Skeletal muscle hydatid cysts presenting as soft tissue masses.

Muscle hydatidosis is rare, accounting only for 3-5% of all cases. We present a case series of 9 patients (8 male, one female, mean age 59.3 years, range 48-75 years) with primary echinococcosis of skeletal muscles.

A prototype digital ionographic imaging system.

A prototype digital ionographic imaging system is described. The process involves direct electrical reading of a latent electrostatic image which has been produced by an ionographic technique. The main design features of the system are outlined and their effect on its imaging performance highlighted.
