A sixteen-year-old @entity1 presented to our outpatient clinic with difficulty in walking due to swelling of both ankles. Ultrasonography revealed intratendinous calcific nodules in both Achilles tendons. Serum biochemistry showed @entity2741 and @entity5886 . Serum parathormone level was high (512 pg/mL). Parathyroid scanning revealed a suspected @entity3243 . The @entity1 underwent parathyroidectomy and the diagnosis of @entity3243 was confirmed by histopathology. Serum levels of @entity461 , @entity4613 , and @entity460 returned to normal, and the tenderness over the Achilles tendon and the flow pattern on Doppler examination disappeared as well.
