Hepatic hemangiomas can be characterized, and diagnosis can be made by computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound (US). Stanford CA 94305-5342, , Benign vascular lesion of the breast large enough to be detected clinically, By definition, detectable by palpation or mammography, Large feeder vessels may be seen at periphery, Complete excision and examination is required for the diagnosis of any benign vascular lesion in the breast, Other benign vascular lesions of the breast, Intermediate and high grade tumors are cytologically atypical, Venous hemangioma may have muscular walls. There is similar sensitivity to MRI for lesions greater than 1 cm but has not been proven to have the same diagnostic value. Cavernous Hemangioma. Schwartz, S. et al. It is important to note, though, that multiple modalities are required for definitive diagnosis. Pyogenic granuloma is an acquired benign proliferation of capillary blood vessels of the skin and oral cavity. Topical administration may be indicated in small superficial lesions or in PHACES syndrome due to high risk of cerebral ischemia with systemic administration [8].
