Abstract:
To present CT and clinical features of active tuberculomas, we analyzed retrospectively CT findings of 14 tuberculomas (n=14) in 13 patients which appeared as solitary pulmonary nodules on plain radiographs and evaluated the response of tuberculomas to antituberculous chemotherapy. Nine tuberculomas (64%) were ovoid in shape and 10 (72%) showed smooth margin. Twelve(86%) tuberculomas were shown as low density lesions on unenhanced or enhanced CT scans. Calcification and cavitation were noted in three (21%) and eight (57%) tuberculomas respectively. Seven (50%) tuberculomas were accompanied by satellite nodules. Acid-fast bacilli (AFB) was positive in all tuberculomas in sputum, lavage fluid, or percutaneous transhoracic needle aspiration (PTNA). Smear and culture of lavage fluid and PTNA aspirate were superior to the detection of AFB than sputum examination. Follow-up study with antituberculous chemotherapy in 14 tuberculomas resulted in complete disappearance in three, decrease in size in seven, and no visible change in the remaining four. These observations suggest that tuberculomas are well-defined, ovoid, and low-density nodules containing calcifications and/or cavitations. Tuberculomas are relatively indolent even with threatment.
