Cystic Parathyroid Lesions

Diagnostic and therapeutic review of cystic parathyroid lesions.

BACKGROUND Parathyroid cysts (PC) are uncommon entities in routine clinical practice. The vast majority are nonfunctioning and are commonly present as asymptomatic nodular cervical lesions. PC should be considered in the differential diagnosis of an asymptomatic neck mass. Large PC can manifest with compressive symptoms of the surrounding tissues. OBJECTIVE The aim of this study is to describ...

Imaging of parathyroid lesions with radionuclides - Is it worth doing?

Parathyroid adenomas, or hyperplasia may be present in patients with hypercalcemia. Treatment Is by surgical excision, but about 10% of the lesions may be In ectopic locations. Pre-operative localization of the lesions with non-lvasive imaging, using radionuclides, ultrasound, CT, or MR], may simplify surgery, and reduce patient morbidity. However, the reports of the accuracy of the curre...

Differentiating Pancreatic Cystic Lesions

Pancreatic cystic lesions (PCLs) may represent malignant or premalignant neoplasms and require diagnostic evaluation. Patient’s demographics and clinical presentation should be considered when diagnosing PCLs. Radiologically, location, ductal relation, external contour, wall, and septal enhancement give important clues for each type of lesion. Imaging features that suggest a high malignancy ris...

Physiologic Cystic Ovarian Lesions

Owing to multiplanar imaging capabilities and excellent tissue characterization, MRI can facilitate definitive diagnosis of benign conditions of the female pelvis. The purpose of this chapter is to review the spectrum of common benign conditions of the female pelvis and to illustrate the MRI features of these conditions, with an emphasis on the key imaging characteristics to suggest accurate di...
