Diagnosis: Neoplasm of uncertain behavior of brain, unspecified Neoplasm of uncertain behavior of spinal cord.Clinical question: hx craniotomy for lesion : hemangioblastoma. 3 month f/u eval change/recurrenceSigns and Symptoms: none- surveillance The patient status post right suboccipital craniotomy. Since the prior exam a hemorrhagic lesion located in the right cerebellar hemisphere has regressed. It currently measures approximately 10 x 6 mm axial dimensions and previously measured 17 x 16 mm axial dimension. There is no associated contrast enhancement. Since the prior exam edema and mass effect in the right cerebellar hemisphere has regressed significantly.There is redemonstration of a new enlarged perivascular space in the right midbrainNormal 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 status post surgery for right cerebellar mass. This was known to represent a hemangioblastoma. Since the prior exam there has been regression of a right mass and its associated findings. Right cerebellar edema and hemorrhage has regressed. A nodular lesion in the right cerebellar hemisphere has also regressed.
