The term hemispherectomy refers to the complete removal or functional disconnection of a cerebral hemisphere. The technique was initially developed over 85 years ago to treat infiltrating brain tumors but is now used exclusively for medically refractory epilepsy. Hemispherectomy surgery has progressed from an extremely morbid procedure fraught with complications to a fairly routine one performe...

Two patients at our center experienced florid visual hallucinations following hemispherectomy. Case 1 had intractable left hemisphere focal seizures at 20 months of age from a previous stroke. Following functional hemispherectomy at age 3, he experienced frightening hallucinations 1 month post-operatively for 3.5 months. Case 2 underwent subtotal hemispherectomy at age 6 for intractable focal s...

Commentary Hemispherectomy was introduced by Walter Dandy in 1928 for removal of a right hemispheric glioma (1) but was pioneered for use in catastrophic epilepsy by McKenzie a decade later (2). The procedure was abandoned for years due to its morbidity and mortality but was repopularized in 1950 by Krynauw, who used it to treat infantile hemiplegia (3). The techniques of hemispherectomy then u...

This study examined the effects of parent-implemented mand training on the acquisition of framed manding in a 4-year-old boy who had undergone partial hemispherectomy. Framed manding became the predominant mand form when and only when the intervention was implemented with each preferred toy, but minimal generalization to untrained toys nevertheless occurred. A pure mand test suggested that mand...

Background: The hemispherectomy is a valuable procedure in the management of seizure disorders caused by unilateral hemispheric disease. The anatomical hemispherectomy has been used for this purpose since 1938, however, it was abandoned after reports of postoperative complications caused by superficial hemosiderosis, ependymitis and obstructive hydrocephalus. So that, it has been showed modific...

A patient with hemimegalencephaly and intractable epilepsy underwent a preoperative embolic hemispherectomy. A seizure-free interval of 1 year followed the embolization procedure. In addition, the procedure was thought to be beneficial in limiting blood loss during a subsequent surgical hemispherectomy.

BACKGROUND AND PURPOSE Hemispherectomy is a neurosurgical procedure to treat children with intractable seizures. Postsurgical improvement of cognitive and behavioral functions is observed in children after hemispherectomy suggesting plastic reorganization of the brain. Our aim was to characterize changes in DTI scalars in WM tracts of the remaining hemisphere in children after hemispherectomy, ...

A patient is described who successfully underwent cerebral hemispherectomy for malignant glioma and whose death nine months later, wrongly ascribed to recurrent malignancy, was in fact due to a subsequently-developing benign meningioma in the remaining hemisphere. The possible advantages of a modification of standard hemispherectomy technique are also discussed.

associated with venous angiomatosis of the leptomeninges and ipsilateral, cutaneous facial port-wine stain (facial angiomatosis). Seizures are seen in more than 80% of cases, cognitive impairment in 50% and frequently glaucoma.1-2 Seizures are the result of leptomeningeal angioma and underlying calcifications. These abnormalities are usually considered to be limited to one hemisphere. Frequentl...
