The solitary (youthful) bone cyst is observed mainly in male people (the ratio of boys and girls 3: 1), most often aged 10-15 years. Adults are rarely detected, mainly as not revealed in the past.
Manifestations of solitary cysts
Long tubular bones are almost always affected, usually shoulder or hips.
