Intracranial infantile hemangiopericytomas (HPCs) are exceedingly rare lesions. Only 11 cases have been previously reported in the literature. As such, little is known about the etiology, long-term prognosis, and optimal treatment paradigm. Clinically, they are consistently less aggressive than those in adults.

McHugh et al., present the case of a 2-month-old boy with an intracranial HPC, review the available literature, discuss the evolving concepts of what defines an HPC, and offer a potential explanation to how HPC histology might relate to the clinical behavior of these lesions (McHugh BJ, Baranoski JF, Malhotra A, Vortmeyer AO, Sze G, Duncan CC. Intracranial infantile hemangiopericytoma. J Neurosurg Pediatr. 2014 Jun 6:1-6. [Epub ahead of print] PubMed PMID: 24905842.)).
