Role of transabdominal sonography in diagnostic evaluation of pelvic masses.
J Postgrad Med Inst Jan ;20(4):335-9.

Objectives: To find out the accuracy of ultrasound in differentiating different pelvic masses Material and Methods: This descriptive study was conducted in the department of Obstetrics and Gynaecology unit A, Khyber Teaching Hospital Peshawar during the years 2001-2002. Total 69 cases with the clinical suspicion of pelvic masses were included in the study. All the patients were admitted and underwent detailed clinical examination and then Transabdominal Ultrasonography (US). Final diagnosis was confirmed at operation findings. Results: Out of 18 (26.1%) cases of fibroid uterus on US, 14 (77.8%) cases were confirmed on laprotomy. US showed 14 cases of simple ovarian tumours and 11 cases of malignant ovarian tumours while postoperatively 13 and 12 cases had simple and malignant ovarian tumours respectively. Out of 10 cases of chronic ectopic pregnancy on US, 7 cases were confirmed on laprotomy. Dermoid cysts, haemtocolpos and haematometra were correctly diagnosed in all case. Diagnosis was misleading in 8/69 (11.6%) cases. Out of 4 cases misdiagnosed as fibroid on US, 3 cases had endometriotic cysts and one case had fibroma ovary. Three patients labeled as chronic ectopic pregnancy on US had pelvic abscess, right broad ligament hemorrhagic cyst and right broad ligament fibroid (one case each). One case of malignant ovarian tumour was misdiagnosed as simple ovarian tumour on US. Conclusion: Ultrasonography can be helpful in the diagnosis of various pelvic masses. It can help the surgeon to plan the technique of surgery and anticipate intraoperative complications.
