en Neurosurgery Neurosurgery case report case report <p>  </p><p> <strong> Abstract </strong></p><p>  The Intraparenchymal schwannomas are very rare tumors with only 52 reported </p><p>  cases . We describe a 38 years old man with eight months history of poorly controlled </p><p>  seizures despite of medical therapy. On brain CT scan a 1.5 x 1.5 cm hypodense enhancing lesion was seen in right posterior-inferior frontal lobe. On brain MRI the lesion </p><p>  was hypointense in T1 and hyperintense in T2 with homogenous enhancement after contrast injection. He underwent localized craniotomy and total excision of the tumor. The tumor was completely covered by brain cortex and well demarcated with fleshy consistency and grayish color. After histopathologic examination and Immunohistichemical staining, diagnosis of the schwannoma was established. During 6 </p><p>  months period of follow up no seizure was reported by the patient. </p><p>  </p> schwannoma, intraparenchymal, frontal lobe 112 116 http://mjiri.iums.ac.ir/browse.php?a_code=A-10-1-70&slc_lang=en&sid=1 Mansour Parvaresh-Rizi m_parvaresh@yahoo.com, 2003194753284600856 2003194753284600856 Yes Department of Neurosurgery, Iran University of Medical Sciences, Tehran,Iran Seyed Ebrahim Hejazian 2003194753284600988 2003194753284600988 No Department of Neurosurgery, Iran University of Medical Sciences, Tehran, Iran.
