Recent partial resection of a pituitary tumor. There are recent postoperative findings related to left frontal craniotomy for debulking of a sellar and suprasellar mass, which is unchanged in size overall. There is high T2 and intermediate to high T1 signal hemorrhage surrounding and primarily within the remaining suprasellar portion of the tumor, which appears similar in extent as on the recent CT, accounting for differences in technique. There is extensive confluent vasogenic edema and up to 15 mm of midline shift to the right. Apparent restricted diffusion along the surgical margins is likely attributable to the underlying susceptibility effect from hemorrhage rather than actual ischemia. The ventricular system appears unchanged, with partial effacement of the left lateral ventricle and mild dilatation of the right lateral ventricle. The skull, with a markedly expanded sella appears unchanged. The left subgaleal fluid collection appears to be slightly larger, measuring up to 20 mm in thickness, previously 15 mm.
1. Recent postoperative findings related to left frontal craniotomy for debulking of a sellar and suprasellar mass, which is unchanged in size. Likewise, the acute hemorrhage surrounding and primarily within the remaining suprasellar portion of the tumor appears to be similar in extent as on the recent CT, accounting for differences in technique. 2. Unchanged vasogenic edema and up to 15 mm of midline shift to the right. 3. The ventricular system appears unchanged.4. The left subgaleal fluid collection appears to have increased in size.
