Successful third surgery for a case of status gelasticus: lessons learned after nearly 200 cases of hypothalamic hamartoma surgical resection.

We report the case of a 3-year-old boy with status gelasticus symptomatic to a giant hypothalamic hamartoma despite two previous hypothalamic hamartoma surgeries using pterional approaches from each side. Following his third resection employing an endoscopic, transventricular approach, he has been seizure free for 6 months with significant cognitive, behavioral, and electroencephalographic improvement. This case reinforces the importance of surgery for a form of status epilepticus and in addition that repeat (three) surgeries can be successful, indeed life changing. The optimal surgical approaches and management plan for hypothalamic hamartoma surgery-including subtemporal, subfrontal, transcallosal, and endoscopic approaches-are discussed, including how these treatment decisions have evolved as a result of our large series experience.
