Novel epileptogenic positive rolandic sharp waves in an adult: an unusual case of post-hypoxic myoclonus

Post-hypoxic myoclonus (PHM), a common consequence of cardiac arrest and anoxic brain injury, is broadly divided into the entities of myoclonic status epilepticus (MSE) and Lance-Adams syndrome (LAS) [1]. MSE and LAS are differentiated on the grounds of clinical and electroencephalographic (EEG) findings, with distinction between the two entities carrying important prognostic information. Here we report a unique case of PHM where our patient defied classification into either MSE or LAS, but whose PHM was instead a continuous myoclonic seizure correlating to epileptogenic positive rolandic sharp waves (PRS) on EEG.
