A 60 years old male presented with ripple like movement (myokymia) over the right thigh and back pain of 10 years duration. Neurological examination revealed myokymia, mild wasting and weakness of right quadriceps. Deep tendon jerks were normal. There was no sensory deficit. Straight leg raising test was negative. Gadolinium enhanced MRI showed conus cauda junction mixed intensity tumour [Figure 1]. No other intra spinal developmental anomaly was detected. At surgery soft to firm tumour attached to conus was excised. Thick whitish pultaceous material was removed. Histopathology showed atrophic keratinised stratified squamous epithelium and masses of mature tissue elements like sebaceous glands, smooth muscle bundles, malenophanges and fibrous tissue suggestive of cystic teratoma [Figure 2]. Subsequently the symptoms completely resolved. Conus medullaris teratoma, pr`esenting as myokymia is very rare.
