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.
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)
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)
We have described a case of cystic adenomatoid malformation of the lung, detected before birth. The ultrasound findings demonstrated in this case correlated well with both the radiographic appearance of the lesion and with the gross pathology. Though we do not feel that the ultrasonic findings described are specific for this entity, they are believed to be… (More)
A case report is presented in which malfunction of a peritoneovenous shunt was caused by subintimal dissection of the venous end of the shunt tubing. The radionuclide shunt patency study demonstrated a collection of radioactivity at the venous end of the tubing, representing the abnormal intramural collection of peritoneal fluid. Scintigraphic demonstration… (More)
The CT scans of a woman with left flank and lower abdominal pain were interpreted as showing a mass adjacent to the tail of the pancreas. Imaging with Tc-99m sulfur colloid and emission computerized tomography revealed that the CT scan abnormality represented functioning splenic tissue and thereby avoided unnecessary surgical exploration.
