RESUMO
Taconite, although not classified by the United States Government as asbestos or asbestiform material, has been associated with asbestos-related diseases. The mineral is used in the production of steel and as a road-patch material and is mined in Michigan and Minnesota. This report describes the case of a middle-aged Caucasian woman with exposure to taconite mining dust from her miner father's clothing in childhood with a resultant presentation consistent with asbestosis and intractable pleural pain. Intractable pleural pain has been described in asbestos-exposed patients with theorized etiologies. However, no in vivo reported mechanism has demonstrated a plausible, anatomically apparent mechanism for the pain. We utilize an application of the Vitrea software for enhancement of high-resolution computerized tomography which demonstrates at least one likely mechanism for intractable pleural pain.
