Rice grain calcification

Rice grain calcification is characteristic of infection with Taenia solium (cysticercosis); when the inflammatory response of the host kills the larval cysts (cysticerci), they undergo granulomatous change and become calcified.

Radiographic features

Ovoid flecks of calcification resembling grains of rice in the soft tissues. The calcifications parallel the long axis of the muscle.
