Molar tooth sign (abdomen)
Abdominal molar tooth sign refers to the appearance of contrast media spilled out of the urinary bladder on CT cystography after extraperitoneal bladder rupture.
Contrast flows out of the ruptured bladder, occupying preperitoneal cavum Retzii and surrounds the bladder in the shape of a molar tooth.1
