Abstract
|
|
|
|
A 42-year-old man presented with a headache and right hemiparesis and was found to have a cystic mass with a calcified mural nodule in the left thalamus. Because the thalamus is surrounded by vital neurovascular structures, the surgical approach to thalamic lesions can be challenging. We decided to remove the mass for decompression and pathological diagnosis. The mass was removed through a contralateral interhemispheric transcallosal transchoroidal approach with less retraction and parenchymal injury than other approaches to avoid brain retraction and cortical injury. The pathological diagnosis was cavernous malformation. Temporary worsening of the preoperative hemiparesis was recovered over two months following surgery. Tolerable thalamic pain syndrome remained. Here, we report a rare case of thalamic cavernous malformation with a favorable outcome through a contralateral surgical approach.
