Numerous cervical nabothian cysts.BLADDER: No significant abnormality noted.LYMPH NODES: No significant abnormality noted.BOWEL, MESENTERY: Small amount of free pelvic fluid, most likely physiologic in etiology.BONES, SOFT TISSUES: Degenerative disc disease at L5/S1.OTHER: No significant abnormality noted.
