Ruptured endometrial cysts as a rare cause of acute pelvic pain: can we differentiate them from ruptured corpus luteal cysts on CT scan?

abstract：:A simple technique using stereotactic needle placement for retrobulbar anesthesia is reported. The method utilizes a CT-guided stereotactic device that permits precise intraconal injection of local anesthetics; in addition, the risk of injury to muscles, vessels, eyeglobe, or optic nerve is substantially reduced. ...
