Hemorrhage after CT-guided percutaneous needle biopsy: a case report

Hemorrhage is one of the common complications of CT-guided percutaneous needle biopsy. We present a case of a young woman with an incidental lung mass at the right lower lobe. The woman was observed of severe intrathoracic hemorrhage after CT-guided biopsy. She was finally diagnosed as von willebrand disease, a rare hereditary hemorrhagic disease, and the lung mass was diagnosed as intrapulmonary solitary fibrous tumor, another rare mesenchymal neoplasm with very few references in the literature.
