Cerebral necrosis simulating an intraparenchymal tumor.
Cerebral necrosis after radiation therapy of extracranial neoplasms is an infrequent but well-documented complication [1-5]. CT and MR findings associated with changes caused by radiation therapy have been reported; however, differentiating changes caused by irradiation from postoperative changes and recurrent tumor may not always be possible because the·CT and MR findings are nonspecific [6-8]...
متن کاملHemifacial spasm associated with intraparenchymal brain stem tumor.
Hemifacial spasm (HFS) is characterized by paroxysmal bursts of involuntary clonic and tonic activity in muscles innervated by the facial nerve. Idiopathic HFS is hypothesized to be a result of microvascular compression of the facial nerve at its root exit zone in the brain stem. Symptomatic (secondary) HFS is usually caused by compression of the facial nerve’s root exit zone. Whether HFS can a...
متن کاملNavigation-guided endoscopic biopsy for intraparenchymal brain tumor.
To evaluate the efficacy of intraparenchymal brain tumor biopsy using endoscopy and a navigation system (navigation-guided endoscopic biopsy) as a diagnostic tool, a case series of intraparenchymal tumor biopsies was reviewed. Navigation-guided endoscopic biopsy was applied in 9 cases, stereotactic needle biopsy in 16 cases, and open biopsy with or without navigation system in 34 cases. In all ...
متن کاملAn overview of therapeutic approaches to brain tumor stem cells
Primary and secondary malignant central nervous system (CNS) tumors are devastating invasive tumors able to give rise to many kinds of differentiated tumor cells. Glioblastoma multiform (GBM), is the most malignant brain tumor, in which its growth and persistence depend on cancer stem cells with enhanced DNA damage repair program that also induces recurrence and resists current chemo- and radi...
متن کاملIntraparenchymal Brain Malignant Fibrous Histiocytoma
A 60-year-old man, with a history of hypercholesterolemia and left leg deep vein thrombosis, was admitted to hospital following two weeks of headaches and expressive aphasia. Neurological examination confirmed expressive aphasia in the absence of motor, sensory or cranial nerve deficit. A total body computer tomography (CT) imaging showed a single intraparenchymal lesion with a central necrotic...
