MRI manifestations of cerebrum in idiopathic hypoparathyroidism / 中国医学影像技术

ABSTRACT

Objective To assess the MRI features of cerebrum in idiopathic hypoparathyroidism (IHP). Methods MR images of 27 IHP patients were analyzed retrospectively emphasized on the location, appearance and signal intensity of the lesions. Results MRI showed symmetric abnormal signals in basal ganglia in 27 patients, in thalami and dentate nucleus in 21 patients, and in corona radiata-centrum ovale in 9 patients. All the lesions were hyperintensity on T1WI. Local hypointensity in basal ganglia was found in 4 patients, while hyperintensity or slight hyperintensity on both T2WI and T2-FLAIR were found in 26 patients, and slight hyperintensity with hypointensity on both T2WI and T2-FLAIR in 1 patient. Conclusion MRI of IHP has some features. Symmetric high signals on both T1WI and T2WI in basal ganglia, thalami and dentate nucleus have important diagnostic value for IHP.
