Female, 31 years old, status post craniotomy for tumor resection. Postoperative findings are seen compatible with recent right frontal craniotomy and right frontal lobe resection. The right-sided dura is mildly thickened and enhancing. The resection cavity is roughly wedge shaped and contains fluid and air.Restricted diffusion is seen along the margins of the resection cavity. A small amount of ragged-appearing tissue is evident within the anterior aspect of the resection cavity but this is nonspecific. Most of the nodular enhancing tissue seen on the preoperative examination has been resected, especially superiorly. Along the inferior posterior aspect of the cavity, however, there remains a region of thickened tissue which contains patchy foci of enhancement appearing similar to prior.Elsewhere in the brain, periventricular T2 hyperintensity, predominantly at the level of the frontal horns, is again seen, a finding which may be related to prior therapy. No new signal abnormality or pathologic enhancement is detected. No new abnormal extra-axial fluid collections are seen. The right frontal horn remains partially effaced similar to prior, while the remainder of the ventricular system is unremarkable.
Expected findings are seen status post right frontal resection. Most of the nodular enhancing tissue evident on the preoperative examination has been resected, particularly along the superior aspect of the cavity. Along the posterior inferior aspect of the cavity, there does remain some nodular parenchymal thickening which contains patchy foci of enhancement.
