Reason: eval for osteo of R cranial bone History: R parietal bone defect The patient is status post right-sided craniotomy. There is a redemonstration of some adjacent dural thickening which was also previously present adjacent to the right temporal lobe. This dural thickening appears to have to be stable compared to the previous exams. It currently measures 30 x 6 mm in axial dimensions.There is a redemonstration of encephalomalacia along the right parietal lobe in the right temporal lobe and right posterior frontal lobeThere is an extra-axial mass adjacent to the medial aspect of the right precentral gyrus which measures 11 x 16 mm coronal dimensions and previously measured 13 x 9 mm coronal dimensions.There is redemonstration of a left-sided extracranial mass currently measuring 15 x 18 mm and previously measuring 17 x 13 mm located adjacent to the the left subcentral lobule.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 right eyeball lens is thin.
1.The patient is status post right-sided craniotomy. The appearance of the craniotomy defect in the adjacent soft tissues is stable. There is no convincing evidence for osteomyelitis at this time.2.There is redemonstration of a two slowly growing extra-axial mass lesions suspected to represent meningiomas. One is located adjacent to the left subcentral lobule and the other one is located adjacent to the right paracentral lobule and precentral gyrus.3.There is encephalomalacia involving right posterior frontal, parietal and posterior superior temporal lobes.
