CT and MR imaging showed basal ganglia calcification that appeared as high signal intensity on T1-weighted images of a patient with pseudohypoparathyroidism. MR imaging of an experimental model of calcium phosphate suspensions showed a signal similar to that seen in the patient. Additionally, T1 and T2 relaxation times of the solutions were measured and(More)
Magnetic resonance (MR) imaging and computed tomography (CT) are useful for the evaluation of central nervous system (CNS) lupus. This report describes the use of cranial MR and CT in 21 patients with systemic lupus erythematosus (SLE) with acute neuropsychiatric symptoms manifested by headache, seizures, focal neurological deficits, psychosis, or organic(More)
Peritoneal spread of non-Hodgkin lymphoma is rare: fewer than three percent of persons afflicted with this disease develop peritoneal spread. Pericardial involvement by non-Hodgkin lymphoma is equally rare. We report an instance of peritoneal and pericardial spread in a patient with non-Hodgkin lymphoma that was detected only by CT scan. The peritoneal(More)
Patients with neurofibromatosis have an increased incidence of acoustic neuroma, which is often bilateral. We present three patients with neurofibromatosis and enlarged internal auditory canals secondary to dural ectasia, without associated acoustic neuromata. Air CT cisternography and Metrizamide CT cisternography was needed in differentiating dural(More)
Duplication of the inferior vena cava (IVC) is not an uncommon vascular anomaly. We describe here the appearance of double IVC by radionuclide angiography, computed tomography (CT) scan, and digital angiography. It is important to confirm the presence of duplicated IVC, which is usually first seen on CT scan, because patients undergoing certain surgical(More)
