A Rare Case of Intracranial Hemorrhage Mimicking a Neoplasm in a Child With Hereditary Hemorrhagic Telangiectasia.

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder characterized by abnormal blood vessel formation, resulting in the development of arteriovenous malformations and telangiectasias throughout the body. We present a rare case of an intracranial hemorrhage mimicking a neoplasm in a medically complex pediatric patient with HHT, a diagnosis that was unbeknownst to both the clinical team and the interpreting radiologist early in the patient's clinical course. This case not only demonstrates the importance of obtaining a thorough medical history but having a clear understanding of the numerous manifestations of HHT, especially as it pertains to the pediatric population. We implore strictly adhere to the guidelines of brain imaging at the time of diagnosis, as well as a multidisciplinary approach to the surveillance and management of these patients in hopes of preventing serious and potentially fatal complications.
