Computed tomography was used to guide 55 biopsies on paracardiac masses. The authors' experience, gained with over 800 thoracic biopsies, points to CT as the method of choice for paracardiac masses, especially in those cases where the masses are located close to mediastinal and cardiovascular structures, which are not easily evaluated with fluoroscopy and, therefore, imply a greater bioptic risk. Furthermore, CT allows a more accurate needle trajectory to be selected than fluoroscopic guidance does. A diagnosis was reached in 47 of 55 cases, with 85% diagnostic accuracy. No complications such as hemoptysis, hemothorax, pericarditis and hemopericardium were observed. Only one patient required drainage after pneumothorax.

Fine needle transthoracic aspiration (FNTA) of pulmonary opacities under guidance of computerized tomography (CT) is a simple procedure yielding conclusive results in many patients with malignant lung tumours. The small caliber of the needles utilized and the CT control make this increasingly popular procedure both accurate and safe. Yet a number of complications have occurred; most of them were benign (e.g. pneumothorax) but some were potentially dangerous (e.g. pulmonary haemorrhage), so that the pros and cons of the procedure must carefully be weighed. We report the case of a patient in whom FNTA was complicated by copious haemoptysis and a pulmonary haematoma clearly visible at CT. The literature concerning the potential complications of transthoracic puncture is reviewed.

An analysis of 1,454 percutaneous thin needle biopsies (PTNB) performed in 1,061 patients in the years 1976-1987 disclosed the sensitivity for the detection of malignancy 93.7%, specificity 95.8%, and accuracy 93.9%. The most commonly encountered indication for PTNB was a solitary lung lesion (56% of 1,061 patients), with a rate of true positive cytologic findings 93.4% of patients with proved malignant tumours. Indications for PTNB included pulmonary opacities of or without recognizable segmental distribution, enlargement of mediastinum or hilus, lesions of the pleura or chest wall, and cavitary lesions, with results not significantly worse than in circumscribed peripheral lesions. Pneumothorax occurred in 18%, hemoptysis in 1.9%, other minor complications very rarely. PTNB appears to be a safe, reliable, and accurate technique for diagnosing chest lesions with various types of roentgenographic image.

An unusual case of Campylobacter fetus subspecies fetus bacteremia was presented. A twenty four year old male was admitted to our hospital due to abdominal pain, general malaise, diarrhea, high fever, and hemoptysis. He was alcoholic and fond of eating raw liver. He had a history of partial gastrectomy and disturbance of pancreatic function. He showed pulmonary empyema, pleuritis, thrombophlebitis of lower legs, jaundice, hepatomegaly, diarrhea, pneumothorax, and low T3 low T4 syndrome. C. fetus subsp. fetus was detected from the venus blood and pleural effusion on admission. He was successfully treated by gentamicin, chloramphenicol, and minocycline. This is the fourth case of C. fetus subsp. fetus bacteremia in the Japanese literature. This microanerophilic gram negative curved bacillus has been increasingly associated with human disease and relapsing in nature, so protracted antimicrobial therapy was recommended.

Six years' experience of percutaneous core needle biopsy using the Hausser needle in 502 patients, aged 20-89 years, is reported. A biopsy was carried out when sputum and bronchoscopic methods had failed to establish a definitive histological diagnosis. Over 60% of the lesions were peripheral and about 40% were 2-4 cm in diameter. A correct diagnosis was made by this means in 312 of the 339 patients shown eventually to have a malignant lesion (92%) and in 130 of 146 patients with a benign lesion (89%). A definitive diagnosis was never established in 17 patients. Complications arose in 15% of cases. Pneumothorax occurred in 43 patients (7%), of whom 12 required a chest drain. Further complications included a small haemoptysis (less than 30 ml) in 27 patients (5%), haemothorax necessitating a chest drain in three patients, and an intrapulmonary haematoma in five patients. There were no fatal or permanent complications. Percutaneous core needle biopsy is a valuable procedure with a high diagnostic accuracy in these patients and a low rate of complications.

