A 54-year-old woman was admitted for cough, sputum, and an abnormal chest X-ray shadow. Bronchoscopy showed mucoid impaction of the bronchi (MIB). Histopathologic evidence of mucous plugs was consistent with one component of allergic bronchopulmonary mycosis. Schizophyllum commune (S. commune) was identified. Two attempts at removal of the mucous plugs were(More)
Adenovirus pneumonias are reported relatively commonly in pediatric or immunocompromised patients, but the clinical presentation of adenovirus pneumonia in immunocompetent hosts is not well known. We treated an immunocompetent 42-year-old man with mild adenovirus pneumonia following pharyngitis and conjunctivitis. Diagnosis was established on the basis of(More)
A 20-year-old man was referred to our hospital due to hemoptysis. Chest CT showed a ground-glass opacity, suggesting pulmonary bleeding; however, a diagnosis was not obtained. At a follow-up examination after 2 months, Chest CT showed improvement of the ground-glass opacity, however a cavitary nodule had newly appeared. Four months later, another new nodule(More)
A 57-year old man with desquamative interstitial pneumonia (DIP) showed a marked increase in eosinophils in the bronchoalveolar lavage (BAL) fluid. The patient was referred to our hospital for abnormal shadows on his chest X-ray with no symptoms in May 2007. Computed tomography (CT) showed patchy, peripheral predominate ground-glass opacity. The BAL fluid(More)
An 80-year-old woman presenting with fever and cough was given a diagnosis of community-acquired pneumonia. She was hospitalized and treated with ampicillin/sulbactam (ABPC/SBT) and clarithromycin (CAM). Gram stain images and sputum culture results led us to believe that the causative agent was Haemophilus influenzae. Drug sensitivity testing indicated that(More)

A 75-year-old man with chronic gastritis and gastro-esophageal regurgitation syndrome was admitted to our hospital complaining of continuous productive cough, and an abnormal shadow was noted on a chest X-ray film.

A 17-year-old-man developed left-sided pneumothorax in 1995. Chest computed tomography (CT) showed a thick-walled cavity in the left lower lobe. Video-assisted thoracic surgery was performed, and pathologic findings of the resected lung showed a cavity, organizing hematoma, and a fibrous nodule. Fragility of connective tissue was suspected, and biochemical(More)
A 51-year-old woman visited our hospital with chief complaints of cough and fever. A chest X-ray detected an abnormal shadow in the right lung field. A chest computed tomography scan showed solid consolidation at S10 of the right lung. A blood test revealed elevated levels of the tumor markers, CEA(12.1 ng/ml), SLX (134 U/ml) and CA19-9 (76.2 U/ml).(More)
