CTICasesSolitary Pulmonary Capillary Hemangioma
Imaging findings
CT in a patient with a sub-solid nodule in the right lower lobe just over one centimeter in size shows a ground-glass nodule, apparently non-specific and indistinguishable from an adenocarcinoma spectrum lesion. CT-guided core biopsy confirmed a solitary pulmonary capillary hemangioma, histologically composed of dilated vascular channels along the alveolar septa.
Key takeaways
Solitary pulmonary capillary hemangioma is a rare, benign vascular tumor of the lung that presents as a non-specific ground-glass or part-solid nodule on CT, indistinguishable from early adenocarcinoma. The diagnosis requires biopsy with immunohistochemistry demonstrating capillary endothelial staining along alveolar septa.
