BACKGROUND: The radiographic identification of @entity979 has increased dramatically within the last two decades due to the advent of magnetic resonance imaging. Pineal cysts are often found incidentally with only a minority of these lesions ever becoming symptomatic and requiring treatment. Many theories attempting to explain the pathogenesis of these cysts exist. METHODS: We describe a case of a 12-year-old @entity1 who presents with a @entity548 of unknown etiology with associated @entity1276 . RESULTS: Her @entity1276 was initially treated with an external ventricular drain followed by a third ventriculostomy. She had no evidence of elevated beta @entity1 chorionic gonadotropin or @entity160 within the serum or cerebrospinal fluid. Follow-up imaging at seven weeks revealed resolution of her @entity548 , however, there was development of a progressive @entity5409 within the pineal region. In order to make a definitive tissue diagnosis, a supracerebellar infratentorial surgical approach with complete resection was performed. During the resection, brownish fluid was aspirated from the cyst and the cyst wall was removed. The pathological diagnosis was a pineal cyst. CONCLUSIONS: Although cases have been described of pineal apoplexy with an underlying cyst, this case describes the development of a progressive pineal cyst secondary to a @entity548 . This case demonstrates that @entity548 may be a promotor for the development or progression of @entity979 .
