pain, with –ve PDT. The clinical examination was difficult and
limited.
Ultrasound findings
The transabdominal examination was of limited value, but gave
the impression of reasonably sized cystic mass to the left of
midline (Fig. 3a). A transvaginal scan was performed for further
evaluation. The transvaginal approach facilitated demonstration
of a normal uterus, endometrium and right ovary, and allowed
improved visualization of a thin-walled cyst containing internal
septations arising from the left ovary (Fig. 3b,c).
Diagnosis
Persistent corpus luteum.
