Methods and materials
A total of 16 women aged between 24 and 44 years were included in the study.
These patients had a total of 16 AWE lesions. There was no history of operation in four patients.
There was a history of diagnostic laparoscopy in two patients.
All other patients had a history of prior gynecological operation (cesarean sections in 10 patients).
In 11 patients,
ultrasonography (US) examination prior to MRI revealed an anterior abdominal wall mass that was suspicious of AWE.
MR imaging of the pelvis was performed at 1.5 T.
The size,
location and MRI appearances of the lesions were recorded on T1W,
T2W and post-contrast fat suppression T1W images.
Intravenous contrast medium was used.MRI examinations were performed during the menstrual period if possible.
In all patients,
additional DWI was performed.
ADC values were calculated using b values of 50,
400,
and 800 s/mm2.
A region of interest (ROI) of at least 30 mm2 was placed on the ADC map at the location of AWE.
A region of interest (ROI) was placed on the ADC map at the location of AWE (correlation with T2-weighted images).
In addition,
ADC values of adjacent rectus abdominis at lesion level were measured in all patients.
MR images of all patients were also evaluated for deep infiltration endometriosis,
endometrioma,
and adenomyosis.
In all other patients except three cases,
the diagnosis of AWE was confirmed histopathologically.
All images were reviewed in consensus by experienced radiologists (M.A,
B.Y) in woman imaging.
