Ice-cream cone sign
The ice cream cone sign may refer to:
- the appearance of the malleus head and the incus body on axial CT scan: failure of this normal configuration suggests incudomalleolar dysarticulation. Ball of the ice cream is formed by the head of malleus and cone is formed by the body of the incus. Space between ice cream cone and scutum is called as "Prussak's space"
- a medium sized (1.5 to 3 cm) acoustic schwannoma: typical appearance, with the intracanalicular component representing "the cone" and the cerebellopontine angle (CPA) component representing the "ice cream"
