[Gliomatosis cerebri: the diagnostic potential of MRT]
1Abteilung für Röntgendiagnostik und Nuklearmedizin, Städt, Krankenhaus München-Bogenhausen.
Abstract:
Gliomatosis cerebri is a rare tumor of neuroepithelial origin in middle aged persons presented by deterioration of cognitive functions, psychomotor retardation and cerebral convulsions. MRI predominantly shows a bilateral and diffuse infiltration of midline adjacent brain structures including medulla. Areas with focal anaplasia occasionally reveal an accumulation of contrast media. The diffuse tumor manifestation requires a differentiation from encephalitis and demyelinating diseases with a similar distribution pattern of lesions. Three cases have been examined. In conclusion the performance of MRI including control and brain biopsy are indicated to establish an in vivo diagnosis.
Insights
Gliomatosis cerebri, a rare brain tumor, presents with cognitive decline and seizures. MRI and biopsy are crucial for diagnosing this diffuse neuroepithelial tumor.
Area of Science:
- Neuropathology
- Neuroradiology
Background:
- Gliomatosis cerebri is a rare neuroepithelial tumor affecting middle-aged individuals.
- It is characterized by cognitive deterioration, psychomotor retardation, and cerebral convulsions.
Observation:
- Magnetic Resonance Imaging (MRI) typically reveals bilateral, diffuse infiltration of midline brain structures, including the medulla.
- Focal anaplastic areas may show contrast enhancement.
- The diffuse nature of gliomatosis cerebri necessitates differentiation from conditions like encephalitis and demyelinating diseases.
Findings:
- Analysis of three cases highlights the diagnostic challenges posed by gliomatosis cerebri.
- MRI demonstrates characteristic patterns of diffuse infiltration.
Implications:
- Establishing an in vivo diagnosis of gliomatosis cerebri requires a combination of MRI and brain biopsy.
- Accurate diagnosis is essential for appropriate patient management and treatment strategies.
