AbstractIntravascular papillary endothelial hyperplasia (IPEH) (Masson's tumor) is an unusual benign vascular lesion of the skin and subcutaneous tissue, consisting of papillary formations related to a thrombus and covered by a single layer of plump endothelial cells. The lesion is often mistaken with angiosarcoma and a group of other benign and malignant vascular lesions. The clinical and radiological findings are not specific, and the diagnosis is based on the histological examination. Intracranial lesions are extremely rare with only 32 cases been reported in the literature. Only two cases of IPEH presenting as scalp swelling have been reported in the literature. We report a case of a 3-month-old boy with IPEH of scalp in the left parietal region, which was involving the skull bone and extending intracranially.
