Renal hemangioma is an uncommon benign tumor which usually causes painless or painful gross hematuria. Its preoperative diagnosis is extremely difficult or even impossible. We experienced three cases of renal hemangioma, located mainly at the pelvocalyceal junction or in the inner medulla. US demonstrated variable echogenecity, and CT revealed a lack of significant enhancement. Where there is g...

A case of intramuscular hemangioma of the right forearm and hand muscle is presented in this study. This tumor may infiltrate the muscle and be misdiagnosed as a malignant neoplasm. The patient, a 14-year-old girl, presented to the clinic with right forearm and hand pain and swelling which began when she was 2 years old and had been gradually increasing in size. Because the mass might have been...

We describe the case of an 18-year-old female with Cowden syndrome in whom a simple x-ray detected a solitary pulmonary nodule that was identified as a sclerosing hemangioma. Pulmonary sclerosing hemangioma is an unusual lung neoplasm which typically presents as a solitary peripheral nodule in asymptomatic women. Although the histology of this entity is well defined, its origin and treatment is...

Hepatic hemangiomas are the most frequently seen benign liver mass. However, exophytic hepatic hemangiomas, particularly pedunculated ones are very rare. They have various appearances that make the diagnosis difficult. We report a pedunculated hemangioma case which was misdiagnosed as gastrointestinal stromal tumor on computerized tomography scan. Magnetic resonance imaging revealed that the tu...

Hemangioma of the urinary bladder is a rare and benign tumor which may be present at any age. Among all kinds of bladder tumors, hemangioma of the bladder constitutes just 0.6 % of them. It consists of numerous proliferative capillaries united with thin-walled, expanded blood-filled vessels that are covered by flat endothelial cells. Here, we present a case of a 60 years old man referred to our...

Surface-based bone hemangiomas are uncommon, mostly occurring in long bones of the lower extremities. Radiographic surface-based bone hemangioma images may present various features that provide a diagnostic challenge. We report a case of surface-based hemangioma of the radius that posed radiological diagnostic difficulties. The tumor size was small and the cortical reaction was subtle. MRI find...
