- posterior right gyrus rectus encephalomalacia with herniation of part of gyrus through the defect with an intact meningeal lined sac of CSF protruding into the sinus cavity.
Case Discussion
Planum sphenoidale defect with sinus communication of neuroparenchyma can occur in sinus surgeries. In particular, they may occur during middle turbinectomy and uncinectomy depending on the anatomic configuration of the latter. This may result in CSF rhinorrhoea, and should be brought to the attention of the ENT surgeon, for urgent planum sphenoidale repair, as life threatening cranial spread of infection can occur.
