With an average incidence rate of 0.07-1.15%, foetal adenomyomatosis is a rare discovery during a third- trimester ultrasound. We describe a case of foetal adenomyomatosis that occurred at 37 weeks' gestation and was diagnosed 4 days after delivery. Clinicians must be aware of the implications of this illness and how to treat it effectively. A degenerative and proliferative condition called gall bladder adenomyomatosis is characterised by excessive epithelial proliferation along with muscularis propria hypertrophy. This results in intramural diverticula known as Rokitansky- Aschoff sinuses, which are mucosal outpouchings into or beyond the muscle layer (RAS). These sinuses get clogged with cholesterol crystals, which cause the comet tail artefacts on USG that are indicative of adenomyomatosis and are caused by reverberation artefacts. Because it is benign, there is typically no need for therapy. The condition resolves on its own and ultrasonography follow-up is necessary. Surgery is required when the condition is not resolving or the patient is symptomatic.
