title: [Clinical features of parathyroid space-occupying lesions].
abstract: OBJECTIVE
  To investigate the clinical manifestation, diagnosis, treatment of parathyroid occupying lesions.
  
  
  METHODS
  The clinical data of 42 patients with parathyroid occupying lesions were retrospectively analyzed, including the clinical symptoms and signs, laboratory results, pathologic and imaging results and treatment.
  
  
  RESULTS
  The number of males and females were 8 and 34, with females: males ratio being 1:5.25. The median age was 39 years. There were 2 cases of parathyroid cancer, 29 cases of parathyroid adenoma, 11 cases of parathyroid cysts in this study. The symptoms were as follows: 40 cases of neck lump, 34 cases of osteoporosis/osteitis fibrosa cystica, 29 cases of urinary symptom, 7 cases of voice hoarseness, 4 cases of peptic ulcer, 3 cases of dyspnoea and dysphagia, 3 cases of thoracic cavity lump, 2 cases of enhanced amylase activity. Serum calcium ion level and serum parathyroid hormone (PTH) level were examined qualitatively before operation. Ultrasonography, ECT-99mTc-MIBI, CT, MRI were used in diagnosing and locating parathyroid occupying lesions before operation. Twenty nine cases of parathyroid adenoma were treated with operation, 28 patients achieved complete remission, 1 suffered relapse after 23 months postoperative follow up. Eleven cases of parathyroid cysts were treated with operation and the outcome was no recurrence. Two cases of parathyroid cancer survived with out recurrence during follow up for 28 months and 50 months after operation.
  
  
  CONCLUSIONS
  Examination of serum calcium and PTH level together with ultrasonography, ECT-99mTc-MIBI, CT, MRI is helpful to diagnose parathyroid occupying lesions. Surgery should be done as primary treatment. Tumor resection can be performed for parathyroid cysts, intraoperative exploration of bilateral neck is indicated for parathyroid adenoma, and a radical resection should be performed primarily for the parathyroid cancer.
