Hemangiopericytoma - An extremely rare bronchial tumour, a difficult diagnosis
European Respiratory Journal, 2012Co-Authors: Ruxandra Ulmeanu, Ramona Nedelcu, Dalia Manolache, Radu Matache, Dan Ioan Ulmeanu, Andrada Florian, Radu Stoica, Oana Deleanu, Doina Boiculese, Florin MihaltanAbstract:Background: Hemangiopericytoma is a rare mesenchymal Tumor originating from the capillary pericytes (about 1% of vascular Tumors). Its primary localization in the lung is extremely rare. Case presentation: A 52year old man, smoker(60PY), is diagnosed two months ago-by bronchoscopy and chest CT scan-with the main left Bronchus Tumor with subsequent negative biopsies. He was admitted to our hospital for reconsideration and clarification endoscopic diagnosis. "Encefaloidal" endoscopic Tumor that stenosis left main Bronchus from the begining by 65%, but without bronchial wall infiltration around the Tumor. 1.We performed rigid bronchoscopy and “Jet”ventilation with snare electroresection of Tumor in three stages. Histopathological examination of a biopsy specimens - non-small carcinoma. After bronchoscopy intervention, persist only distal total obstruction of left main Bronchus. 2. Radical left pneumonectomy with mediastinal lymphadenectomy and intrapericardial approach of vessels is involved. Macroscopically : white multinodular Tumor, 14/10/10cm size, with large foci of necrosis. Microscopically : malignant hemangiopericytoma Discussion : Diagnosis of hemangiopericytoma was established after left pneumonectomy. Postoperative chemotherapy that combined carboplatin and taxol were performed. Conclusion : Hemangiopericytoma is a rare vascular slow-growing Tumor with high local recurrence and poor prognosis because the recurrence of disease. Preoperative diagnosis is difficult. Surgical radical excision is the treatment of choice, although the criteria for determining the area of resection have not been established.

Diagnosis and staging using spiral computed tomography of an endobronchial carcinoid Tumor
JBR-BTR : organe de la Societe royale belge de radiologie (SRBR) = orgaan van de Koninklijke Belgische Vereniging voor Radiologie (KBVR), 2000Co-Authors: B Coulier, M MairesseAbstract:The authors emphasize the effectiveness of spiral CT in the diagnosis of typical endobronchial carcinoid. The Tumor was found in a 25-year-old man referred for evaluation of steroid-resistant asthma. Successful diagnosis and complete local staging of the right intermediate Bronchus Tumor were obtained by two successive single apnea spiral acquisitions: a high resolution series (HRCT) with Multiplanar Reconstruction (MPR) and 3D virtual endoscopic views was completed by a dynamic angiographic series (angio-CT) with multiplanar Maximal Intensity Projections (MIP). The CT findings are compared with macroscopic anatomic views and major features of bronchial carcinoid are shortly addressed.

A case of primary cystic mediastinal hemangiopericytoma.
Archives of pathology & laboratory medicine, 1994Co-Authors: Tomohiro Osanai, Takemichi Kanazawa, K Nakamura, T Tsushima, M Kimura, Kogo OnoderaAbstract:We describe a 35-year-old man with a primary cystic mediastinal hemangiopericytoma who presented with the complaint of progressive dysphagia for 6 months. The computed tomography and magnetic resonance imaging findings revealed that a well-defined, fluid-filled mass (measuring approximately 10 x 10 cm) was located posterior to the heart and inferior to the carina of the Bronchus. Tumor puncture showed translucent yellow fluid with normal concentrations of carcinoembryonic antigen, squamous cell carcinoma-related antigen, and carbohydrate antigen 19-9 and a high concentration of carbohydrate antigen 125. After removal of the Tumor, microscopic examination revealed a malignant hemangiopericytoma. To our knowledge, this is the first case of a primary mediastinal hemangiopericytoma with cystic formation. Moreover, we showed the specific biochemical findings of the cystic fluid that were useful for differentiation from other cystic mediastinal Tumors.
