[Pulmonary cryptococcosis diagnosed by video-assisted thoracoscopic surgery with CT-guided localization: report of a case].

We report a case of pulmonary cryptococcosis diagnosed by video-assisted thoracoscopic surgery (VATS) with CT-guided localization. A 61-year-old man was admitted to our hospital for the precise diagnosis of a solitary mass in the left upper lung. Because the mass was too small to be detected under VATS, we tried CT-guided localization for surgery. One day before VATS, we placed a marking device besides the lesions after percutaneous puncture. We used a Naruke point marker as a marking device. After this procedure, the wedge resection was performed. The pathological diagnosis was cryptococcosis of the lung. The identification of small lesions in the lung has frequently been detected by helical and thin slice CT. Therefore, CT-guided localization procedure may be the most reliable technique to employ before surgery.
