Clinical question : 39-year-old female with history of left basal ganglia mass/calcification. Three evaluate for progression. Signs and symptoms: seizure Nonenhanced head CT:Large area of speckled calcification in the left basal ganglia with extension into the thalamus on the left is again identified. There is no evidence of any associated edema or mass effect with this finding. There is also no evidence of any interval change in the extent or size of this lesion. A small calcification is also noted in the right cerebral peduncle similar to prior exam. The exact etiology of this finding is not clear. Finding could represent dystrophic calcification. Possibility of a hemangioma cannot be ruled out. There is linear and punctate appearance of this lesion which may indicate vascular calcification. Correlate with history since this appearance may be result of prior embolization. The common further follow with an MRI examination.This examination is otherwise unremarkable and stable since prior study.
Stable examination since prior study and in particular no evidence of change in the size or distribution of the left basal ganglia -- thalamic calcification. Please see above comments.
