Ultrasonographic Evaluation of Intravenous Lobular Capillary Hemangioma in the Cephalic Vein

摘要

A 60-year-old man presented with focal swelling on the dorsal surface of the left wrist. The sonographic exam revealed the presence of a smoothly rounded hypoechoic mass, with internal blood flow in the lumen of the vein. The histopathological findings led to the diagnosis of intravenous lobular capillary hemangioma (LCH). Here, we reported an intravenous LCH arising from the cephalic vein on the dorsal surface of the left wrist hand and discussed the related ultrasonographic findings. Lobular capillary hemangioma (LCH), also known as pyogenic granuloma, is a relatively common benign vascular tumor that develops spontaneously on the skin and mucous membranes or as a result of trauma or minor surgery. Intravenous LCH is a rare solitary form of LCH and usually occurs in the neck and veins of the upper extremities. It has been documented as affecting individuals aged 15-66 years, with an average age of manifestation of 38 years and a slight predominance in females.[1] Intravenous LCH was previously thought to be a lesion that developed secondary to trauma and pyogenic infection, based on its lobular vascular proliferation that appears to be neoplastic. The presence of locules under ultrasonography (US) was a hallmark presentation of intravenous LCH.
