Summary:

Description
  • Radiopaedia case ID: 86690
  • Image ID: 54363059
  • Image stack position: 1/75
  • Plane projection: Axial
  • Aux modality: T1 C+
  • Study findings: Right cerebellar mass extending into the left side with likely involvement of the vermis. Central high T2 signal hyperintensity and T2/FLAIR heterogeneity is demonstrated. Peripheral enhancement with corresponding abnormally low ADC value. Mass effect on adjacent structures with effacement of the fourth ventricle. Enlarged lateral ventricles and third ventricle with surrounding T2/FLAIR hyperintensity within the periventricular white matter is consistent with hydocephalus and associated transependymal edema. Conclusion: Right cerebellar mass with obstructive hydrocephalus. Differentials include metastatic disease and high grade glioma.
  • Modality: MRI
  • System: Central Nervous System
  • Findings: Moderate dilatation of both lateral ventricles with extensive low attenuation of the surrounding white matter consistent with transependymal edema. Marked heterogeneity of the cerebellar hemispheres more prominent on the right side and distortion of the fourth ventricle. Early tonsillar herniation no more than 5mm in depth. No intracranial hemorrhage of infarction. Conclusion: Poorly defined right cerebellar lesion likely metastatic disease causing severe mass effect and obstructive hydrocephalus.
