title: [Sonography in cystoid cervical space occupying lesions].
abstract: A retrospective analysis of fluid-filled cervical space-occupying lesions is performed. The high echogenicity of some cervical cysts is due to the difference of the acoustic impedance of water and agglomerated cholesterol crystals. A sonomorphological differential diagnosis of cystoid cervical tumors and fluid accumulations is performed. Uncommon criteria of cysts and new techniques for the differentiation of cystoid cervical lesions are discussed. The clinical role of sonography in the diagnosis of cervical cysts and cystoid lesions is evaluated on the basis of 180 histologically proved cases.
