Insufficient Information to Determine Diagnosis
Without access to the actual CT findings and clinical presentation described in your case, I cannot provide a specific diagnosis. The evidence provided consists entirely of imaging guidelines and recommendations for various clinical scenarios, but contains no information about your patient's actual CT results, symptoms, laboratory values, or clinical context.
What Information Is Required for Diagnosis
To determine the most probable diagnosis based on thoracic/abdominal/pelvic CT findings, I would need:
- Specific CT findings: What abnormalities were identified on the scan? (masses, fluid collections, organ enlargement, inflammatory changes, vascular abnormalities, etc.)
- Clinical presentation: What symptoms brought the patient to medical attention? (pain location/character, fever, bleeding, etc.)
- Laboratory data: Relevant values such as white blood cell count, inflammatory markers, β-hCG status, liver function tests
- Patient demographics: Age, sex, pregnancy status, relevant medical history
- Timing and acuity: Acute versus chronic presentation
Common Diagnostic Scenarios Based on CT Abdomen/Pelvis
The guidelines provided address several clinical contexts where CT abdomen/pelvis plays a diagnostic role:
Infectious/Inflammatory Conditions
- Tubo-ovarian abscess appears as a complex cystic mass with thick enhancing walls, with the right ovarian vein entering the abscess having 100% specificity and 94% sensitivity for TOA versus peri-appendiceal abscess 1
- Appendicitis demonstrates 90% sensitivity and 95% specificity on CT in mixed populations 1
- Pyelonephritis/pyonephrosis with renal calculi are commonly identified in urosepsis workup 1
Gynecologic Pathology
- Adnexal torsion shows asymmetrically enlarged ovary with twisted pedicle, abnormal enhancement, and deviation of uterus to the twisted side, with CT sensitivity of 74-95% and specificity of 80-90% 1, 2
- Pelvic inflammatory disease demonstrates pelvic fluid, loss of fat planes, thickened fallopian tubes with enhancement, and ovarian enlargement 3
Vascular Abnormalities
- Ischemic liver injury from hypoperfusion shows hypoenhancement of liver parenchyma 1
- Atherosclerosis and thrombus are among the most commonly missed findings on abdominopelvic CT 4
Next Steps
Please provide the actual CT report findings and relevant clinical information so I can formulate a specific diagnosis based on the imaging results and clinical context.
