A Case of Pulmonary Actinomycosis Associated With Aspiration of Cedar Leaves.

The aspiration of foreign bodies may induce various infectious diseases, including actinomycosis, and its association with foreign bodies has been reported. We encountered a patient who developed Actinomyces-induced lung abscess associated with aspiration of cedar leaves. The patient was a 56-year-old Japanese woman who aspirated decorative cedar leaves contained in a lunch box while eating a meal, and coughing and bloody phlegm occurred thereafter.

Postobstructive pulmonary edema that developed immediately after the removal of an endobronchial foreign body.

The patient was a 5-year-old boy who was transported to our hospital for a paroxysmal cough, disturbance of consciousness, tonic-clonic convulsions and labored breathing. The patient's respiratory failure persisted after the convulsions remitted, and the presence of an endobronchial foreign body was suspected based on the findings of chest CT performed the following day. A peanut was subsequently removed from the right main bronchus using a bronchoscope with tracheal intubation and bag valve mask ventilation.

Hemothorax with a high carbohydrate antigen 19-9 level caused by a bronchogenic cyst.

A 58-year-old man presented with right-sided chest pain. Radiography and computed tomography showed a pleural effusion in the right chest and a mass in the right hilum. Thoracentesis showed a hemothorax.

CT-guided ultrathin bronchoscopy: bioptic approach and factors in predicting diagnosis.

Background: The diagnostic sensitivity of current bronchoscopy for peripheral lung cancer is inadequate because the bronchoscope insertion range is limited and confirmation of the position of the biopsy apparatus at the lesion under X-ray fluoroscopy is inaccurate. The combination of ultrathin bronchoscopy and computed tomography (CT) is effective for solving these problems.

Objective: This study was a retrospective study analyzing prospectively collected data to identify factors contributing to the diagnosis and the appropriate biopsy method in CT-guided ultrathin bronchoscopy for peripheral lung cancer.

Diagnosis of peripheral pulmonary lesions using a bronchoscope insertion guidance system combined with endobronchial ultrasonography with a guide sheath.

We developed a bronchoscope insertion guidance system that produces virtual images by extracting the bronchi by automatic threshold adjustment, and searching for the bronchial route to the determined target. We used this system in combination with a thin bronchoscope and endobronchial ultrasonography with a guide sheath (EBUS-GS), and evaluated its practicability, usefulness and safety. The subjects were 31 patients with 32 peripheral pulmonary lesions.

A virtual bronchoscopic navigation system for pulmonary peripheral lesions.

Study Objectives: We performed ultrathin bronchoscopy for pulmonary peripheral lesions using a system that displays virtual bronchoscopy (VB) images to the lesion simultaneously with actual images and navigates the bronchoscope to the target bronchus. We then evaluated the system with regard to its usefulness and problems.

Design: A pilot study.

A barium marking method using an ultrathin bronchoscope with virtual bronchoscopic navigation.

CT scanning in a 77-year-old woman showed a ground-glass opacity pattern shadow(9 x 7 mm) in the right lower lobe. To allow identification of the location of the lesion during thoracoscopic surgery, preoperative barium marking was performed using an ultrathin bronchoscope and virtual bronchoscopic navigation. Virtual bronchoscopy was performed based on thin-section CT images, and virtual bronchoscopic images to the target sites were obtained.

CT scanning of a 77-year-old woman showed a ground-glass opacity pattern shadow (9 x 7 mm) in the lower lobe of the right lung. To allow identification of the location of the lesion during thoracoscopic surgery, preoperative barium marking was performed using an ultrathin bronchoscope and virtual bronchoscopic navigation. Virtual bronchoscopy was performed based on thin-section CT images, and virtual bronchoscopic images to the target sites were obtained.

[CT-guided transbronchial diagnosis using ultrathin bronchoscope for small peripheral pulmonary lesions].

We performed computed tomography (CT)-guided transbronchial diagnosis on 23 patients, using an ultrathin bronchoscope (external diameter, 2.8 mm) for small peripheral pulmonary lesions (< or = 2 cm). The mean size of the lesions was 1.
