44 years Female (DOB:9/24/1972)Reason: stroke? Chiari? History: HAsPROVIDER/ATTENDING NAME: JAMES A. MASTRIANNI JAMES A. MASTRIANNI The CSF spaces are appropriate for the patient's stated age with no midline shift. The cerebellar tonsils are low lying and extend 4 mm below the level of the foramen magnum. They are not pointed.The marrow of the skull and skull base and visualized upper cervical spine is predominantly lower signal which is a nonspecific finding.No abnormal mass lesions are appreciated intracranially. No intracranial hemorrhage is identified. No edema is identified within the brain parenchyma.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.
1.The cerebellar tonsils are low lying and borderline for Chiari I malformation.2.In general there is a mottled appearance to the visualized marrow structures including upper cervical spine and skull base and calvarium. This is nonspecific and could be within the range of normal at this age. Low marrow signal can be seen with chronic disease, anemia, lymphoproliferative disorder, myeloproliferative disorder. It is a nonspecific finding
