FIG 5. Case 11: Nine-month-old girl with left parotid mass and right hemiplegia.
A, Axial contrast-enhanced CT scan shows focal low density (arrow) within left parotid gland with thickening of adjacent subcutaneous fat and skin.
B, Axial T2-weighted (3200/78/1) fast spin-echo MR image demonstrates high signal intensity involving left corpus striatum (arrows).
C, Axial apparent diffusion coefficient map from line-scan diffusion image (1520/62.5/1; b maximum = 750 s/mm2) shows low signal intensity (arrow) indicating decreased diffusion associated with acute or subacute infarction. Although immunocompetent children with NTM adenitis typically lack systemic symptoms, occurrence of cerebral infarction, possibly owing to vasculitis, in this patient suggests that occasionally the disease process may be more generalized.
