Pulmonary artery sarcoma: diagnosis and postoperative follow-up with gadolinium-diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging.
Pulmonary artery sarcomas are infrequently encountered and are often misdiagnosed before surgical exploration or autopsy. On clinical examination and conventional imaging studies, they are frequently mistaken for pulmonary emboli. To our knowledge, this case report is the first to describe the postoperative magnetic resonance imaging (MRI) appearance of residual disease of a pulmonary artery sarcoma and to assess the potential usefulness of MRI for monitoring such lesions postoperatively. Contrast-enhanced MRI, a relatively noninvasive method, seems well suited for postsurgical follow-up of pulmonary artery sarcomas.

Posterior longitudinal ligament ossification myelopathy and hypothyroidism.
Two elderly white women with a long history of hypothyroidism and myelopathy showed ossification in posterior longitudinal ligament at their cervical spine. Case histories are presented and the reported association of PLLO with other conditions discussed.

MRI for evaluation of perianal inflammation.
BACKGROUND: We describe the value of using magnetic resonance imaging (MRI) in six distinct clinical settings often encountered in cases of perirectal inflammatory disease. METHODS: MRI was performed on six patients with known perianal inflammatory disease; the number, anatomic extent, location, and signal intensities of various lesions and their associated complications were assessed. RESULTS: MRI is a noninvasive technique that is useful in the diagnosis and management of perirectal inflammatory disease. CONCLUSIONS: In patients with known fistulas, MRI may determine the lesion's anatomic extent, localize unsuspected fistulas, and confirm or exclude the inflammation of the fistulous tract(s). Information obtained by MRI examination may, in turn, be used to determine treatment of patients with perirectal inflammatory lesions and can be a useful adjunct in following results of therapy.

A review of tibial spine fractures in bicycle injury.
Nine tibial spine fractures were studied. Three of these nine cases included younger patients who fell from a bicycle and sustained an isolated avulsion fracture of the tibial spine. In all three cases, the medial tibial spines of the right knees were fractured. The other remaining five medial tibial fractures included two motorcycle and two automobile accidents, together with one basketball injury. One of the nine tibial spine fractures involved the lateral tibial spine.
