“…The MRI features of tuberculomas are distinct from other intramedullary lesions and are reliable enough to start antituberculous therapy. 8 Some of these lesions may resolve completely with antituberculous therapy only, 14 but may expand during chemotherapy. 15 Preoperative antituberculous therapy for 1-2 weeks may avoid spreading of intraoperative tuberculosis.…”

“…With the development of caseation, the centre becomes bright and gives an appearance of 'target sign'. 7,8 The 'target sign' was thought to be a characteristic sign on the radiological image. 5 Sharma et al 5 reported all their lesions showed marked enhancement on gadolinium injection and central hypointensity with peripheral ring enhancement was seen in five out of eight cases.…”

Study design: Case report. Objective: To report a rare lesion of intramedullary cervical tuberculoma. Setting: Department of Neurosurgery, Southwest Hospital, Third Military Medical University, Chongqing, The People's Republic of China. Case report: A 15-year-old boy presented with pain in the neck and shoulder. Examination showed mild left hemiplegia and pinprink hyperalgesia on the left side up to C3 level. Chest X-ray and CT scan showed patch and dot lesions indicating old tuberculous lesions and MRI showed a ring-enhancing intramedullary lesion at C3/4 level. Tuberculoma resection and antituberculous therapy was given. There was satisfactory recovery clinically. Conclusion: Intramedullary cervical tuberculoma is a rare, coexisting systemic tuberculosis and MRI scan helps in obtaining a correct diagnosis; combining surgery with anti-tuberculosis therapy is the treatment of choice.

“…In rare cases, areas of diminished attenuation are seen, which represent caseous necrosis. The latter may be identified as tuberculoma, a nodule with a relatively low signal intensity in comparison with that of other pulmonary nodules on T2-weighted SE or turbo SE images (Sakai et al 1992;Kono et al 1993;Kusumoto et al 1994;Parmar et al 2000;Chung et al 2000;Schaefer et al 2006). In addition, several investigators have reported on typical MR findings of tuberculoma on post-contrast-enhanced T1-weighted images known as "thin-rim enhancement" sign (Sakai et al 1992) (Fig.…”

Since the publication of the Radiologic Diagnostic Oncology Group Report (RDOG) in 1991, the clinical application of pulmonary magnetic resonance (MR) imaging to patients with lung cancer has been limited. MDCT has been much more widely available for staging of lung cancer in clinical situations. Traditionally, FDG-PET or PET/CT is the only modality that reveals biological glucose metabolism of lung cancer, and ventilation and/or perfusion scintigraphy is the only modality that demonstrates pulmonary function. However, recent advances of MR systems and utilization of contrast media make it possible to overcome the limitation of chest MR imaging. Therefore, in the last years, several investigators have demonstrated the significant comprehensive potential of MR imaging to substitute for MDCT and nuclear medicine examinations in lung cancer staging. Currently, MR imaging in lung cancer patients can be applied for (1) detection of pulmonary nodules, (2) characterization of solitary pulmonary nodules, and (3) assessment of TNM classification in routine clinical practice. We believe that further basic studies, as well as clinical applications of newer MR techniques, will play an important role in the future management of patients with lung cancer including MRI.

A healthy 33-year-old man presented with an intramedullary tuberculoma of the thoracic spinal cord manifesting as a 2-month history of progressive paraparesis and sphincter dysfunction. Magnetic resonance imaging showed ring enhancement of the intramedullary thoracic lesion with perifocal edema. General physical examination was unremarkable with no signs of inflammation except for a positive finding by the tuberculin skin test. Total resection of the intramedullary mass was performed through a posterior myelotomy following T11-12 laminectomy. Histological examination revealed a granulomatous lesion that contained Langhans giant cells, inflammatory cells, and caseating necrosis. Acid-fast bacilli staining of the specimens was positive, and cultures grew Mycobacterium tuberculosis. Postoperatively, the paraparesis and sphincter dysfunction improved sufficiently for the patient to return to his ordinary activities. Intramedullary spinal tuberculoma is rare, but must be considered in the differential diagnosis of spinal cord compression.
