Ultrasonographic features of an intravascular lobular capillary hemangioma originating in the basilic vein: Case report and literature review.

Intravascular lobular capillary hemangioma (ILCH) is a rare variant of pyogenic granuloma, which develops within the lumen of a blood vessel. Here, we report the case of a 38-year-old male presenting with a mobile, incompressible, nonpulsatile nodule in the superficial fascia of the forearm. A first ultrasonographic examination diagnosed the mass as intravascular thrombosis with partial recanalization. Three months later, a second ultrasonographic examination concluded to the existence of an intravascular tumor, which finally turned out at pathological examination to be ILCH. Here, we report the ultrasonographic features of ILCH and the differential diagnosis between ILCH and other intravascular masses like thrombus.
