AFP and neoplasm: A firm, 18-cm cystic-solid mass was palpated in the lower abdomen, with no nodules detected in the rectouterine pouch (pouch of Douglas).Contrast-enhanced CT demonstrated a large complex cystic-solid mass (21.1 cm × 9.9 cm × 23.2 cm) encasing bilateral adnexa, radiologically suggestive of malignant mucinous adenocarcinoma of ovarian origin(Figure 1B).The laboratory tumor marker results showed a mildly elevated level of Alpha-fetoprotein (AFP), while the remaining markers were within normal ranges (Table 1).
