Unusual clinical presentation of a giant parathyroid adenoma: A case report from Morocco highlighting the rare entity and atypical symptoms

Abstract

Primary hyperparathyroidism (PHPT), an endocrine disorder most commonly caused by parathyroid adenoma (PTA), manifests with a diverse array of symptoms, reflecting the multisystem impact of parathyroid hormone: nephrolithiasis, peptic ulcer disease, psychiatric disorders, muscle weakness, constipation, polyuria, pancreatitis, myalgia, and arthralgia. Rarely do these PTA attain a significant size. PHPT is usually diagnosed through biochemical tests, and radiological imaging characterizes the adenoma. Serum 25-hydroxyvitamin D levels are useful in explaining the large adenoma size. Here, we report a rare case of a 60-year-old female from Morocco who presented with marked dyspnea due to a giant PTA.
