Cystic choroid plexus tumor is a rare variant of choroid plexus papilloma (CPP), reported mostly in infants. It is associated with the development of acute hydrocephalus in many cases. The presence of atypical CPP has recently been recognized by the WHO as a grade II tumor with increased mitotic activity. We are reporting a case of a 3.5 month infant who presented with seizures and features of increased intracranial pressure. He was found to have cystic atypical choroid plexus papilloma.
脉络丛囊性腺瘤是脉络丛乳头瘤（CPP）的一种罕见变异型，多发生于婴儿。在许多情况下，它与急性脑积水的发展有关。最近，世界卫生组织（WHO）将非典型 CPP 确认为一种具有较高有丝分裂活性的二级肿瘤。我们报告了一例 3.5 个月大的婴儿，该婴儿出现癫痫发作和颅内压增高的表现。他被诊断为囊性非典型脉络丛乳头瘤。
