Skeletal scintigraphy in coeliac disease. A patient with undiagnosed, long-standing coeliac disease had multiple hot spots on skeletal scintigraphy, similar to those observed in malignant disease metastatic to the skeleton. A gluten-free diet corrected the pathological laboratory values, and a repeat skeletal scintigram 15 months after the first one was normal. It is important to identify the secondary hyperparathyroidism of coeliac disease as a cause of multiple hot spots in skeletal scintigraphy--the finding resembles malignancy, but is due to a benign, curable condition.
