On the T2 images, the tumor appears remarkably well-demarcated from the surrounding brain . Furthermore, one can appreciated that the tumor is actually located within the ventricle. The clinical presentation is one of complex partial seizures , with stereotypic gastrointestinal symptoms, deja vu, and smells. Limbic involvement is also manifested as rage attacks. In addition, the remarkable paucity of neurologic deficit with the degree of mass effect suggests a slowly growing, ie, low-grade lesion.
Surgical resection is indicated.
With the patient under satisfactory general endotracheal anaesthesia, head held in three point fixation and turned toward the right side, the patient's head was prepped and draped in the usual fashion and a question mark incision was made over the left zygoma. Raney clips were placed on the skin edge. The temporalis muscle was divided along the superior temporal line and along the posterior margin of the incision down to the zygomatic arch. The muscle was incised for 1 cm anteriorly along the arch. The flap was dissected subperiosteally padded with sponges and retracted with stay hooks.
