We report a case of trochlear nerve palsy that was the sole initial sign of an aneurysm of the superior cerebellar artery. A craniotomy confirmed the anatomical compression of the trochlear nerve by this aneurysm. The clipping of the aneurysm resulted in the resolution of the trochlear nerve palsy.
Forty patients with cervical radiculopathy were examined preoperatively with magnetic resonance imaging (MRI). MRI was used alone in 27 (68%) of the 40 patients; the remainder also had computed tomography in conjunction with myelography. The primary criterion on MRI for a clinically significant lesion was asymmetrical narrowing of the subarachnoid space in… (More)
Nineteen patients were examined for cervical spondylotic myelopathy with magnetic resonance imaging. Pre- and postoperative magnetic resonance scans were obtained in most cases. Surgical confirmation of the pathological condition was obtained for all 19 patients. On the T2-weighted scans, there was increased signal intensity within the spinal cord at the… (More)
