Case contributed by Dr Ahmed Mahrous Saied

Presentation

Young female patient presenting with pelvic colic

Patient Data

Age: 34
Gender: Female
Modality: MRI

These MRI images reveal the characteristic appearance of the polycystic ovaries:

  1. Both ovaries are enlarged in size.
  2. Both ovaries contain an abnormally large number of follicles (>10-12 each).
  3. All follicles show more-or-less similar size with no dominant follicles detected (size <10 mm).
  4. The follicles display abnormal distribution being arranged peripherally (showing the characteristic "string of pearls" appearance).

Case Discussion

When diagnosing polycystic ovaries, one can apply the ten rule:

  1. Volume of each ovary (>10 cm3).
  2. Each ovary contains (>10 follicles).
  3. Each follicle diameter (<10 mm).
