A case report of isolated brainstem tuberculoma without any focal neuologic deficit.
CASE REPORT: A 7yr. old female child presented with complaints of headache since 3 days, vomitings since 3 days. Severe headache all over the head. Vomitings are present and are non-bilious non-projectile. Developmental history normal appropriate for the age. Immunization history followed national immunization schedule. BCG scar present. No past history of tuberculosis or other significant history. No family h/o tuberculosis. On general examination child is concious, irritable. Vitals are normal. No cranial nerve palsy. On motor system examination power, bulk, tone normal no focal neurologic deficit. No involuntary movements. No sensory loss. No autonomic distubances. No signs of menigeal irritation. Skull and spine normal. Gait normal. On MRI scan there is solitary tubercular granuloma present at level of pons. Fundoscopy normal, no optic disc edema. The TST is reactive (12mm). Chest X Ray is normal.
DISCUSSION: In developing countries, the incidence of brain tuberculoma constitutes 5-40% of intracranial SOL. (1) Lesions are most often singular but may be multiple. Isolated brainstem tuberculomas are rare, accounting for 2.5-8% of all intracranial tuberculomas. (2) Isolated tuberculomas presenting as mass lesions in the brain stem without evidence of tuberculous involvement of any other system or other parts of the CNS, are distinctly rare. (3) it has been reported that the predominant locations of tuberculoma are supratentorial in adults and infratentorial in children. (4) the most common symptoms are headache, fever, focal neurologic findings, and convulsions. The TST is usually reactive, but the chest radiograph is usually normal. On CT or MRI of the brain, tuberculomas usually appear as discrete lesions with a significant amount of surrounding edema. Contrast medium enhancement is often impressive and can result in a ring-like lesion.
Vimla et al 15 reported a 12 year old patient, who presented with isolated "1 1/2% syndrome". (5) Piyush Gautam et al reported Isolated Pontine Tuberculoma Presenting as Horizontal Gaze Palsy. (6) In our case there no neurological deficit except severe headache and vomitings. Important and clinically interesting and significant observation is there is an evidence of paradoxic expansion the lesions may occur some times and may lead to worsening the clinical condition. (7) This paradoxic response usually occurs during first 3 months from the start of therapy. (8) Corticosteroids therapy should be given and ATT should be continued.
CONCLUSION: Isolated brainstem tuberculosis is very rare presentation. Important thing to be remember is there is chance of paradoxic enlargement of the lesion or may be appearance of new lesions may occur due to enhancement of immuneresponse during the treatment. And it is not an indication of stopping treatment.
