Sonographic appearance of adnexal torsion, correlation with other imaging modalities, and clinical history

摘要

This pictorial essay illustrates the varied imaging appearances of adnexal torsion and its diagnostic pitfalls. This is a difficult diagnosis with many false positives and false negatives. Diagnosis is mostly based on clinical history and ultrasound examination, with computed tomography and/or magnetic resonance used to support the diagnosis and to exclude other pathologies.
