RT Journal Article SR Electronic T1 Langerhans Cell Histiocytosis of the Skull Complicated with an Epidural Hematoma JF American Journal of Neuroradiology JO Am. J. Neuroradiol.

LCH complicated with a neurologic deficit due to the presence of epidural involvement is a rare condition. We describe the CT imaging features in a 2-year-old boy who presented with drowsy consciousness resulting from an epidural hematoma caused by spontaneous bleeding in an LCH of the skull. CT is an excellent means of depicting the full extent of bony destruction and the nature of the process.
