Pain Characteristics in Ovarian Torsion During Palpation
Patients with ovarian torsion typically experience severe, sharp pain with tenderness during palpation of the affected adnexal region, which is a key diagnostic finding that should prompt immediate surgical evaluation. 1
Clinical Presentation During Examination
- Palpation of the abdomen in ovarian torsion cases reveals severe unilateral lower abdominal tenderness, often with a palpable laterouterine pelvic mass 1, 2
- The pain is typically constant but may fluctuate in intensity, rarely completely resolving without intervention 1
- During bimanual examination, patients often demonstrate exquisite tenderness in the adnexal region of the affected side 1
- The pain may be accompanied by nausea and vomiting, which are common associated symptoms 2, 3
Diagnostic Challenges During Physical Examination
- Ovarian torsion can be mistaken for other conditions during palpation, such as appendicitis, pyelonephritis, or renal colic due to similar pain characteristics 4
- Not every patient will have a palpable mass on examination, making the diagnosis more challenging 4
- The American College of Radiology notes that transvaginal ultrasound combined with transabdominal views provides the most comprehensive assessment when physical examination findings suggest torsion 1
Key Physical Examination Findings
- Acute onset of unilateral lower abdominal pain with tenderness to palpation is the hallmark physical finding 3
- Palpation may reveal an enlarged, tender ovary or adnexal mass 1, 5
- The severity of pain during palpation is often disproportionate to the physical examination findings, which should raise clinical suspicion for torsion 4
- Pain may be elicited with gentle movement of the cervix during bimanual examination 1
Important Clinical Considerations
- Normal physical examination findings do not rule out ovarian torsion, as the condition can be intermittent 4
- Patients may have symptoms for several hours or days, and thus, ovarian torsion may still be present even with a longer duration of symptoms 4
- In postmenopausal women, ovarian torsion is often associated with an underlying mass and may present with more subtle findings during palpation 6
- The American College of Radiology emphasizes that early recognition of characteristic pain during examination is crucial for timely intervention to preserve ovarian function 1
Imaging Correlation with Physical Findings
- When physical examination suggests ovarian torsion, ultrasound is the first-line imaging modality with findings including unilaterally enlarged ovary, peripheral follicles, and abnormal or absent venous flow 1
- The "whirlpool sign" on ultrasound represents the twisted vascular pedicle and supporting ligaments, with a sensitivity of 90% in patients with confirmed adnexal torsion 1
- MRI has 80-85% sensitivity for ovarian torsion and can be used when ultrasound findings are inconclusive but clinical suspicion based on physical examination remains high 1, 7
Common Pitfalls in Physical Examination
- Relying solely on physical examination findings without appropriate imaging can lead to missed or delayed diagnosis 4
- Assuming ovarian torsion only occurs in reproductive-aged women; it can affect females of all ages including postmenopausal women 6
- Waiting for all classic symptoms to appear before considering the diagnosis; not all patients will present with the complete clinical picture 4
- Delaying surgical consultation when physical examination findings are concerning despite inconclusive imaging 4
