Intrapulmonary solitary fibrous tumor is extremely rare. A few reports have presented typical CT findings such as well-defined, variable"”sized, heterogeneously or homogenously well-enhanced intrapulmonary nodules. We report herein a rare case of intrapulmonary solitary fibrous tumor that showed typical clinical and CT features, and we also provide an ancillary CT finding that shows a distinguishable tubular vascular structure within the nodule. The tubular vascular structure was conjoined to the proximal pulmonary vein. In this study, we highlight an ancillary CT finding reported for the first time for the diagnosis of a patient with intrapulmonary solitary fibrous tumor.

  • Fig. 1 A 64-year-old woman with intrapulmonary solitary fibrous tumor. Sequential enhanced chest CT scans (A-D) demonstrate a well-defined, ovoid nodule in the right lower lobe with heterogeneous enhancement and it has a distinguishable tubular vascular structure (arrows). The tubular vascular structure is conjoined to the right proximal pulmonary vein. CT = computed tomography

  • Fig. 2 Pathological findings of the tumor. A. A uniformly hypercellular tumor shows dilated and divided vessels, a staghorn configuration (hematoxylin and eosin stain, × 40). B. Spindle cells show a patternless pattern, an indistinct cellular margin, round to oval nuclei and short dense collagen fibers (hematoxylin and eosin stain, × 200).
