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.

Maligant melanomas of the oral or nasal cavity, and the vulvovaginal area are relatively common among the melanomas of non-ocular mucosa. But, primary malignant melanoma arising in the mucosa of the palatine tonsil is rare. We present a case of primary malignant melanoma arising in the mucosa of the palatine tonsil. A 36-year-old male was admitted for evaluation of a recurrent sore throat. Tonsillectomy was performed on the basis of clinical suspicion of chronic tonsillitis. Grossly, the left tonsil was focally dark. Microscopically, the tonsillar mucosa was diffusely infiltrated with tumor cells. Tumor cells revealed numerous melanin pigments. Intraepithelial nests of tumor cells were noted, but pagetoid spread of tumor cells was not found. Tumor cells were positive for S-100 protein and HMB45 stain. There was no evidence of melanoma in the skin or eye.

Nodular cystic fat necrosis, first described by Przyjemski and Schuster, is a peculiar form of encapsulated necrosis of subcutaneous fat characterized by totally or near-totally encapsulated necrosis of fatty tissue in which clusters of nonviable adipocytes are surrounded by condensed fibrous tissue. We report two cases of nodular cystic fat necrosis associated with history of trauma about the site of the lesion. Each lesion was a subcutaneous movable nodule on buttock (case 1) and shin (case 2) which has evolved over months. Both cases showed possible relation to multiple intramuscular injection or direct trauma injury. Pathologically, encapsulated nodule showed a characteristic feature of nodular cystic fat necrosis which composed of the ghosts of anucleated adipocytes showing fairly well-preserved outline.

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.
