The median, paramedian, lateral and fundal localizations of the endometriotic lesions within the myometrium of the uterine corpus

Localization	n	%
Fundal	69	49.6
Median	130	93.5
Paramedian	96	69.1
Lateral	23	16.5
Cornual	34	24.5
Cornual cysts (total)	22	15.8
Cornual cysts (accumul.)	11	8.7
Other cysts	38	27.3

As indicated by the localization of the largest diameter of the JZ, the majority of the individual lesions originated in the mid-sagittal region of the anterior and/or posterior wall of the uterus. Also, the fundal and paramedian regions were major primary localizations. Adenomyotic lesions did not primarily develop at the lateral uterine wall or in the cornual region. Adenomyosis at these localizations constituted lateral or cornual extensions of large adenomyotic lesions that primarily originated within the anterior or posterior wall. Cystic structures were a frequent finding. Cysts that accumulated in one or both cornua, however, constituted a distinct entity. The findings exceed 100 % because individual adenomyotic lesions displayed more than only one of these criteria
