A few patients with primary hyperparathyroidism (PHPT) have a chance of spontaneous remission by either infarction of or hemorrhage into or around the parathyroid adenoma. In most cases, biochemical derangements associated with PHPT are permanently improved after spontaneous remission. Here we report a case with a recurrence of PHPT 4 months after spontaneous remission with acute intracapsular hemorrhage of parathyroid adenoma. In the literature, only two cases have been reported to have experienced a recurrence of clinical features of PHPT after infarction but not hemorrhage of parathyroid adenomas. Thus, the spontaneous remission of biological derangements in PHPT upon hemorrhage or infarction of parathyroid adenoma could be temporary. One should carefully observe such patients thereafter.
