Introduction: Spinal intramedullary tuberculoma (IMTB) is a rare disease that accounts for 1 to 2/100,000 patients with tuberculosis [1]. This case demonstrated that this patient had atypical presentations compared to common tuberculosis considering that IMTB cases are really rare.
Case presentation: A 19-year-old male presenting with back pain and weakness of both lower limbs, which started in the left lower limb and subsequently involved the right lower limb for three months. He had sensory impairment below T6 and hypoesthesia. He complained of urine hesitancy and a feeling of incomplete voiding of urine. He was on anti-tubercular treatment (ATT) for last two months. MRI exhibited hypointense portion on T1-weighted images. T2-weighted image also showed hypointensity at T6, which suggested for intramedullary mass. Excisional biopsy was suggestive for tuberculoma.
Discussion: In TB-endemic country like in Indonesia, tuberculoma should be considered as a differential diagnosis for intramedullary SOL irrespective of age or presence of extra-cranial focus of TB. MRI is the optimal tool for evaluating and diagnosing IMTB at an early stage and useful in follow-up. However, IMTB imaging characteristics may vary with immune response of individual or the stage of the tuberculoma formation [3]. The aim of early surgery is to decompress the spinal cord and achieve improvement in neurological function.
Conclusion: This case was reported to emphasize that early surgical decompression is required as a delay might cause damage to the spinal cord. This case also provides some evidences based data, thus contributing to the future research studies and clinical practice.
