Lesion guided radiofrequency thermocoagulation (L-RFTC) for hypothalamic hamartomas, nodular heterotopias and cortical dysplasias: Review and perspective

Lesion guided radiofrequency thermocoagulation (L-RFTC) via stereotactically inserted coagulation probes is a further development of stereotactic thermocoagulation thalamotomy and stereo-EEG guided RFTC. In this method epileptogenic lesions detected via magnetic resonance imaging (MRI) move to the center of coagulation planning. Two surgical strategies can be applied: lesion disconnection and l...

Hypothalamic hamartoma causing gelastic seizures treated with stereotactic radiofrequency thermocoagulation.

PURPOSE To present a case of small hypothalamic hamartoma (HH) causing gelastic seizures and treated with stereotactic radiofrequency thermocoagulation. CASE REPORT A 22-year-old man presented with intractable gelastic seizures and focal seizures refractory to medical treatment. Magnetic resonance imaging showed a 6 mm x 6 mm x 7 mm sessile intraventricular HH. Under local anesthesia, four in...

Comment from Professor Dirk Van Roost on: Lesion-focused stereotactic thermo-coagulation of focal cortical dysplasia II-B: A new approach to epilepsy surgery?

The idea of attempting to eliminate epileptogenic foci by stereotactic means is not novel; it has been pursued since the 1960s. A range of ablation techniques has been used: from simple electrocoagulation to thermo-coupled electrocoagulation or radiosurgery, and, most recently, focused ultrasound. If the results of stereotactic treatment for epilepsy surgery have not been completely convincing ...

Hypothalamic Hamartomas: Two Cases

This is a MRI study of two patients presented with history of gelastic seizures since many years ago. Plain and post intravenous gadolinium multiplanar MRI imaging of the brain is performed. It showed well-defined non-enhancing mass lesions in the region of hypothalamus and tuber cinereum. It showed signal intensity similar to the gray matter and imaging diagnosis of hypothalamic hamartoma is m...

Schizencephaly and nonlissencephalic cortical dysplasias.

The refinements of neuroimaging have brought to the fo reground a wealth of conditions that were previously the restricted domain of clinical neuropathology. This fascinating (and often bewildering) harvest, includes primary malformations and intrauterine disruptions of the brain. To the first category belong chromosomal abnormalities and genetic or cryptogenic malformations. The latter categor...
