title: Calcified intralobar pulmonary sequestration.
abstract: The radiologic features of intralobar pulmonary sequestration (ILPS) have been described and include the identification of a feeding systemic artery on computerized tomography. Radiographically demonstrated calcification is rare and has been described only three times. We describe a patient with an ILPS whose radiographic findings were unusual for two reasons. First, while computed tomography (CT) demonstrated a tubular structure, it did not enhance with contrast material and thus was not considered to be a feeding vessel. Pathological examination revealed that this vessel had undergone thrombosis with subsequent organization and calcification. This finding also explains the second unusual feature, calcification, seen both on a plain chest radiograph and CT.
