[Intralobar Sequestration Associated with Aneurysm of the Aberrant Artery and Aspergillus Infection: Report of a Case].

A 32-year-old man was referred to our department for surgery because of recurrent pneumonia. Aspergillus fumigatus was detected in his sputum culture at the first visit. We started antifungal therapy one month before surgery. His chest radiograph showed an infiltrative shadow in the right lower lobe, and chest computed tomography (CT) showed an infiltrative shadow and large and small cystic changes in the right lower lobe. CT angiography (CTA) revealed two anomalous arteries supplied by the aorta that drained into the right lower lobe. An aneurysm with a diameter of 25 mm had formed in one anomalous artery. Based on these findings, intralobar pulmonary sequestration with Aspergillus infection and an anomalous artery forming an aneurysm was diagnosed. In addition, we embolized the aneurysm of the anomalous artery. After embolization, right lower lobectomy was safely performed. The patient was discharged on the 15th post-operative day with no complications.

[Müllerian Cyst of the Posterior Mediastinum].

Müllerian cyst is rarely reported in the literature. Here, we reported a rare case of Müllerian cyst of the posterior mediastinum. The patient was a 46-year-old woman who was found to have an abnormal shadow on chest X-ray film at medical examination and was followed up as suspected of bronchogenic cyst. One year later, the lesion increased and she was referred to our hospital for surgery. Chest computed tomography demonstrated a 36 mm diameter cystic tumor in front of the right 4~5 thoracic vertebra level. We performed thoracoscopic surgery for diagnosis and treatment. Histopathological examination revealed that the cyst wall was covered with a layer of columnar epithelium. In addition, the estrogen receptor was found to be positive in the epithelia by immnunohistology and the pathological diagnosis was a Müllerian cyst. Müllerian cyst have been reported in the literature to be associated with gynecological disorders or obesity. The present case was found to have ovarian enlargement, which has been carefully followed up.

[Lung Cancer with Multiple Cavitation and Ground Glass Opacity;Report of a Case].

A 81-year-old man was referred to our hospital because of cough and fever. Chest computed tomography(CT) showed multiple cavitation and ground glass opacity in the right lower lobe. Antibiotic treatment was effective in the improvement of the infiltrative shadow and the inflammatory reaction. After 1 year, bronchoscopy was performed because the shadow remained on the following chest CT, and the adenocarcinoma of the lung was found. A lower lobectomy of the right lung was performed.
