[Neuroradiologic manifestations of central nervous system tuberculosis in 122 adults].
La Revue de Médecine Interne 2003 Februrary
PURPOSE: Central nervous system (CNS) tuberculosis remains a public health problem, particularly in developing countries. The aim of this study is to characterize neuroradiologic findings of various intracranial lesions.
METHODS: We retrospectively reviewed data of 122 patients with CNS tuberculosis, without immunosuppression. CT scan was performed in all patients, whereas 17 patients had CT scan and MRI.
RESULTS: We included 74 women (61%) and 48 men (39%) with a mean age of 37 years (17 -88y). 18 patients (14,7%) had a history of tuberculosis. Tuberculous meningitis was the most frequent clinical presentation (119 cases). Mycobacterium tuberculosis was isolated in cerebrospinal fluid of 18 patients (15%). Several types of lesions were identified : hydrocephalus (35 cases), tuberculomas (29 cases), leptomeningitis (26 cases), infarction (15 cases), abcesses (2 cases). Hydrocephalus was associated to other lesions in 26 cases. Communication hydrocephalus was present in 28 cases. Multiple tuberculomas were seen in 23 cases (80%), with miliary aspects in some cases. In 3 cases, tuberculoma was present without meningitis. Patients with leptomeningitis showed thick meningeal contrast enhancement involving all basal cisterns. Infarction resulted from arterial englobement or embols, and involved the area of middle cerebral artery (12 cases).
CONCLUSION: Central nervous system tuberculosis has different appearences, mostly hydrocephalus and tuberculomas. MR with contrast is necessary for diagnosis and for follow-up during treatment.