Lymphangioleiomyomatosis is a rare disease of unknown cause that affects women of reproductive age. It is characterized by progressive proliferation of smooth muscle in the lung. The patients present with progressive shortness of breath, pneumothorax, chylous effusion, and hemoptysis. Four patients with biopsy-proved lymphangioleiomyomatosis of the lung were evaluated using high-resolution CT. In all patients, the scan showed well-defined cystic air spaces, surrounded by uniformly thin walls, distributed diffusely throughout both lungs. The cystic air spaces ranged in size from a few millimeters to 5 cm. Pathologically, these cysts were predominantly bounded by normal-looking parenchymal components, with occasional patchy involvement by a smooth-muscle proliferative process. The CT appearance of lymphangioleiomyomatosis differs quite distinctly from that of other diseases that can cause cystic air spaces, such as fibrosing alveolitis, neurofibromatosis, and bronchiectasis, and less distinctly from pulmonary emphysema and eosinophilic granuloma. Our experience in these few cases suggests that the high-resolution CT findings in lymphangioleiomyomatosis are characteristic of the disease.

To determine the utility of fiberoptic bronchoscopy (FFB) in the short-term evaluation of patients with trauma, we identified 53 consecutive patients (45 male patients; mean age, 36 years) seen over a ten-year period who had FFB performed within the first three days of trauma to the chest and upper airway. There were eight deaths. Fifty patients had blunt trauma to the chest. These were mostly due to motor vehicle accidents (38 patients), crushing injuries (three patients), and falls (three patients). In addition, there were three patients with trauma to the neck. Physical and radiographic findings included pneumothorax (37 patients), subcutaneous emphysema (31), pulmonary contusion (22), hemothorax (21), mediastinal emphysema (16), flail chest (ten), atelectasis (ten), and hemoptysis (five). The FFB was of diagnostic use in 28 patients (53 percent) by revealing complete tracheal transection (one patient), tracheal laceration (three), complete bronchial transection (one), bronchial laceration (two), bronchial contusion (two), ongoing distal hemorrhage/pulmonary contusion (seven), aspirated material (three), mucous plugging/thick secretions (eight), and supraglottic lesions (three). One of the cases of tracheal laceration was not fully appreciated as a complete transection. We conclude that FFB has value in the short-term evaluation of patients with trauma.

Transparietal CT-guided biopsy location can be successfully performed for isolate pulmonary nodules, defined as lesions with a maximal diameter of 3 cm, without any other parenchymal or mediastinal abnormality. A 21 G needle has been used according to an identical protocole in 64 cases (10 benign, 54 malignant). The biopsy was successful in 77.7% of the malignant cases. In relation to the diameter of the nodules, biopsy was successful in 66.7% of the nodules smaller than 2 cm and in 76% of the nodules ranging from 2 to 3 cm. The complications observed were rare (1 case of pneumothorax requiring drainage, 9 cases of pneumothorax without clinical signs and simply followed up, 4 cases of minor hemoptysis requiring no treatment and 5 cases of hematomas smaller than 5 cm on CT).

The thoracic localization of endometriosis may involve the pulmonary pleura and the diaphragm, or the bronchopulmonary parenchyma, according to mechanisms which appear to be quite different. The principal clinical manifestations express themselves depending on their localization, a pneumothorax in the first case and hemoptysis in the second. One clinical characteristic, however, applies to them all, a rhythm strictly related to periods. The current methods of visualization of the pleura enable a macroscopic diagnosis to occur in the former cases in 64% and the body scanner now localizes the second in all cases. Treatment by Danatrol is often strikingly effective in a few months, notably in the cases with parenchymal localization.

We reviewed 35 consecutive cases of post-traumatic pulmonary contusion in children that occurred during a 12-year period. Of these, 19 children (54%) were more than 5 years old, 30 (86%) were involved in motor vehicle accidents, and 29 (83%) had multiple trauma. External thoracic wall contusion, fracture of the bony thorax, tachypnea, hemoptysis, and abnormal breath sounds were frequently absent on presentation. Associated intrathoracic lesions of pleural effusion, pneumothorax, and hemothorax occurred in 20 children (57%) and were particularly prevalent in those with fracture of the bony thorax (93%); the radiographic appearance of these lesions was delayed up to 48 hours in 40% of cases. In 34 children (97%), radiographic evidence of pulmonary contusion was present on admission and did not progress radiographically during hospitalization. No child experienced respiratory deterioration subsequent to presentation or required mechanical ventilation for respiratory insufficiency. Pulmonary contusion in children is usually a consequence of significant-impact injury associated with multiple trauma and has a good prognosis. Despite a paucity of abnormal physical findings, children who sustain high-impact trauma should receive radiographic evaluation of the chest to assess for possible intrathoracic injury. When pulmonary contusion is accompanied by fracture of the bony thorax, serial radiographic evaluation of the chest should be performed during the initial 48 hours of hospitalization.
