A comparative estimation of the combined cortical thickness of various bone sites.

Measurement of the cortical thickness of long bones is the best method of quantitatively diagnosing osteoporosis. Combined cortical thickness (CCT) is as good as, or better than more complicated indices. In osteoporosis studies, the problem lies in finding a physiologically consistent bone site . The CCT of the lower shaft of the humerus showed the lowest coefficient of variation in this homogeneous female population and the addition of both CCT values further reduced the variability. It is suggested that the humeral site is significantly superior to the metacarpal sites and that the variability is small enough to give clinically useful information in the diagnosis of osteoporosis.

Benign hypertrophic gastropathy: ménétrier's disease in childhood and adolescence.

Menetrier's disease (hypertrophic gastropathy) in patients under the age of 20 years is rare. A case is described and the features of the condition found in 11 young patients are discussed. The patients, when seen, are usually in acute abdominal pain and vomiting or edema due to hypoproteinemia is present. Eosinophila was found in half of the recorded cases and the cause in these cases may be due to hypersensitivity. Anemia is common and hypoproteinemia usually found. There is a distinct male predominance and patients are usually Caucasians. Our patient is the second black male youth recorded with this disease. The distinction from adult Menetrier's disease is its benign nature in this age group and complete clinical recovery is the rule. The term benign hypertrophic gastropathy is suggested.

Calcified mucinous adenocarcinoma of the stomach--the CT appearances.

The CT appearances of calcified mucinous adenocarcinoma of the stomach have not been previously reported. This is a rare tumour with a high propensity to calcify, the calcifications typically are small and spiculated. A case is described where the condition was suspected in the plain films of the abdomen and confirmed by CT examination of the stomach.

Granulocytic sarcoma (chloroma) of bone: the CT appearance.

Granulocytic sarcoma (chloroma) is an unusual tumour usually seen in cases of myelogenous leukemia. The tumour is most commonly located in the skull, orbits and sinuses. Extracranial tumours occur mainly in the soft tissues of the body and bone involvement is uncommonly seen and is almost invariably lytic in nature. We describe the first case of CT demonstration of bone involvement by such a tumour. A mixed sclerotic and lytic pattern was seen.

Abdominal wall lipoma--CT and MRI appearance.

Although soft tissue lipomata are common tumours, a large lipoma arising from the deep layers of the abdominal wall would appear to be excessively rare and the site of origin may be difficult to determine. The CT and MRI appearances of such a tumour are described.

Ossicles anterior to the proximal tibia.

Ossicles anterior to the anterior tibia are most usually seen in relation to the tibial tuberosity. While these are usually taken to represent sequelae of previous Osgood-Schlatter disease, they may, on occasion, represent normal variants in ossification of the tuberosity. Ossicles superior to the tuberosity may have similar origins. Representative examples are presented, as is a very large ossicle separated from the anterior tibia by a prolongation of the knee joint space. Theories of causation of such ossicles are discussed.

Scoliosis in young men with spondylolysis or spondylolisthesis. A comparative study in symptomatic and asymptomatic subjects.

While an increased incidence of scoliosis in symptomatic spondylolysis and spondylolisthesis has been established previously, a comparison of its occurrence in symptomatic and asymptomatic individuals has not been performed. The present study is a comparison of symptomatic and asymptomatic young men with analysis as to the incidence of scoliosis. Idiopathic scoliosis was not found and all cases were due to spasm scoliosis or olisthetic scoliosis with the spasm type being much more common. Scoliotic curves were divided into mild (0-9 degrees) and moderate (10-20 degrees). No case of a curve greater than 20 degrees was seen. Scoliosis incidence in asymptomatic individuals without a pars break was 6.65%. In the groups of: (1) asymptomatic unilateral spondylolysis, (2) asymptomatic bilateral spondylolysis, (3) symptomatic bilateral spondylolysis, and (4) asymptomatic spondylolisthesis the scoliosis incidence was similar, ranging from 13.3-23.8%. These figures are significantly higher than those seen in the asymptomatic subjects without a pars break, but they are in the same range as in symptomatic patients without a pars break, suggesting that muscle spasm is the principal cause of the scoliosis.
