor: giant cavernous hemangioma – case presentation and literature review

“…The literature review shows that in differential diagnosis of giant abdominal tumors, rare benign neoplasms should be considered in every case. Radical surgical resection resulted in full recovery in our patient, which corresponds to commonly found conclusions despite the huge diameters and the origin of retroperitoneal tumors [20, 21]. …”

Mixed Capillary Venous Retroperitoneal Hemangioma

“…Benign retroperitoneal neoplasms are uncommon, and vascular tumor such as hemangioma is rather exceptional, with only a few cases being reported [1–5]. Among the reported cases of retroperitoneal hemangiomas, cavernous is the most common, whereas venous hemangioma is unusual [1–3].…”

Large retroperitoneal hemangioma encompassing the renal vein

“…No lab abnormalities are classically associated RH. There is no apparent gender predisposition, 5 and cases have been reported in both children 6 and adults. 3 Although classically a benign tumour, RH can be locally invasive of adjacent structures and lead to destruction of neighboring organs.…”
