Female, 28 years old, status post craniotomy. Evaluate postoperative cyst fenestration and catheter placement. Fragmentation of the right calvarium is again seen compatible with multiple prior craniotomies. Findings are also redemonstrated compatible with right hemispherectomy.A presumably extradural fluid collection is seen within and along the right craniotomy containing an air-fluid level. The thickness of this fluid has decreased when compared to the prior examination. A catheter is in place spanning from this fluid collection to the left, across the residual left cerebral hemisphere, along or through the left thalamus, terminating within the left temporal lobe.A cyst within the anteromedial left temporal lobe, just anterior to the catheter, is unchanged in size. Two cysts are also seen posterior to the catheter. The more lateral of these cysts is unchanged in size. The more medial cyst is smaller and no longer contains an air-fluid level as on the prior examination.Extensive chronic cerebral dysmorphism is unchanged. The white matter surrounding the residual left sided ventricular system remains T2 hyperintense.
1.A catheter is in place traversing the residual left cerebral hemisphere, spanning from the right sided extradural fluid collection across to the left temporal lobe.2.A cyst which is anterior to the catheter, within the anteromedial left temporal lobe, is unchanged in size. One cyst posterior to the catheter is unchanged in size, while the other cyst posterior to the catheter is smaller.3.The extradural fluid collection along the right craniotomy defect is decreased in size as well.4.Chronic dysmorphism of the brain and sequelae of right hemispherectomy are unchanged.
