Dear Editor,

West syndrome is an electroclinical syndrome with a combination of spasms in clusters and hypsarrhythmia in electroencephalography (EEG). Development delay at onset is not a necessary criteria for West syndrome.[1] It is associated with various neurocutaneous syndromes such as tuberous sclerosis complex (TSC), Sturge– Weber syndrome More Details, linear nevus sebaceous syndrome, neurofibromatosis-1, hypomelanosis of Ito, and incontinentia pigmenti. It is also well known that children with West syndrome and tuberous sclerosis are prone to develop autism spectrum disorder. Here we report a 6-month-old girl who presented to us as West Syndrome, but on clinical examination she was found to have features suggestive of a overlap of TSC and Klippel–Trenaunay syndrome (KTS).


   Case Report Top


A 6-month-old girl presented with mild development delay and infantile spasms since 3 months of age. The frequency was 2–3 spasms/cluster and 2–3 clusters/day. The prenatal and perinatal period was uneventful. No significant family history was observed. Examination revealed multiple ash leaf spots over left arm, right leg, and buttocks [Figure 1]C. She also had a pink-red blotchy stain over right upper limb extending to chest and back [Figure 1]A. Also, there was visible hypertrophy of the right upper and lower limbs [Figure 1]B. Rest of the systemic and neurological examination was normal. Magnetic resonance imaging (MRI) of brain revealed multiple cortical tubers and subependymal nodules (SEN) with calcification [Figure 2]A and B. Echocardiography and abdominal ultrasound were normal. EEG was suggestive of hypsarrhythmia. In view of multiple tubers, SEN, and ash leaf spots (three major criteria for TSC), and right hemihypertrophy and port-wine stain (two of the classic triad of KTS), a diagnosis of TSC with KTS overlap was made. She was initiated on vigabatrin with which the spasms became passive.

   Discussion Top


Infantile spasms can occur either in isolation or in clusters. If they occur in clusters and EEG shows hypsarrhythmia, it is called as West syndrome. Infantile spasms occur in up to 68% of children with TSC. Overlap of these two neurocutaneous syndromes has not been described till now. TSC and KTS are believed to be inherited separately. However, TSC has been infrequently associated with limb hypertrophy and vascular anomalies. This is probably due to the dysregulation of phosphoinositide 3-kinase (PI3K)–Akt–mTOR (mammalian target of rapamycin) cascade, leading to increased cellular growth and differentiation.[2] Despite frequent dysregulation of this cascade in TSC, the association of TSC and KTS is rare due to variable expressivity.[3],[4],[5] Hence, mTOR inhibition may play a key role in the management of this association. Hence, whenever an infant presents with infantile spasms, one must look for neurocutaneous markers, as the management and prognosis differs.

To conclude, this is the first case in literature, to the best of our knowledge, showing the overlap of TSC and KTS along with West syndrome in an infant.
