topped the list of most common benign ovarian tumours 82(32.8%), benign teratomas 73(29.2%), mucinous cystadenoma 59(23.6%), serous cystadenofibroma 14(5.6%), monodermal tumour 10 (4%), fibrothecoma 5(2%), fibroma 5(2%), and cystadenoma 1(2.5%).

The macrocystic or oligocystic variant of serous cystadenoma
is uncommon and difficult to distinguish from mucinous cystic neoplasm by imaging.
Many authors described a higher frequency of pancreatic intraepithelial neoplasia in patients with pancreatic ductal adenocarcinoma, but also reported that it may be present in patients with the following disorders of the pancreas: mucinous cystic neoplasms, neuroendocrine tumors, chronic pancreatitis, serous cystadenomas
, acinar cell tumors, and pseudopapillary tumors .
is also a benign tumour of the ovary, which is responsible for about 30% of all epithelial ovarian neoplasms.

Mucinous cystadenomas tend to be much larger than serous cystadenomas
at presentation (14).
Agah, "Papillary serous cystadenoma
of ovary: a huge ovarian cyst complicating the pregnancy".
The most common benign adnexal mass observed in our study was mucinous cystadenoma, closely followed by mature cystic teratoma and serous cystadenoma
. This observation is similar to previous studies.
The commonest benign lesion was hemorrhagic luteal cyst in 50(20.2%) cases followed by follicular cyst and serous cystadenoma
in 49(19.8%) each.
In case of connection, a diagnosis of IPMN could be suggested , whereas when connection is not identified, alternative diagnoses should include serous cystadenoma
or mucinous cystadenoma.
Among benign, most common diagnoses were follicular / luteal cysts (34.8%) followed by serous cystadenoma
(24.6%) and serous cysts (15.4%).
