Calcific tendinitis in the proximal thigh

Calcific tendinitis of the proximal thigh is a benign entity that may cause significant pain. It must be distinguished from chronic or malignant disorders, such as arthritis, infection, and soft tissue/cortical neoplasms. Although it may be self-limited, some patients will benefit from medical intervention. In such cases, we recommend computed tomography-guided percutaneous steroid injection. Herein we describe the clinical and radiographic features of calcific tendinitis of the proximal thigh in 5 patients.     

Calcific cerebral embolism in systemic calciphylaxis

Calciphylaxis represents a rare complication of end-stage renal disease with hyperparathyroidism. We report the case of a 26-year-old woman with systemic calciphylaxis secondary to chronic renal failure who developed mitral annular calcification and a right middle cerebral artery stroke. The high-density lesion seen on CT scan of the brain probably represents a calcified cerebral embolus originating from the mitral valve.     

Calcific chronic lateral epicondylitis: a histological and ultrastructural study

Fragments of insertion tissue from right arm common extensor muscle have been collected from a 25-year patient with chronic lateral epicondylitis. Specimens, processed for light (LM) and electron (EM) microscopy, evidentiated a variety of degenerative alterations, such as focal hyalinosis, lipoidosis, collagen fiber redistribution, calcifications and vascular changes. Evidence of collagen normal function maintenance and turnover have been also observed in tenocytes.     

Calcific tendinitis of the pectoralis major insertion. A report of two cases

The authors described developmental anomaly of the right kidney associated with hypertension and pyonephrosis in a 37 years old male. The authors reported the diagnostic problems in this kind of hypertension. After nephrectomy had been performed the elevated blood pressure returned to normal values without any additional pharmacological treatment.     

Calcific tendinitis in the posterior proximal thigh as a self-limited condition: pathogenic role of inflammatory responses

OBJECTIVE: Calcific tendinitis occurs rarely in the posterior proximal thigh. We investigated whether it is self-limited and how the natural course of the disease progresses. METHODS: We treated 6 patients with no surgical intervention, and analyzed laboratory and radiological findings in the followup period of more than one year (average followup, 2.5 yrs). RESULTS: Although tendinitis was severe, rapid relief was observed within 2 weeks (average 5 days). Radiological features including extraskeletal calcifications did not change within 2 weeks, and then improved by 6 weeks. Four of 6 cases showed abnormal laboratory variables. All elevated white blood cell counts and C-reactive protein levels improved within one week with clinical resolution. In comparison with time course of the symptoms, changes in the radiological findings over time appeared not to be parallel with the clinical course, but laboratory progression appeared to correspond well with clinical resolution. CONCLUSION: Inflammatory responses to hydroxyapatite crystals may play a role in the pathogenesis of symptoms of calcific tendinitis in the posterior proximal thigh, most of which are self-limited.
