Ovarian serous cystadenoma

Case contributed by Dr David Cuete

Presentation

Palpable abdominal mass

Patient Data

Age: 40 years
Gender: Female

CT abdomen and pelvis

CT

CT of the  patient shows a multi-loculated cystic mass adjacent to the bladder,  with a smooth
contour, and septa. Small calcifications.  The lession shows homogeneous CT attenuation and no endocystic or exocystic vegetation.

Case Discussion

On the basis of this CT the distinction between a serous and mucinous ovarian tumor cannot be made but some features can aid in differentiating mucinous from serous tumors: like  a unilocular or multilocular cystic mass with homogeneous CT attenuation , with a thin regular wall or septum, and usually no endocystic or exocystic vegetation is considered to be a serous cystadenoma.
