This 3-month-old child presented with an enlarging head circumference arising from communicating hydrocephalus with large subarachnoid spaces in the posterior fossa. Neuroimaging performed to clarify the origin and pathogenesis of the hydrocephalus revealed a vascular lesion within the dorsal spinal cord. Insertion of a cerebrospinal fluid shunt and total removal of the spinal tumor were performed successfully. Histological examination of the medullar lesion demonstrated a capillary hemangioma. Proposed mechanisms for increased intracranial pressure and spinal cord lesions are presented. A spinal hemangioma in this age range associated with hydrocephalus has not been reported previously, but spinal lesions must be considered in the presence of hydrocephalus with no clear origin.
这名3个月大的儿童因交通性脑积水伴后颅窝大蛛网膜下腔导致头围增大。为明确脑积水的起源和发病机制而进行的神经影像学检查显示脊髓背侧有一个血管病变。成功进行了脑脊液分流管置入和脊髓肿瘤全切术。对延髓病变的组织学检查显示为毛细血管瘤。本文提出了颅内压升高和脊髓病变的可能机制。此前尚未报道过该年龄范围内的脊髓血管瘤伴脑积水，但在脑积水原因不明时必须考虑脊髓病变。
