Case of tracheal diverticulum and bronchiectasis

Tracheal diverticulum is a rarely encountered entity usually diagnosed incidentally on CT scan. It may be asymptomatic or may present with recurrent respiratory infections or other symptomatology. Here we report a 59-year-old baker presented with shortness of breath, cough, and sputum production that had tracheal diverticulum in association with bronchiectasis on HRCT which has rarely been reported in the literature

Mediastinal lymphangioma in a child

We report a case of a male child with a cystic mass in his left side of the neck with extension to the mediastinum. This article highlights the clinical and paraclinical findings and management of these cases. In conclusion, it is necessary to evaluate the mediastinum for extension of the cyst in cases with cystic hygromas of the neck. Surgical resection of the tumor through a cervical incision can be considered

Pheochromocytoma crisis due to glucocorticoid administration: a case report and review of the literature

We report a patient who presented with two episodes of severe hypertension after intramuscular injection of betamethasone. The first attack was associated with pulmonary edema, while the second attack was associated with high anion gap metabolic acidosis, renal failure, hyperglycemia, and hypokalemia. The attacks led to the diagnosis of pheochromocytoma, which was confirmed by appropriate diagnostic tests. The tumor was excised successfully and the patient is presently asymptomatic. We believe that these episodes were initiated by glucocorticoid injection, an event reported in a few cases. We briefly review potential mechanisms resulted in hypertensive crisis in such patients

Malignant mesothelioma: a study of sixty-six cases

This study was conducted to review the epidemiology, and biochemical data of pleural fluid to assess the potential contribution to occupational risk of patients with malignant mesothelioma [MM] in Iran. Hospital files of patients with MM of the pleura in Masih Daneshvari Hospital were reviewed between 1997 and 2004 and were evaluated in a cross-sectional study. 66 patients [49 men and 17 women] with a mean age of 53.8 +/- 4.2 yrs were selected. Probable or known occupational contacts were detected in 8 [12.1%] patients. The diagnosis was confirmed by closed pleural biopsy in 26[39.4%] cases. Statistical analysis showed significant cut-off for LDH and glucose level in pleural fluid analysis. Detailed occupational history must not overemphasize blind biopsy as the first diagnostic approach for MM of pleura and pleural fluid glucose as well as LDH had characteristic levels respectively
