Diffuse pulmonary involvement by mycosis fungoides: high-resolution computed tomography and pathologic findings.

摘要

SUMMARY: The authors report the high-resolution computed tomography (HRCT) appearance of diffuse pulmonary involvement by mycosis fungoides in a 74-year-old woman whose clinical and radiographic manifestations simulated pneumonia. The HRCT showed multiple, dense, peribronchovascular nodules with surrounding ground-glass opacity and several wedge-shape peripheral opacities. The autopsy specimen revealed angiocentric and peribronchovascular involvement of mycosis fungoides and pulmonary infarctions distal to angiocentric infiltration of the tumor cells.
