MRI appearance of disseminated osseous tuberculosis.

Disseminated osseous tuberculosis is a rare disease. This is a report of two cases of disseminated osseous tuberculosis imaged with MRI at 1.5-T, CT, plain radiography and bone scintigraphy. CT and plain radiography demonstrated either highly destructive or cystic lesions with sclerotic margins. Bone scintigraphy and plain radiography were quite insensitive in detecting areas of involvement compared to MRI. On MRI the abnormal areas had short T-1 relaxation values, which is an atypical appearance for bony infections, and prolonged T-2 relaxation values. The reason for the T-1 relaxation behavior is uncertain. MRI also provided delineation of epidural extent.

Traumatic pericardial hematoma simulating tricuspid valve obstruction.

A large pericardial hematoma caused profound hypoxia, cyanosis, and hypotension in a patient who had sustained trauma in an automobile accident. Angiographic and cardiac catheterization findings suggested intracardiac obstruction at the level of the tricuspid valve. This case emphasizes that localized accumulations of blood or fluid within the pericardial space can simulate intracardiac masses or valve obstruction. Partial pericardiectomy was curative in this patient.
