USG can help in defining morphologic characteristics, but cannot differentiate hydrosalpinx paraovarian
and tubal cysts.

Cysts related to the Mullerian system usually occur in paraovarian
(1) or paratubal regions (2).
A similar condition of endometriosis and paraovarian
cyst in a rhesus macaque was reported by Green et al.
This is true of most dermoid cysts, endometriomas, corpus luteum cysts, hydrosalpinges and peritoneal pseudocysts, and of many paraovarian
cysts and benign solid ovarian tumours, for example, fibromas, fibrothecomas, thecofibromas, and thecomas.

It is a common tumor of male paratesticular tissues (epididymis, tunica or spermatic cord) and has also been described in females (uterus, fallopian tube, ovary and paraovarian
Examples of such lesions that may be accurately diagnosed by MRI include peritoneal inclusion cysts (Figure 7), pedunculated fibroid cysts, paraovarian
cysts, paratubal cysts, or lymphadenopathy.
3) Non-neoplastic lesions, tumour-like conditions, paraovarian
lesions and metastatic tumours were excluded from the study.
