Low back pain is probable the second most common disease entity to upper respiratory infection in developedconuntry. We were missing at least 50% of the pathologic conditions by using conventional diagnostic modalities inlow back pain. They did tell us nothing or little about facet abnormalities, lateral recesses, vertebral canal andsoft tissues surrounding lumbar spines. High resolutional CT has been the biggest turning point in the diagnosisand management of low back pain. CT make a contribution to reducing the morbidity and probable the cost ofevaluating patiens with low baack pain, and to increasing diagnostic accuracy. We observed 100 cases of lumbar CTusing TCT 80A scanner for the evaluation of low back pain during the period from Apr. 1985 to Sept. 1985 atChung-Ang University Hospital. Lumbar CT scan reveals high-positive findings(98%) in low back pain patients.Common low back disorders in CT are disc bulging(53%), herniated nucleus pulposus(32%), degenerative arthritis inposterior facet joints (27%), spinal stensosis(20%) and postoperative spines(15%). Uncommon low back disorders inCT are compression fracture of verebral bodies, spondylolysis or spondylolisthesis, tropism, transitionalvertebra, Scheuerman's disease, limbic fracture, transverse process or articular process fracture, sacroiliacjoint subluxation, conjoined nerve root and meningocele.

The authors present a case of intracranial aneurysm with Takayasu's arteritis. A 10-year-old boy was admitted with complaints of sudden bursting headache and vomiting. Computed tomographic(CT) scan showed subarachnoid hemorrhage and measure blood pressures between in each side did differ significantly. Aortoangiogram showed narrowing of the abdominal aorta and stenosis at their origins of the renal arteries. An angiogram of the right carotid artery revealed a saccular aneurysm located at the proximal portion of the middle cerebral artery. Intracranial aneurysm with Takayasu's arteritis is a rare entity, even more in children.

Duodenal diverticulum is commonly found at 2nd portion of duodenum undergoing duodenal procedure. It is generally asymptomatic and not harmful. But occasionally it causes massive upper gastrointestinal bleeding. Bleeding from duodenal diverticulum is very difficult to diagnose and manage since vision of the lesion by conventional direct endoscope is limited. Recently, emphasis has been placed on aggressive and careful endos- copic diagnosis and hemostasis with hemoclip or local injection. We report a case of massive duodenal diverti- cular bleeding on a senile patient which was treated successfully by endoscopic hemoclip therapy.
