Ice-cream cone sign

Dr Praveen Jha and Dr Mohammed Wahba et al.

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 icecream is formed by head of malleus and cone is formed by body of incus. Space between icecream cone and scutum is called as "Prussack'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"
