An 8-year-old boy presented to our hospital complaining of a bilateral headache associated with episodes of anterograde amnesia. He had a road traffic accident 3 years ago when a computed tomography (CT) scan revealed traumatic brain injury. In addition, a small pineal cyst (PC) was noted with minor intramural calcifications. A follow-up CT a day later demonstrated increased density in the pineal gland of 60 Hounsfield Units, suggestive of apoplectic changes in the PC. However, the patient was lost to follow-up and presented with memory loss a year and a half later, upon which CT and magnetic resonance imaging revealed enlargement of the PC. PC apoplexy is a very rare occurrence usually affecting young adult women; cases in children are rarely reported. Furthermore, PC apoplexy secondary to severe craniofacial trauma manifesting as memory loss has not yet been reported in the literature to the best of our knowledge.
