Tubular retractor-assisted minimally invasive parafascicular approach for dermoid cyst.

ABSTRACT: Intracranial dermoid cysts are benign lesions that may be diagnosed incidentally or present symptomatically due to mass effect-focal neurological deficits, seizures and/or hydrocephalus-or chemical meningitis secondary to spontaneous rupture. The use of tubular retractors in minimally invasive parafascicular surgery (tsMIPS) has been described extensively as a technique to preserve neurological function whilst safely maximizing the extent of resection. The authors present the first use of the tsMIPS approach for removal of a dermoid cyst in a 68-year-old female who presented with abulia and seizures due to a large Sylvian fissure dermoid cyst. This approach minimized trauma to surrounding cortical-subcortical structures, as supported by connectome analyses, without sacrificing visualizatio
