Diffuse cavernous hemangioma of the rectum: magnetic resonance imaging features: a case report

Diffuse cavernous hemangioma of the rectum (DCHR) is a rare benign vascular lesion usually seen in young adults. The presenting symptom is painless recurrent rectal bleeding. Herein, we report a 5 yearold male patient with a history of DCHR. He had been diagnosed with DCHR at his birth. The definite diagnosis was made on the basis of biopsy wich was performed during colonoscopic examination. The patient underwent magnetic resonance imaging (MRI) examination which revealed characteristic signal intensity features of the tumor and also determined the exact location and extent of the lesion. The tumor had only minimally progressed in size compared to the last MRI examination. Currently, the patient is on medical treatment and being followed up by MRI. DCHRs are rarely encountered and often misdiagnosed because they can mimic internal hemorrhoids, inflammatory bowel disease, carcinoma and various other pathological conditions. In conclusion, we can emphasize that despite its rarity, DCHR should be considered in the differential diagnosis of young patients presenting with painless recurrent rectal bleeding.

Rektumun diffüz kavernöz hemanjiomunda manyetik rezonans görüntüleme özellikleri: Olgu sunumu

Rektumun diffüz kavernöz hemanjiomu (RDKH) nadir rastlanan benign vasküler bir lezyon olup, genellikle genç yetiþkinlerde görülür. Aðrýsýz, tekrarlayan rektal kanama ile ortaya çýkar. Olgu bildirimizde RDKH hikayesi olan 5 yaþýnda bir erkek çocuk hastayý tanýmladýk. Hastanýn tanýsý doðum esnasýnda konulmuþtu. Kesin taný kolonoskopik inceleme sýrasýnda gerçekleþtirilen biyopsi ile yapýlmýþtý. Hastaya yapýlan manyetik rezonans görüntüleme (MRG) ile hem tümöre ait karakteristik sinyal intensite özellikleri ortaya kondu, hem de lezyonun kesin yeri ve uzanýmý saptandý. Tümör son MRG tetkiki ile kýyaslama yapýldýðýnda minimal boyut artýþý göstermekteydi. Hasta þu anda medikal tedavi görmekte ve MRG ile takip edilmektedir. RDKH ile nadiren karþýlaþýlýr ve internal hemoroidler, inflamatuar barsak hastalýklarý, karsinoma ve çeþitli diðer patolojik durumlarý taklit edebildiðinden sýklýkla yanlýþ taný konulur. Sonuç olarak nadir görülmesine karþýn, özellikle genç hastalarda aðrýsýz, tekrarlayan rektal kanamalarýn ayýrýcý tanýsýnda RDKH’nin göz önünde bulundurulmasý gerektiðini vurgulayabiliriz.
