Transorbital penetrating injuries are unusual but may cause severe brain damage if cranium is entered. These kinds of injuries are dangerous as the walls of orbit are very thin, hence easily broken by the otherwise innocent objects. Because of the very critical anatomical area involved, these injuries pose a serious challenge to the physicians who first receive them as well as the treating team. These may present as trivial trauma or may be occult and are often associated with serious complications and delayed sequel. Prompt evaluation by utilizing best diagnostic modality available and timely interference to remove them are the key aspects to avoid damage to vital organs surrounding the injury and to minimize the late complications. We report a case of transorbital assault with a 13 centimeter long knife which got broken from the handle and the blade was retained. The interesting aspect is that there was no neurological deficit on presentation or after removal.

SUMMARY After the spine, the knee joint is the most commonly affected joint in skeletal tuberculosis. Baker's cyst is a rather rare complication of knee joint tuberculosis. The plain radiographic appearance of the tuberculous knee joint has been amply described. We present the magnetic resonance appearance of a tuberculous knee joint associated with a ruptured popliteal cyst.

Oral cholecystography was performed on ultrasonically proven cases of cholelithiasis. The conventional screen/film system and computed radiography (CR) using the imaging plate were used under practically identical conditions. The diagnostic accuracy of the two techniques was assessed objectively, and the image quality was assessed subjectively. The CR image proved to be better than the conventional screen/film image, even with the low-dose exposure. This paper describes our experience in the area of the biliary tract system with CR - a digital radiographic system using photostimulable phosphor.
