Ectopic parathyroid adenoma

Case contributed by Dr Ian Bickle

Presentation

Middle aged women with recurrent renal stone disease

Patient Data

Age: 45
Gender: Female
X-ray

Bilateral renal stones.

X-ray

A chest radiograph was performed prior to percutaneous nephrolithotomy (PCNL). 

Right sided mediastinal mass, which demonstrates the hilum overlay sign.

Nuclear medicine

A MIBI scan was undertaken to assess for a parathyroid adenoma. 

Avid tracer uptake in the mediastinal mass visualised on plain chest radiograph, confirms it represents an ectopic parathyroid adenoma.

Case Discussion

In a small number of cases, recurrent renal stone diseases (nephrolithiasis) is due to an underlying metabolic condition. This includes primary hyperparathyroidism due to a parathyroid adenoma. Rarely these occur in an ectopic location, typically the mediastinum, rather than in the neck.
