Pulmonary hemorrhage in patients with systemic lupus erythematosus.

Five patients with pulmonary hemorrhage associated with SLE were studied. Chest radiographs showed extensive alveolar opacity immediately after hemoptysis or dyspnea in four patients. In one patient an interstitial pattern seen initially progressed rapidly to an alveolar pattern.

Venous angioma treated by radiation.

A case of cerebral venous angioma which disappeared completely after local irradiation of 3200 cGy is presented. This new method is considered to be beneficial for the treatment of venous angiomas, particularly to prevent rebleeding from them.

Wallerian degeneration of the corticospinal tract in the brain stem: MR imaging.

Magnetic resonance imaging (MRI) of wallerian degeneration of the corticospinal tract in the brain stem was studied in 25 patients with chronic supratentorial vascular accidents. In the relatively early stages, at least three months after ictus, increased signal intensities in axial T2-weighted images--with or without decreased signal intensities in axial T1-weighted images--were observed in the brain stem ipsilaterally. In later stages, at least six months after ictus, shrinkage of the brain stem ipsilaterally--with or without decreased signal intensities--was clearly observed in axial T1-weighted images.

[MR imaging of brainstem infarction].

Thirty-three patients with old brainstem infarct were studied with MR imaging at 1.5T. T1-weighted images were most useful for diagnosing brainstem infarct.
