Long-Term Consequences of Misdiagnosis of Parathyroid Adenomas in Pediatric Patients
Abstract
Primary hyperparathyroidism (PHPT) is rare in children but exhibits a more dynamic course than in adults, often leading to multiorgan complications if diagnosis is delayed. This article aims to highlight diagnostic challenges of parathyroid adenomas in children and discuss associated complications from delayed diagnosis. Three boys, aged 15.5, 10, and 16 years, were retrospectively analyzed for hypercalcemia. The diagnosis was based on biochemical and hormonal tests, as well as imaging studies (ultrasound, scintigraphy, and densitometry). The mean diagnosis delay was 20 months (9-35). All boys experienced appetite loss and bone symptoms. Patient 1 was initially misdiagnosed with slipped capital femoral epiphysis (SCFE) and underwent orthopedic surgery without recognition of severe hypercalcemia. Patient 2 was misdiagnosed with vasopressin deficiency following a tibia fracture. Patient 3's symptoms were attributed to stress. All patients had parathyroid adenomas, but Patients 2 and 3 had an ectopic thymus location. Following adenoma excision, Patients 2 and 3 developed hypocalcemia, the lasting consequences of which included nephrocalcinosis and low bone mass; Patient 3 also developed hypertension and depression. Conclusions: (1) any child presenting symptoms such as loss of appetite, abdominal pain, weight loss, depression, or bone abnormalities must urgently have serum calcium levels assessed to exclude PHPT. (2) Delayed diagnosis of PHPT in children is dangerous, as it…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
