A 38-year-old man presented with a 2-month history of progressive leg pain. An x-ray film of both tibial bones showed multiple osteolysis. At the same time, nasal polyps were present. A biopsy of the tibial bone remained unclear. A carcinoma was not found. A biopsy of the nasal polyps revealed a Rosai-Dorfman-Destombes disease.
Constrictive pericarditis is a relatively rare clinical manifestation nowadays. We present the case of an HIV-positive patient with constrictive calcified pericarditis due to an infection with Mycobacterium tuberculosis. Pericardectomy was performed. The therapeutical approach is discussed and the literature is reviewed.
Left recurrent laryngeal nerve palsy usually results from invasion or compression of the nerve caused by diseases localized within the aortopulmonary window. This study reports the case of a 76-yr-old male with vocal cord paralysis due to lymph node involvement by silicosis. This rare entity was identified by video-mediastinoscopy, which revealed a granulomatous and fibrosed recurrent lymph node encasing the nerve. The nerve was dissected and released from scar tissues. Progressive clinical improvement was observed followed by total and durable recovery of the voice after 15 weeks follow-up.
We describe a young snowboarder suffering from dyspnea, chest pain and dysphagia following a blunt chest injury. These symptoms were caused by an accident-related hemorrhage within a preexisting lymphangioma of the right posterior mediastinum. At the same time a lymphangioma of the left anterior mediastinum was found. The lymphangioma of the posterior mediastinum was resected through a right posterolateral thoracotomy after thoracoscopy had demonstrated that a complete resection could not be performed on this way. The lymphangioma of the left side was resected 4 month later by a left-sided hemiclamshell approach due to its size and localisation. Complications arising from mediastinal lymphangioma are described as compression, infection, spontaneous bleeding, rupture and chylothorax. This is the first description of a posttraumatic, symptomatic hemorrhage within a mediastinal lymphangioma.
Deformity of the forehead is usually the first clinical presentation of the abnormally enlarged paranasal sinuses caused by pneumosinus dilatans. The diagnosis and surgical treatment of two cases are reported. The type of osteotomy described is recommended as a method of surgical treatment of this condition.
