   Abstract 


Tuberculous meningitis rarely causes refractory epilepsy and is a rare cause of West syndrome. We describe three infants, who had tuberculous meningitis complicated by stroke and paradoxical tuberculoma, and, who later developed West syndrome.

   Introduction Top


West syndrome is catastrophic epilepsy of infancy and childhood characterized by a triad of epileptic spasms, hypsarrythmia, and developmental retardation.[1] Tuberculous meningitis (TBM) is a rare cause of West syndrome.[2],[3] Timely diagnosis and early initiation of treatment are crucial to morbidity and mortality in both TBM and West syndrome. We describe three infants with TBM and West syndrome.


   Case Descriptions Top


Out of 289 children with TBM in our institute from January 2011 to August 2015, three children developed West syndrome. The diagnosis of TBM was based on the clinical symptoms suggestive of TBM (fever >5 days with or without headache, vomiting, focal deficits and/or encephalopathy, suggestive neuroradiology for TBM, suggestive cerebrospinal fluid, and/or evidence of extracranial tuberculosis). The children with West syndrome were treated with corticosteroids and followed up for outcome assessment [Table 1]. All children had basal exudates and hydrocephalous at diagnosis. Cerebrospinal fluid analysis of all three children was consistent with TBM. However, acid-fast bacilli were not isolated in any children. These children developed epileptic spasms after 3–14 months of TBM diagnosis. All three children had developmental delay and epilepsy on follow-up.

Multiple ring-enhancing lesions are seen in the right sylvian fissure suggestive of tuberculoma (curved arrow)

(D) MRI T2-weighted image showing hyperintensity in right lentiform nucleus (arrow) suggestive of chronic infarct. These areas were hypointense in corresponding T1-weighted images (not shown). These tuberculomas reduced significantly (E) and were calcified (E and F) after 3 years of therapy

   Discussion Top


These cases highlight that epileptic spasms can complicate the course of TBM. The latency of epileptic spasms varies from 4 to 24 months following the neurological insult.[4] This latency depends on various factors such as severity of brain injury and age at insult. The initial insult results in pathological processes such as gliosis and abnormal synaptic reorganization. Infantile TBM is frequently complicated by progressive hydrocephalous and secondary neuronal injury, progressive meningovasculitis leading to infarcts, and paradoxical tuberculoma as in index cases, which contribute to epileptogenesis in TBM.[5]

There are only few reports of epileptic spasms in TBM. A 10-month-old girl with focal infantile spasm due to underlying cerebral tuberculoma has been described.[2] Zorn-Olexa et al.[3] described a child with TBM (with tuberculoma) who initially presented with refractory status epilepticus and subsequently refractory infantile spasm. The etiology was multifactorial with infarcts, tuberculomas, and paradoxical tuberculomas. Watanabe et al.[6] described a 10-month-old infant with TBM who presented with status epilepticus and developed spasms 3 months later. Thus, these cases highlight the multifactorial origin wherein stroke, porencephaly, and paradoxical tuberculoma contribute to refractory epilepsy in TBM.

Refractory epilepsy is an uncommon complication with TBM. In a series, 10% of children had epilepsy, 75% of seizures in TBM were controlled with only one antiepileptic drug, and 25% required two antiepileptic drugs.[7] Epileptic spasms, as in our report, may be a marker for poorer developmental outcomes and possibly, for refractory epilepsy in children recovering from TBM.


   Conclusion Top


West syndrome can rarely be seen in children recovering from TBM. Its occurrence may be a marker for poorer developmental outcomes and possibly, for refractory epilepsy in these children.
