Tumor (Progressive)
Clinical presentation
Tumors occupying supratentorial regions, and basal ganglia (Meningiomas > Gliomas > other types of tumors). Rarely, vascular space-occupying lesions may be present.
Diagnosis
MRI/CT to detect the site and the type of lesion, and its associated findings (mass effects and edema).
Patho-mechanism
Compression and shearing of nigrostriatal pathways due to mass effects.
Associated features
Parkinsonian features with resting tremor. Rare. Occurs in adults. Cerebral aneurysms and hematomas present in an acute manner.
