“…5,20,31,33) Unlike other angiomatous tumors, the proliferation of endothelial cells in IPEH is confined to the vascular lumen. The paucity of mitosis, foci of necrosis, and solid cellular areas without vessel formation may also help to distinguish this entity from neoplasms.…”

Four rare cases of intracranial intravascular papillary endothelial hyperplasia (IPEH) manifesting as cranial nerve disturbances occurred in 16-, 18-, 24-, and 28-year-old females. Magnetic resonance imaging showed all lesions as isointense with strong enhancement on T 1 -weighted images, and as hyperintense on T 2 -weighted images. All lesions were removed via craniotomies. Histological examination found vascular structures and papillary spaces lined with endothelial cells showing immunoreactivity for CD31. Complete removal was curative in two cases, whereas incomplete removal resulted in cure in one case and residual deficits in one case. Iatrogenic deficits should be avoided in IPEH treatment by surgery. Differentiation from neoplasm such as angiosarcoma depends on histological characteristics.

“…Intravenous atypical vascular proliferation is the intravascular form of epithelioid hemangioma. 13 Although it also develops within the lumen of a vessel, it shows solid rather than papillary endothelial proliferation, contains epithelioid endothelial cells and may extend into the vascular wall and beyond. 10 Although spindle cell hemangioendothelioma is usually associated with organizing thrombi, it is considered a neoplasm of intermediate malignancy, 4 though a reactive process was suggested recently.…”

“…In support of the distinct entity hypothesis, several cases of JTA without endothelial proliferation have been reported. 4,10,11,32,33 To support the alternative hypothesis, involvement of the other medium muscular arteries (eg, facial and radial) by a process with histopathologic findings of ALHE has been reported, [34][35][36][37][38][39] although frequently with no evidence of arteritis. 39 Several cases with histopathology of JTA have been reported in conjunction with systemic abnormalities, such as nephrotic syndrome, eosinophilia of 31% with multiarterial involvement (including bilateral temporal artery involvement), and history of lymphoma.…”
