Imaging Findings in Two Cases of Fluoroquinolone-Induced Achilles Tendinopathy

Multiple spontaneous tendon ruptures from enthesis failure in primary hyperparathyroidism: a case report and review of imaging findings

Cases of spontaneous tendon ruptures have been previously reported in the literature. Although both renal failure and hyperparathyroidism have been implicated as separate aetiologies, their frequent co-existence has confounded analysis. We report a case of a young man with primary hyperparathyroidism presenting with multiple acute spontaneous tendon ruptures. This case affords an opportunity to evaluate the imaging features of acute spontaneous tendon ruptures in the context of primary hyperparathyroidism, and in conjunction with a review of previous literature reports, an imaging-based hypothesis on the pathophysiology and aetiology of spontaneous tendon ruptures is proposed.
