Magnetic resonance (MR) imaging of the painful ankle of a 15-year-old boy revealed the nidus of a subarticular osteoid osteoma of the talus along with markedly abnormal signal intensity in the neighboring bone marrow. This MR appearance correlated with alterations in the neighboring bone marrow documented by histopathologic examination.
The magnetic resonance appearance of three lesions of focal nodular hyperplasia observed in two patients is reviewed. All three lesions demonstrated isointensity with the liver on the short repetition time (TR) and echo time (TE) spin echo images. One lesion also showed a central area of low signal intensity that pathologically corresponded to a scar. The… (More)
Magnetic resonance (MR) images of the lumbar spine from 150 patients were retrospectively reviewed. In 14 of these patients, at 18 disk levels, a vacuum phenomenon (VP) had been identified on plain radiographs and/or computed tomographic scans. The MR imaging appearance of these gas collections in 17 disks was an area without signal, best seen on spin-echo… (More)
A case of a Morgagni hernia is demonstrated by magnetic resonance imaging (MRI). The correct diagnosis was facilitated by the ability to image directly the anteromedial diaphragmatic defect in the coronal and sagittal planes. The findings from MRI, computed tomography, and radiographic studies are correlated.
Eight adults with known valvular insufficiency were studied with cine magnetic resonance (MR) imaging. Our cine MR uses cardiac synchronization of a rapid small flip angle pulse sequence on a 1.5 T MR system. Eleven regurgitant lesions (including aortic, mitral, and tricuspid valves) were imaged with both cine MR and two-dimensional pulsed Doppler… (More)
Radiologic changes from trauma to the carpus are described. Emphasis is placed upon pathomechanics and characterization of greater and lesser arc injury patterns. Finally, the various posttraumatic instability patterns of the wrist are discussed.
The first case, to our knowledge, of cervicofacial actinomycosis arising in a patient with evidence of infection by the human T-cell lymphotrophic virus type III, the causal agent of the acquired immunodeficiency syndrome, is reported. Clinical uncertainty often exists in cases of actinomycosis due to the relative rarity of the disease, a clinical… (More)
The results of scrotal sonography performed in a recent one-year period (1987) were retrospectively reviewed to assess the role of sonography in the management of patients with extratesticular abnormalities. The study included 226 examinations performed in 204 men. In extratesticular abnormalities, scrotal sonography confirms the clinical impression of the… (More)
A case of an ulcerated, bleeding gastric leiomyoma is presented in which a follow-up UGI examination showed no evidence of residual ulceration within the tumor. Radiologists should be aware that it is occasionally possible to document complete healing of ulceration within a gastric leiomyoma and that conservative medical management may be an alternative… (More)
