Diagnosis and management of intracranial tuberculomas: about 2 cases and a review of the literature

Abstract

Central nervous system tuberculosis is a major cause of morbidity and mortality in developing countries. Intracranial tuberculoma is rare and is one of the most severe cases of tuberculosis. We present two cases. The first one is about a girl of 7 years, followed for 5 months for lymph nodes tuberculosis on anti-TB treatment that presents generalized tonic-clonic seizures associated with progressive intracranial hypertension syndrome. Brain MRI has objectified necrotic nodules in left hemisphere. The surgical approach of the lesions was direct with complete excision. The diagnosis of tuberculoma was confirmed by anatomopathological examination. The second case is about a 6-year-old girl with no particular medical history, which presents for three months progressive and treatment-resistant cervico-occipital headaches associated with walking difficulties. The MRI objectified left cerebellar tumor process interpreted preoperatively as medulloblastoma. The patient was operated on intraoperative appearance was that of a nodular lesion. Anatomopathological examination confirmed the diagnosis. The intracranial tuberculoma is an unusual variety of the central nervous system tuberculosis and remains a topical issue in Morocco. The prognosis depends on prompt diagnosis, quality of surgical resection and anti-TB treatment. The diagnostic confirmation is histological and should therefore be evoked in front of any intracranial process mimicking a brain tumor.
