Differentiation between acute and old fractures in the thoracic and lumbar spine is often difficult. We have evaluated the intraobserver agreement and interobserver variability of interpretations. We have prepared 50 cases from 40 patients with thoracic or lumbar spine fracture for evaluation. At first, two radiologist interpreted each of the 50 cases, Only by using plain roentgenograms. Then, they interpreted the cases again using also spine CT, MRI, bone scintigrams and follow-up roentgenograms. Intraobserver agreement was found to be 78% in Doctor A, and 76% in Doctor B. Interobserver agreement was only 62% at first. It was 88%, when they used CT, MRI, bone scintigrams and follow-up roentgenograms. It was not easy to differentiate the old fractures from acute one only by plain roentgenograms. Differentiation was more difficult, when the patient was female or over 55 years old. Plain roentgenography in hyperextension posture seems to be a simple but useful method for the diagnosis of the acute fracture. MRI was more valuable than CT or bone scintigraphy to differentiate the old fractures from the acute ones.

Injury to a lumbar disc is rare, and is seldom mentioned in the literature describing spinal fracture; even in patients with such fractures, disc herniation is infrequent and is often considered to be a sequella of trauma. Using magnetic resonance imaging(MRI) we investigated the incidence and pattern of disc injuries by an in 37 patients with fractures of the lumbar and thoracic spines. Discs adjacent to the fracture site were found to be normal in 19 patients(51.4%), but in ten(27.0%), the end plate was disrupted. The disc was ruptured in six patients(16.2%), and had degenerated in two patients(5.4%). Injured discs were found in the three patients with fracture-dislocation and three of the seven(42.9%) with burst fracture, but in none of the 27 with compression fracture. The three lower lumbar discs(L3-4, L4-5, and L5-S1) were found to be normal in 26 patients(70.3%), but had degenerated in seven(18.9%). Incidental asymptomatic disc herniation was found in four patients(10.8%), including one with degenerative spondylolisthesis. There was no traumatic disc herniation in the lower lumbar region. These results suggest that traumatic lumbar disc herniation is quite uncommon, even in the unstable thoracolumbar spinal injuries.

We present a unique case of a brain abscess that occurred secondary to a ganglionic hemorrhage in a 64-year-old man. This abscess appeared to be metastatic after septicemia. Aspiration with antibiotics eliminated this infection.

The purpose of this study is to identify a group of mild head injury patients having lesions on computerized tomography(CT) and to investigate the risk factors affecting the abnormal findings on CT scan. The study was limited to patients 16 years of age and older with a initial Glasgow Coma Scale(GCS) scores of at least 13 at the time of admission. Of a total of 243 patients studied, 156(64.2%) had abnormal CT findings. 49 patients(20.2%) required neurosurgical intervention(craniotomies for hematoma in 33, hematoma in 1 and subdural hygroma in 3). Four patients(2.4%) died of their cranial injury and three died of extracranial causes. The incidence of CT abnormalities for each GCS score was 86.7% in GCS of 13, 68.6% in GCS of 14, and 58.6% in GCS of 5. The factors affecting GCS scores at the time of admission were the presence of loss of consciousness and posttraumatic amnesia. The factors affecting abnormal CT scans were the presence of posttraumatic amnesia and skull fracture. A new lesion of extension of the initial finding on follow-up CT scans was found in 9.3% of 75 patients who underwent follow-up CT scans. Even though routine CT scans for mild head injury patients are not always necessary, these result suggest that all patients admitted to hospital after mild head injury should undergo CT scanning to enable early detection of an intracranial lesion.

Primary malignant melanoma arising from the leptomeninges is a rare entity. We report two cases of primary intracranial melanoma developed in one aged 65 years female and the other 70 years male. One case died 2 years after the operation, and the other case is still living more than 1 year after operation. Both cases seems to have a relatively long survival. The literature on this subject is briefly reviewed.
