Endobronchial metastasis.

Endobronchial metastases from nonpulmonary neoplasms are rare. Since 1971, we have treated 23 patients with endobronchial metastases, the findings for which form the basis of this article. Many types of primary tumors are capable of endobronchial metastases, although breast, colon, and renal carcinomas predominate. The mean time from the diagnosis of the primary carcinoma to the diagnosis of endobronchial metastases was 59.9 months. Bronchoscopic results were diagnostic in all cases. Although the mean time for the appearance of endobronchial metastases is almost 5 years, on examination the majority of patients will have symptomatic extrabronchial metastatic disease, the quality of their survival will often be poor, and their survival time will be limited (12.5 months). Surgical resection should be confined to patients with localized disease.

Surgical resection of a solitary liver metastasis in a 46-year-old patient with a malignant thymoma.

Clinical history, surgical treatment, and pathologic findings of a solitary liver metastasis of a malignant thymoma in a 46-year-old female are reported. An extensive literature review has revealed no record of surgical resection of liver metastasis in a patient with invasive thymoma.

Mediastinal involvement by alveolar rhabdomyosarcoma: evaluation with computerized tomography.

We have reported a case of alveolar rhabdomyosarcoma with mediastinal involvement occurring in a 15-year-old boy. Computerized tomography revealed an anterior mediastinal mass with internal mammary nodal involvement, which had metastasized from a tumor of the abdominal wall musculature. When making the differential diagnosis of a mediastinal mass with concurrent distant soft tissue and muscle involvement in an adolescent, rhabdomyosarcoma should be considered.

Splenic abscess as a complication of septic yersinia: CT evaluation.

Yersinia enterocolitica (YE) frequently causes gastrointestinal illness, but is rarely a cause of systemic infection. The complications of septic YE include a wide variety of extraintestinal manifestations, with a 34-50% mortality rate. We present a patient with septic YE complicated by a splenic abscess. The clinical presentation was nonspecific, and the diagnosis of splenic abscess was made by computed tomography (CT). Because of the nonspecific clinical presentation and the wide range of extraintestinal manifestations of septic YE, CT can prove helpful in the diagnosis and management of these patients.

Acute pulmonary hemorrhage. CT evaluation.

The computed tomography (CT) scans and chest radiograph of seven patients with bronchoscopic or pathologically proven cases of pulmonary hemorrhage were reviewed to determine the appearance and value of each modality. CT revealed the presence and location in all cases while chest radiographs were falsely negative in two cases. The CT pattern was always an alveolar pattern while the pattern was more variable on chest radiographs. By providing better pattern definition than the chest radiographs, CT is the study of choice in detecting the presence of a suspected pulmonary hemorrhage.
