An Ancillary CT Finding of Intrapulmonary Solitary Fibrous Tumor: A Case Report

Solitary fibrous tumors are benign or malignant neoplasms originating from mesothelial and submesothelial cells that most frequently occur in the pleura, but they may also occur at various extrapleural sites (1, 2). Intrapulmonary solitary fibrous tumors are extremely rare and may present as well-defined, round or ovoid nodules on computed tomography (CT) scan, leading to widely differing imaging diagnoses including hamartomas and carcinoid tumors (2, 3). We report herein a rare case of intrapulmonary solitary fibrous tumor that showed typical features on enhanced chest CT scan, and we also provide a helpful ancillary CT finding for the diagnosis of intrapulmonary solitary fibrous tumor.
