Clinical question: Evaluate for postop hemorrhage. Signs and symptoms: Headache. Nonenhanced head CT: Examination demonstrates a surgical cavity in the right frontal lobe containing fluid and air density as well as very minimal blood product. It measures approximately 35 x 36 -mm in size.There is a small focus of high density measuring approximately 4 x 4.5-mm in size suspected of a small acute hematoma immediately lateral to the surgical cavity in the right frontal lobe.Extensive residual surrounding vasogenic edema and very minimal subarachnoid hemorrhage is present. A small residual vasogenic edema in the left frontal lobe is also present and unchanged since prior brain MRI from 5 -- 3 -- 13. The overall mass effect of this finding and resultant midline shift to the left immediately adjacent to the tumor remains fairly similar to preoperative study. Stable normal size of the supratentorial ventricular system and unchanged since prior study.Expected postoperative changes of right frontal craniotomy.
1.Surgical cavity at the site of previously known right frontal lobe tumor with fluid/air and very minimal blood content.2.Minimal subarachnoid hemorrhage in the vicinity of surgical cavity and an approximately 4 x 4.5-mm accurate hematoma lateral to the surgical cavity.3.Postop changes and residual vasogenic edema extensively in the right frontal and minimally in the left frontal and associated mass effect remains similar to prior study.
