Familial osteopoikilosis.

Osteopoikilosis (OPK) is a rare, autosomally inherited, benign sclerosing bone dysplasia of unknown etiology. It is usually found incidentally on radiological examination, presenting as multiple, small, well-defined,variably shaped and widely distributed sclerotic areas throughout the skeleton. In this study, we present a case report of a 56-year-old man suffering from low back pain who was radiologically diagnosed with OPK. His daughter was likewise diagnosed with OPK.
