History:
Clinical signs:
Early symptoms: Partial epileptic seizure with sensitive manifestation, progressing into generalized grand mal. Diagnostic interpretation: symptomatic epilepsy.
CT, MR: large frontoparietal expansion with atypical calcifications in the right hemisphere. Slight edema. Small tumorous lesion in the right orbita.
Neurological examination: clumsiness of the left hand, weak upper left extremity, Dufour's sign positive on the left, left sided dysdiadochokinesis.
Hematological, biochemical a mikrobiological examinations, x-ray of the lungs and ultrasound examination of the abdomen revealed no pathology.
Surgery: frame less stereonavigation. Electrodes for neurophysiological monitoring were applied. Craniotomy was performed. Dura mater was streched by edema. Transdural stimulation showed motoric activity of the face, head and upper right extremity. Durotomy was performed at the area of ventral part of tumorous infiltrations. Cortical stimulation with response. Within the zone with no response corticotomy was performed (5×3 cm) and partial resection of the tumor was performed.
The surgery was followed by partial epileptic seizures, 2× generalized. Moreover Jackson's paroxysms on the left were observed as well. The seizures were succesfully treated by increased level of antiepileptic medication.
Follow-up CT of the brain: iatrogenic pneumocephalus; the appearance of the tumor is without changes.
Therapy by Temodal (temozolomid) combined with radiotherapy was initiated.

Histology:
Diffuse/fibillar astrocytoma with transition into anaplastic astrocytoma. Moreover the component of anaplastic oligodendroglioma is present as well.
2nd reading: mixed glioma with predominance of oligodendroglial component (WHO grade 2) with minor admixture of anaplastic astrocytoma (WHO grade 3). Because of proliferation (proliferative index 6 – 10%) and anaplastic areas the case was signed up as anaplastic oligoastrocytoma grade 3.
