Brain cyst, shunt, headaches, worsening symptoms. Evidence of right-sided hemispherectomy is again seen as well as fragmentation involving the right calvarium related to multiple prior craniotomies. There has been evolution and minimal decrease in size of extra-axial/extra-dural fluid collection along the right cerebral convexity. Unchanged position of catheter is in place spanning from this fluid collection to the left, across the residual left cerebral hemisphere, terminating within the left temporal lobe.A cyst within the anteromedial left temporal lobe measuring approximately 20 x 24 x 12 mm similar to prior previously 21 x 23 x 12 mm. Cysts posterior to the catheter appear similar to prior. A more posterior medial cyst which demonstrates an air-fluid level on 3/9/2016 and demonstrated decrease in size in 3/23/2016 appears to have resolved. Extensive chronic cerebral dysmorphism is unchanged. The white matter surrounding the residual left sided ventricular system remains T2 hyperintense. No new cysts or new mass effect is appreciated.
1.Grossly unchanged catheter traversing the right sided extra-dural fluid collection across to the left temporal lobe. The right-sided extradural fluid collection demonstrates evolution and minimal decrease in size.2.Cysts just anterior and posterior to the lateral aspect of the catheter persist but not clearly changed in size allowing for slight differences in measurement technique. There is a cyst more posteromedially which demonstrated an air-fluid level on 3/9/2016 and some decrease in size on 3/23/2016 which now appears to have resolved.3.Chronic dysmorphism of the brain and sequelae of right hemispherectomy are again seen.
