Pineal Cyst Apoplexy: A Rare Complication of Common Entity

ABSTRACT

Pineal cysts (PCs) are often encountered as incidental findings in intracranial images. The vast majorityof cysts are normally asymptomatic and clinically benign. Bleeding into the cysts, which leads to neurologicalsymptoms and signs, is considered to be quite rare. The authors illustrate a newly identifiedcomplication of PC in a 56-year-old woman who characterized by headache of sudden onset and vomiting.MRI disclosed a small hemorrhagic PC without narrowing of the cerebral aqueduct. The patientwas managed conservatively without any surgical interventions, and she remained symptom-free overa period of 15-year follow-up. The description of this case adds to the limited literature on the series inwhich nonsurgical treatments had a role in the care for patients with PC complicated by intracystichemorrhage.
