We report a patient with fatal acute arsenic poisoning presenting as vomiting and diarrhea with the finding of intra-abdominal radiopacities on radiographs. These represent the classic features of acute arsenic toxicity and are detailed here as a reminder to others facing a similar puzzling patient with this potentially treatable poisoning.

Vasculitis is a clinical-pathological process characterized by inflammation and necrosis of blood vessels. It has been effectively classified by Fauci. Granulomatosis in the lung may be angiocentric or bronchocentric in distribution. ⋯ Because the radiology of these diseases can be similar, their important differences are highlighted. The appearance of multiple nodules, often with cavities, and pleural-based consolidations resembling pulmonary infarcts should suggest pulmonary angiitis and granulomatosis, especially if improvement occurs in one area while disease is progressing elsewhere. Bronchocentric granulomatosis is not a primary vasculitis but is discussed because of its similarity to the other diseases.

We report a patient with a traumatic lung cyst, documenting its radiological evolution: the formation of the pneumatocele, the appearance posteriorly of an intracavitary hematoma, and the spontaneous resolution of the radiological abnormalities.
