A Case of Pulmonary Infarction Probably Related with Henoch-Sch?nlein Purpura

摘要

We report a case of pulmonary infarction probably related with Henoch-Sch?nlein purpura, which presented with purpura on both lower extremities in a 27-year-old woman. The purpura had developed 4 days previously and it had no itching or tend'erness. She complained of mild fatigue, chest tightness, but no dyspnea or hemoptysis. On routine examination, chest radiography showed a poorly defined nodular opacity on the left lung field, and it was diagnosed by a follow up chest CT as a pulmonary infarction secondary to pulmonary vasculitis.
