Intramuscular cavernous hemangioma of brachioradialis muscle

Soft-tissue hemangiomas are a common neoplasm of the angiomatous lesion origin that appear chiefly during childhood and is responsible for approximately 7% of the benign tumors. They are the most common angiomatous lesions that primarily affect women more than men. Intramuscular cavernous hemangiomas are rare in the limbs (0.8% of all hemangiomas), and <20% are mainly found in the head-and-neck region. In general, it is more common in young adults who have suffered from any kind of trauma. The frequency of hemangiomas is higher in the masseter muscle, whereas in very few cases, it is also observed in the buccinator muscle. An 18-year-old male presented at the tertiary care hospital with swelling in the right elbow measuring 1 cm × 1 cm. The swelling seemed to be arising from the right brachioradialis muscle. A benign cyst above the muscle plane was determined on the ultrasound examination. Furthermore, the excision biopsy sample collected for the histopathological examination showed irregularly dilated blood vessels lined with walls of varying thickness within the muscular plane. Based on the microscopic findings, the diagnosis of intramuscular cavernous hemangioma was made. The intramuscular cavernous hemangioma is a rare entity that makes it difficult to diagnose even with radiological investigations.
