Figure 1From: Parathyroid adenoma apoplexy as a temporary solution of primary hyperparathyroidism: a case report Left inferior parathyroid adenoma. Axial MR imaging scans (07/1998) weighted in T1 (A) and T2 (B) show a spontaneous hyperintense and well defined round lesion in both T1- and T2-weighted in the left-inferior parathyroid adenoma region (arrow). There is a hypointense lesion with a halo in the T2-weighted image which can represent degradation products of hemoglobin (arrowheads).Back to article page
