The Etiology of Ring Lesions on Diffusion-Weighted Imaging

“…ANE was reported in three cases in the literature, all with bilateral thalamic lesions while three cases of BCS involving the white matter were described. In the cases of BCS the lesions were multiple in one and single in two cases and enhancement was seen in all three cases albeit minimal in two 9,10 . Our cases 9 and 10 fulfilled McDonald criteria for definite MS and manifested multiple non-enhancing lesions on …”

Diagnostic Role of Target Lesion on Diffusion-Weighted Imaging

“…The neuroimaging features are predominated by symmetrical lesions of the thalami. 3,4 There is undoubtedly a broader spectrum of disease associated with DWI target lesions than reflected in this review. Nevertheless, until a larger case experience provides perspective on the frequency and specificity of this neuroimaging finding, in the context of an immunocompromised host, target lesions on DWI are an early and highly suggestive finding helpful in the timely diagnosis and treatment of cerebral aspergillosis.…”

“…Target lesions on DWI are uncommon and described in association with a limited number of diseases. [1][2][3][4][5][6] The differential diagnostic value of this neuroimaging feature has heretofore not systematically been considered. We present a case of cerebral aspergillosis and review 8 other cases with target lesions in the context of etiology, immune status and lesion number and enhancement.…”

Elderly‐onset acute necrotizing encephalopathy mimicking severe heat stroke: a case report and review of the literature

“…Similar to our case, ANE could not be diagnosed on admission in several previous cases without the characteristic lesions on the initial CT scan. [5][6][7]9,12,13,16,19,21 As diffusion- weighted imaging is superior for detecting tissue damage in the cerebral parenchyma in the hyper-acute phase, it could be more accurate in revealing cytotoxic edema in ANE. 10 A previous study of 41 child cases of ANE found that abnormal findings characteristic of ANE appeared on CT within 12 h after the onset of coma.…”
