Describe the role of transvaginal sonography in the evaluation of presacral lesions.
Identify the sonographic characteristics of presacral epidermoid cysts and related differential diagnoses.
Explain the diagnostic approach and management considerations for presacral masses based on imaging and pathology findings.
According to the article, where is the presacral space anatomically located? A. Between the rectal wall and the sacrum B. Between the bladder and uterus C. Between the liver and diaphragm D. Between the kidneys and adrenal glands
According to the article, which imaging modality is most commonly used to evaluate presacral lesions? A. Radiography B. Magnetic resonance imaging (MRI) C. Sonography D. Fluoroscopy
Which sonographic feature was identified in the presacral lesion in this case? A. Hypervascular solid mass B. Anechoic lesion with shadowing C. Avascular complex lesion with internal echogenic foci and posterior enhancement D. Calcified lesion with acoustic shadowing
What was a primary reason sonography was performed prior to biopsy in this case? A. To replace computed tomography (CT) imaging B. To determine patient eligibility for surgery C. To measure hormone levels within the lesion D. To assess benign versus malignant features and evaluate risk of tumor seeding
What histologic contents are commonly found within epidermoid cysts? A. Keratin, water, cholesterol, and desquamated debris B. Fat and muscle tissue C. Blood and fibrin D. Calcium and bone fragments
What was the final pathology diagnosis of the lesion in this case? A. Sacrococcygeal teratoma B. Tailgut cyst C. Chordoma D. Epithelial squamous cyst
Which management approach was recommended for this patient following biopsy results? A. Immediate surgical excision B. Chemotherapy C. Radiation therapy D. Conservative management with physical therapy and imaging surveillance
