1/5. Primary hemangiopericytoma of lung: radiography and pathology.

    Two cases of primary hemangiopericytoma of the lung are reported. The massive tumors had radiographic features of round or oval contour, homogeneous opacity, well circumscribed smooth outline without calcification, and no compression of the surrounding lung tissue. They were rather homogeneous histologically, well encapsulated, and centrally located, but extended peripherally by replacement, instead of compression, of the pulmonary parenchyma. review of the literature about 34 other cases suggests these are the usual characteristics of primary hemangiopericytomas of the lungs.

2/5. Thoracic splenosis diagnosed by fine-needle aspiration cytology: a case report.

    A case of thoracic splenosis diagnosed by fine-needle aspiration (FNA) of subpleural lung lesions is presented. The patient, a 49-yr-old male with a history of gunshot wound to his trunk with splenic rupture and splenectomy several years previously, presented with recent hemoptysis and multiple subpleural solid nodules shown in the left lung field by CT scan. As the possibility of a metastatic malignancy vs. mesothelioma was entertained, an FNA was performed on one of these lesions, revealing lymphoid tissue with abundant vascularity simulating the structure of splenic tissue. In view of this finding, supported by the absence of splenic outline in the CT radiograph, the diagnosis of splenosis was made. This is the fourth reported case of thoracic splenosis in which FNA cytology was utilized for diagnosis, yet the first in which the diagnosis was based exclusively on the FNA cytologic findings. Clinical, pathologic, and diagnostic aspects of this entity are discussed.

3/5. Massive pulmonary hemorrhage from dual circulation pulmonary arteriovenous malformations in hereditary hemorrhagic telangiectasia.

    Pulmonary arteriovenous malformations (AVMs) are commonly supplied by the pulmonary arterial system and rarely by the systemic bronchial circulation. The authors outline the case of a young woman with pulmonary AVMs as part of hereditary hemorrhagic telangiectasia with the uncommon presentation of massive hemoptysis. Management of her recurrent, life-threatening pulmonary hemorrhage was complicated by pulmonary AVMs that were supplied by both the pulmonary and systemic bronchial arterial circulatory systems. Transcatheter embolotherapy of the higher pressure bronchial systemic circuit was necessary for acute hemostasis.

4/5. Control of hemoptysis: systemic angiography and anastomoses of the internal mammary artery.

    Twenty-three patients with massive and recurrent hemoptysis were examined with angiography. Particular attention was directed to the internal mammary arteries. Specific causes for the bleeding were tuberculosis (n = 9), aspergilloma (n = 8), bronchiectasis (n = 1), primary systemic amyloidosis (n = 1), congenital and acquired pulmonary venous obstruction (n = 2), chronic pulmonary embolism (n = 1), and bilateral congenital pulmonary artery stenosis (n = 1). Eleven of these 23 patients were treated with systemic arterial embolization, and immediate cessation of bleeding occurred in nine. The recognition of the numerous collateral vessels and anastomoses of the internal mammary arteries is essential for successful percutaneous embolization for hemoptysis. The authors outline these various pathways and collateral vessels.

5/5. Modification of minitracheostomy technique to limit bleeding complications.

    Minitracheostomy is a commonly performed procedure usually carried out by junior medical staff. Though there are few problems associated with the technique of minitracheostomy, bleeding is often encountered. We now present a brief case report demonstrating the problems associated with bleeding. We also outline an alteration in insertion technique with the 'Minitrach' designed to diminish the risks of serious bleeding, and report on our results with this technical modification.
