A 35-year-old woman presented with lower abdominal pain and amenorrhoea. CT showed a thick walled lobulated mass with Ascaris adjacent to caecum along with the presence of a left ovarian mass. The peroperative findings were a tubular mass with central tunneling containing an Ascaris lumbricoides. Left ovary showed a haemorrhagic cyst. Biopsy of the mass showed acute on chronic granulomatous inflammation and the worm was found to be female. This was a rare case of Ascaris lumbricoides presenting as a pseudotumorous mass.
