Diagnosis: Malignant neoplasm of frontal lobeClinical question: Eval for recurrence of PXA s/p RT.Signs and Symptoms: PXA.Comments: Pt w/ PXA s/p complete resection and focal RT. | The CSF spaces are appropriate for the patient's stated age with no midline shift. The patient is status post left frontal craniotomy for left frontal lobe surgery. There is a small linear focus of enhancement present along the inferior medial aspect of the resection site which is stable compared to prior exam. There is also small focus of T1 signal hyperintensity adjacent to the frontal horn of left lateral ventricle. Perfusion imaging does not demonstrate any areas of trabecular vascularity. The signal characteristics of the apparent fluid within the resection cavity are slightly different from that of spinal fluid.Normal vascular flow voids are present in the distal carotid and vertebral arteries, the basilar artery and the proximal anterior, middle and posterior cerebral arteries as well as the internal cerebral veins and superior sagittal sinus.The visualized portions of the paranasal sinuses are clear. The visualized portions of the mastoid air cells are clear. The visualized portions of the orbits are intact.
The patient is status post left frontal lobe surgery. The appearance of the resection site is stable compared to the prior exam. Small focus of enhancement at the surgical site remains stable. It is quite possible that it is related to postoperative effect.
