Arachnoid Cyst with Intracystic Hemorrhage in a Child: Need For Vigilance and Prompt Treatment (P6.324)

We report a case of a 7 year old boy admitted with acute bilateral arm paresthesia, in the setting of possible prior head and neck trauma during trampoline play. He frequented the Emergency Department twice in the preceding month with new onset headaches, emesis and neck pain. Physical examination was pain limited, and non-focal. CT C spine did not show signs of trauma. The following day, the patient developed diplopia and was sent for MRI brain which showed large anterior and middle cranial fossa AC with bleed causing significant mass effect and herniation. He was taken for urgent SDH evacuation with drain placement. Post-operatively he rapidly improved back to full baseline functionality. This case highlights the diagnostic difficulties of AC with intracystic hemorrhage, particularly in children with unusual and delayed presentation. It also indicates need for close follow up among patients with AC and minor head trauma. Disclosure: Dr. Naqvi has nothing to disclose. Dr. Katramados has nothing to disclose.
