Percutaneous drainage of tuberculous iliopsoas abscesses under image guidance.

Most intra-abdominal and other types of fluid collections are now successfully drained percutaneously under image guidance. The utility of percutaneous drainage of tuberculous abscesses, especially those associated with osseous changes, is, however, less well established. Six patients with tuberculous iliopsoas abscesses were successfully managed by percutaneous drainage combined with antituberculous therapy. The abscesses were bilateral in one patient and unilateral in the other five. Drainage was by needle aspiration under ultrasound (US) guidance in one patient, and by catheter under CT guidance in the other patients. Three patients had associated osseous changes. There were no procedural complications. Tuberculous iliopsoas abscess can be successfully treated by percutaneous drainage and appropriate antituberculous therapy.

Pulmonary tuberculosis presenting as mass lesions and simulating neoplasms in adults.

In a review of the chest X-rays and medical records of 597 cases of culture- or biopsy-proven pulmonary tuberculosis (PTB; age range 1.5-72 years), seen over a period of 6 years (1991-97), 26 patients had radiographic patterns unusual for PTB. These patterns were mass-like densities simulating neoplasms, chronic lower lobe airspace opacities without adenopathy, mediastinal adenopathy without parenchymal airspace opacities and bronchopleural fistula without other radiographic abnormalities. The most common of these unusual radiographic patterns was mass-like densities, most of which were initially and mistakenly diagnosed as neoplasms. These masses, seen in 11 adult patients, form the basis of this report. Two children aged 1.5 and 2 years also had tuberculous mass densities initially diagnosed as neurogenic tumour and round pneumonia, respectively. They have been excluded from the present series, and form the subject of another report. The masses were lower lobe predominant and were not usually associated with fibro-productive satellite lesions or with calcification or cavitation. In view of the recent resurgence of PTB and the importance of chest X-rays in its diagnosis and management, this rare radiographic pattern needs to be emphasized.

Renal papillary necrosis in Kuwait.

In 2,158 consecutive routine urograms, 85 patients (51 males and 34 females) were found to have typical changes of renal papillary necrosis, an incidence of 3.9% (2.8% in males, 9.4% in females). The changes were bilateral in 60 patients (71.6%) and unilateral in 25 (29.4%). 3 patients were diabetics, 4 had sickle cell anaemia and 7 had obstructive uropathy. 19 patients admitted to analgesic abuse. The remaining 52 patients were idiopathic but a combination of analgesic abuse and dehydration may have been the cause in this group. The possible reasons for the high incidence of RPN especially in females in this hot desert environment are discussed. The literature on the subject is briefly reviewed.
