Successful Infliximab Therapy in a Patient with Refractory Takayasu's Arteritis

Takayasu's arteritis (TA), a granulomatous vasculitis, affects the aorta and its major branches. Glucocorticoids are an effective treatment for patients with active TA, but some patients fail to achieve or maintain remission with the conventional therapy, and side effects resulting from long-term glucocorticoid therapy are potentially serious. Anti-tumor necrosis factor-alpha agents, such as infliximab, may be efficient in patients with refractory TA. We report on a 24-year-old female patient with refractory TA who was treated successfully with infliximab. Clinical remission was induced as determined by repeated 18F-fluoro-2-deoxy-D-glucose positron emission tomography scans combined with assay of serological inflammatory markers.

Massive Hemoptysis due to Endotracheal Hemangioma: A Case Report and Literature Review / 결핵및호흡기질환

Tracheal hemangioma is a rare benign vascular tumor in adults. We reported a case of massive hemoptysis caused by a cavernous hemangioma in a 75-year-old man. This is the first report, to our knowledge, of a tracheal cavernous hemangioma that presented with massive hemoptysis. The lesion was removed with a CO2 laser under rigid laryngoscopy. Endovascular tumors, such as tracheobronchial hemangiomas, should be considered a diagnostic option in cases of massive hemoptysis without a significant underlying lung lesion.

A Case of Delayed Diagnosis of Pulmonary Paragonimiasis due to Improvement after Anti-tuberculosis Therapy / 결핵및호흡기질환

Here, we report a case of pulmonary paragonimiasis that was improved with initial anti-tuberculosis (TB) therapy but confused with reactivated pulmonary TB. A 53-year-old Chinese female presented with a persistent productive cough with foul smelling phlegm and blood streaked sputum. Radiologic findings showed subpleural cavitary consolidation in the right upper lobe (RUL). Bronchoscopic and cytological examination showed no remarkable medical feature. She was diagnosed with smear-negative TB, and her radiologic findings improved after receiving a 6-month anti-TB therapy. The chest CT scans, however, obtained at 4 months after completion of anti-TB therapy showed a newly developed subpleural consolidation in the RUL. She refused pathologic confirmation and was re-treated with anti-TB medication. Nevertheless, her chest CT scans revealed newly developed cavitary nodules at 5 months after re-treatment. She underwent thoracoscopic wedge resection; the pathological examination reported that granuloma caused by Paragonimus westermani. Paragonimiasis should also be considered in patients assessed with smear-negative pulmonary TB.
