Intramedullary tuberculoma (IMT) is considered to be a rare form of spinal tuberculosis (TB). Overall, TB of the central nervous system accounts for approximately 1% of all cases of TB and 50% of these involve the spine. The clinical presentation of spinal intramedullary TB is similar to an intramedullary spinal cord tumor mass. The factors attributable could be malnutrition, poor socioeconomic conditions, and immunodeficiency syndromes. As per the reports, the incidence of primary intramedullary TB is 2 in 100,000 cases among patients with TB. We describe one such patient who presented with progressive asymmetrical paraparesis due to histologically confirmed intraspinal tuberculoma. Paraparesis in spinal IMT is considered to be rare. Hereby, we present the case of a 29-year-old female who presented with asymmetric onset paraparesis of 6 months with associated numbness and tingling began in the left foot 3 months which was ascending in nature. There was no history of stiffness, involuntary movements, flexor spasms, thinning, or fasciculations of muscles. There was a loss of sensation pain, touch, and temperature below L3 with normal reflexes. Power in both the lower limbs was 1/5 as per Medical Research Council (MRC) grading. She underwent a contrast magnetic resonance imaging spine which was suggestive of an intramedullary SOL at D12 vertebral level. The patient underwent surgical intervention with resection of the SOL. Histopathology was confirmed to be an IMT. She was started on Category 1 (antitubercular drugs) and further investigated for primary source, which was found to be negative. We want to emphasize that TB can involve any part of the body. It should be kept as a differential diagnosis of any chronic inflammatory lesion involving the bony skeleton, especially in endemic countries where combined surgical and medical treatment is usually sufficient to provide a cure.

| Introduction | |  |
Tuberculosis (TB) of the central nervous system (CNS) is rare, with an incidence of 0.5%–2% in patients with systemic TB.[1],[2],[3] Pott's disease of the spine (tuberculous spondylitis) is the most common (60%), followed by arachnoiditis (20%), meningitis (12%), and intramedullary lesion (8%). The most common form of spinal intradural TB is meningitis. Intramedullary involvement is rare in TB and usually present in the form of radiculomyelitis, transverse myelitis, intraspinal granulomas, or thrombosis of the anterior spinal artery.[3] Spinal intramedullary TB (SIMT) has a similar presentation as compared to intramedullary spinal cord tumor. When diagnosed in time and managed appropriately, SIMT has a good prognosis.

A 29-year-old female presented with asymmetric onset paraparesis of 6 months. Weakness began initially in the left foot 6 months before admission, followed by the right foot weakness began 2 months later slowly progressing to proximal muscles. Numbness and tingling began in the left foot 3 months ago and ascended proximally. There was no history of stiffness, involuntary movements, flexor spasms, thinning, or fasciculations of muscles. She was able to walk with support earlier; however, she had gradually progressive weakness, leading to walking with support followed by inability to stand with support and was bedridden and with difficulty in sitting and moving on the bed. She had urinary urgency and precipitancy for 2 months without bowel symptoms. There were no symptoms in the upper limbs, chest, or trunk. She denied a history of neck pain, back pain, and root pains. There was no history of significant loss of weight and appetite. She denied a history of systemic illness such as TB and diabetes mellitus. There was no history of exposure to toxins, alcohol intake, fever, or TB.
On examination, she was afebrile with normal vital signs. No hepatosplenomegaly, lymphadenopathy, or spinal deformity was clinically elicited. There was mild atrophy of the left leg and foot muscles; however, both were symmetrical. She has paraparesis (right: proximal 2/5 and distal 0/5; left: proximal 2/5 and distal 0/5). Sensations were impaired below L3. Muscle stretch reflexes were normal in the upper limb and sluggish in the lower limb. The plantar response was flexor on both sides. Cremasteric reflex was absent.
The hematological and biochemical investigations including Vitamin B12 level and tumor markers were normal. Chest X-rays were normal. Magnetic resonance imaging (MRI) of the spine revealed an intramedullary lesion with intense peripheral enhancement and perilesional edema at the D12-L1 level [Figure 1]. She underwent Eleventh thoracic(D11) to first Lumbar(L1) laminectomy.This was followed by posterior midline myelotomy and then total excision of intramedullary granuloma.This granuloma was sent to Histopathology that revealed features of tuberculoma [Figure 2]. She was started on antituberculous therapy and is on follow-up. | Figure 1: T2-weighted image of the axial section of the brain showing a hyperintense subgaleal collection present in the scalp which is in communication with the epidural collection

| Discussion | | |
Lesions from TB may be found in every organ, and CNS is one of the common sites of involvement in the extrapulmonary TB. Tubercular meningitis and cerebral tuberculoma are the most common manifestations of neurotuberculosis. Myelopathy or myeloradiculopathy is the less common presentation in primary intraspinal TB.
TB of the spine causes extramedullary compression and commonly presents with myelopathies.[4] Primary tubercular parenchymal involvement of the spinal cord is uncommon.[1],[4] Intramedullary TB is often associated with pulmonary TB but some cases may present with isolated extrapulmonary form.[5] The higher incidence involving the dorsolumbar area is explained based on the regional blood flow to the spinal cord.[6]
MRI is the preferred investigation to demonstrate the intramedullary lesions including tuberculomas.[7]
Surgical intervention is required in intramedullary tuberculomas for the confirmation of diagnosis and to reduce the granuloma burden.[8] As it is firm and well-circumscribed, it allows surgical removal without significant trauma to the cord. The results of surgical treatment together with antitubercular drugs are a preferred treatment of choice.
