RESUMO
A solitary tuberculous brain lesion (STBL) can be difficult to distinguish from a glioma, metastasis or other infectious disease, especially from a pyogenic brain abscess. We analyzed the clinical characteristics, diagnostic procedures and outcomes of 24 patients with STBL diagnosed in three centers from France, India and Mexico. We also reviewed 92 STBL cases previously reported in the literature. General symptoms were found in 54% of our patients, including enlarged lymph nodes in 20%. Cerebrospinal fluid was typically abnormal, with lymphocytic pleocytosis and a high protein level. The lung CT scan was abnormal in 56% of patients, showing lymphadenopathy or pachipleuritis. Brain MRI or CT was always abnormal, showing contrast-enhanced lesions. Typically, MRI abnormalities were hypointense on T1-weighted sequences, while T2-weighted sequences showed both a peripheral hypersignal and a central hyposignal. The diagnosis was documented microbiologically or supported histologically in 71% of cases. Clinical outcome was good in 83% of cases.

Endometriosis involving the neural axis is extremely rare. A twenty-five-year-old woman presented with acute onset paraparesis with bladder involvement of five-day duration. We missed her history of cyclical back-ache related to menses at the emergency room. Magnetic resonance imaging (MRI) of spinal cord showed an intramedullary tumour with bleeding at conus-epiconus level. She was operated in the emergency department with laminectomy-durotomy and tumour decompression. Histopathology of the tumour was suggested endometriosis.
