Unilateral Stimulation of the Right Ovary in a 10-Year-Old Girl with Perforated Appendicitis.

Introduction ▼ Transabdominal ultrasound is the imaging modality of choice in the evaluation of girls with pathologic ovarian conditions such as ovarian masses, ovarian torsion or hemorrhagic ovarian cysts. The shape of the ovaries and their structure, size and blood flow can be determined by ultrasound. Before puberty, the ovaries have a volume of about 1 ml and contain small, non-stimulated follicles (I.J. Griffin et al. Acta paediatrica 1995; 84: 536– 543). The presence of unilateral ovarian enlargement in a prepubertal girl may be a sign of torsion or of an ovarian mass and usually warrants further radiological evaluation or laparoscopic exploration (M.F. Brown et al. J Pediatr Surg 1993; 28: Unilateral Stimulation of the Right Ovary in a 10-Year-Old Girl with Perforated Appendicitis
