This study evaluated the diagnostic value of preoperative pelvic MRI in 13 patients with clinically suspected endometriosis by comparing MRI findings with laparoscopic visualization and histopathologic confirmation. MRI identified endometriosis in 9/13 patients, and across lesions it showed 19 endometriotic locations, with 14 (74%) confirmed histopathologically after laparoscopy; however, 5/19 MRI-detected lesions were not seen during laparoscopy. Conversely, laparoscopy/histopathology identified 27 endometriotic lesions in total, with 13 (48%) not detected on preoperative MRI, and in 2 patients lesions were detectable only by laparoscopy. Limitations include the small sample size and the fact that performance is judged relative to laparoscopy and histopathology. This paper is centrally about endometriosis — it assesses pelvic MRI’s ability to preoperatively diagnose and document the extent of endometriosis relative to laparoscopy.

Abstract

PURPOSE: To determine the value of magnetic resonance imaging (MRI) of the pelvis in the preoperative diagnosis of endometriosis. MATERIALS AND METHODS: Over a period of 8 months, preoperative MRI of the pelvis were obtained in 13 patients with suspected endometriosis (mean patient age 34.6 years; range 25 - 47 years). RESULTS: In 9 of 13 patients (69 %), the diagnosis of endometriosis was made by MRI and confirmed by laparoscopy in 8 cases. In 2 of 13 patients, endometriotic lesions were detectable by laparoscopy only. In the remaining 2 patients, no endometriosis was visible on MRI or by laparoscopy. MRI was able to visualize a total of 19 endometriotic lesions, with 14 (74 %) confirmed by histopathologic examination following laparoscopy. Five of these 19 lesions (26 %) visible on MRI were not seen by laparoscopy. Using laparoscopy and subsequent histopathologic examination, 27 endometriotic lesions were diagnosed, with 13 (48 %) not seen on the preoperative MRI. CONCLUSION: MRI and laparoscopy are complementary diagnostic tools that will best document the full extent of endometriosis when combined. MRI can visualize additional lesions inaccessible to laparoscopy. Thus, MRI of the pelvis should used preoperatively for surgical treatment planning.

Baumgarten, Essen, für die unterstützende Zusammenarbeit.Publication History Publication Date: 26 August 2004 (online) Zusammenfassung Ziel: Bestimmung der diagnostischen Wertigkeit der Magnetresonanztomographie (MRT) des Beckens in der präoperativen Diagnostik der Endometriose. Material und Methoden: Innerhalb von 8 Monaten führten wir bei 13 Patientinnen, bei denen klinisch der Verdacht auf eine Endometriose bestand (Alter: 25 - 47 Jahre, mittleres Patientenalter: 34,6 Jahre), eine präoperative MRT des Beckens durch. Ergebnisse: Bei 9 von 13 Patientinnen konnte in der MRT die Diagnose der Endometriose gestellt werden. Bei 8 Patientinnen wurde die Diagnose laparoskopisch bestätigt. Bei 2 von 13 Patientinnen konnten nur in der Laparaskopie Endometrioseherde festgestellt werden. Insgesamt konnten 19 Lokalisationen der Endometriose mittels MRT gesehen werden, von denen sich 14 (74 %) histopathologisch bei der Laparaskopie bestätigten. 5 (26 %) von 19 Lokalisationen in der MRT konnten in der Laparaskopie nicht gesehen werden. In der Laparaskopie konnten insgesamt 27 Endometrioselokalisationen histopathologisch diagnostiziert werden, wovon sich 13 (48 %) in der präoperativen MRT nicht darstellten. Schlussfolgerung: MRT und Laparaskopie stellen einander komplementäre diagnostische Verfahren dar, die zusammen das genauere Ausmaß der Endometriose dokumentieren. Die MRT zeigt auch Läsionen, die in der Laparaskopie nicht einsehbar sind. Die MRT des Beckens sollte deshalb präoperativ zur Operationsplanung eingesetzt werden.
