Capillary hemangiomas are the most common tumor of the neck and head in children. Intracranial capillary hemangioma without generalized neuro-cutaneous hemangiomatosis is extremely rare, with only one report in the literature. We report a case of intracranial capillary hemangioma originating from the temporal base. An 8-year-old boy presented with a severe headache and nausea. A CT scan showed a low-density area in the left temporal lobe and an iso-density mass at the temporal base. This mass was enhanced by contrast medium. The mass lesion appeared as an iso-intensity area on T1-weighted MR images and as a high-intensity area on T2-weighted MR images, and the mass was enhanced almost uniformly by gadoliniumdiethylene triaminepenta-acetic acid. Cerebral angiography showed abnormal staining fed by the anterior temporal artery. An operation was performed, and all of the tumor with the dura attached was removed. The histological diagnosis was capillary hemangioma. The tumor consisted of a proliferation of capillary vessels lined by a single layer of endothelial cells. In this paper, we review the clinical features, neuro-imaging findings and proposed etiology of capillary hemangioma.

Introduction: Retinal capillary hemangioma (RCH) is a benign vascular hamartoma that can occur sporadically or as a manifestation of Von Hippel-Lindau (VHL) disease. If left untreated, it results in adverse ocular complications depending on its location and eventual visual loss.
Case Presentation: We present a 50-year-old man who was a known case of VHL with history of left eye vision loss in the left eye at the age of 30 years.

Intrarenal hemangiomas lack concise clinicopathologic information, due to the predominance of single case reports and inclusion of other vascular neoplasms and hemangiomas of perirenal, hilar, and renal vein origin. Herein, in this multi-institutional study we evaluate clinicopathologic features of 39 intrarenal hemangiomas. The median age was 62 years (range = 27-94 years; 2:1 male to female ratio), with left-sided predominance (left = 21, right = 13; one case was bilateral).

Vascular anomalies are broadly classified into 2 categories: vascular tumors and vascular malformations. Vascular anomalies frequently present as cutaneous lesions in infants. This review summarizes vascular anomalies that most commonly present as dermatologic lesions in the neonatal period, with a focus on the clinical findings, pathophysiology and histology, relevant radiographic findings, and management of common vascular anomalies such as infantile hemangiomas, congenital hemangiomas, and Kaposiform hemangioendothelioma, along with vascular malformations, including capillary, lymphatic, venous, and arteriovenous malformations.
