Metastatic microcalcification in the lungs and stomach due to hyperparathyroidism: A case report.

We present a case of a 34-year-old man who was admitted to our hospital with a six-month history of nausea and vomiting that had worsened over the past two weeks. Diagnosis of primary hyperparathyroidism (PHPT) due to a single parathyroid adenoma was confirmed by laboratory results and imaging but following pharmacological therapy the patient developed a dry cough. Single-photon emission tomography/computed tomography (SPECT/CT) with technetium-99m-diphosphonate (99mTc-MDP) was used to assist in the diagnosis and results showed diffuse metastatic microcalcification in the lungs and stomach. The patient underwent right parathyroidectomy and 99mTc-MDP SPECT/CT scan six months later showed a significantly reduced radioactive distribution in the lungs and none in the stomach. Diffuse metastatic microcalcification in the lungs and stomach due to PHTP is rare and can easily be misdiagnosed.
