Involvement of temporomandibular joint (TMJ) in rheumatoid arthritis (RA) patients is described, but the incidence varies greatly. In this study our aim was to determine the frequency and character of TMJ involvement in RA patients asymptomatic for this joint, to investigate the relationship with disease activity, and to evaluate the early diagnostic value of imaging techniques. Twenty patients were included in this study, ten were evaluated with computed tomography (CT) and ten with magnetic resonance imaging (MRI). Among the 20 patients 45% had TMJ involvement detected by imaging techniques. The most frequent pathological signs were osteophyte formation, erosion of the mandibular condyle and decreased joint space (40%). Age, duration of disease, number of swollen joints. CRP and RF levels were found to be correlated with TMJ involvement. It is concluded that TMJ involvement may be detected even in asymptomatic patients with RA and there is a positive correlation between the severity of disease and involvement of TMJ.
The authors present an extremely rare case of secondary multiple cerebral echinococcosis caused by presumed intracerebral and arterial embolism of cardiac hydatidosis in a 7-year-old girl. The first manifestations were symptoms of raised intracranial pressure. Unfortunately, before the primary ruptured echinococcosis cyst was detected in the myocardium of the left ventricle, the patient underwent nine operations over an 8-year period for hydatid embolism affecting the brain and the femoral artery and was treated with concurrent mebendazole therapy. The combined therapy would not have been successful without removal of the intracardiac hydatid cyst. This case is unusual because of the multiplicity of intracranial hydatid cysts and its embolic origin from cardiac echinococcosis. The present case is believed to be the first one in which the development of an embolism in the brain was studied by magnetic resonance imaging.
Multiple meningiomas are relatively rare tumors without known neurofibromatosis. In this paper, such eight cases of multiple meningiomas as described by CUSHING and EISENHARDT are presented. Certain aspects of diagnosis and surgical management of this rare condition are discussed with particular emphasis on the importance of the distinction among multiple meningioma, meningiomatosis, or recurrences of these tumors. Fortunately, many of these patients tolerate multiple surgical interventions well, although the removal of these tumors in critical areas is a difficult problem. Thus, we think that it is important to examine and supervise all patients who have had a meningioma for a possible occurrence of a second meningioma.
Acquired torticollis is a symptom of an underlying disorder. It requires a thorough, meticulous search for the cause, because some of the problems associated with torticollis, such as posterior fossa tumor, can be life-threatening.
The authors report their experience with 30 adult patients with Budd-Chiari syndrome (BCS), which is a rare and serious disorder, characterized by hepatic outflow obstruction caused by many different conditions. The diagnosis was based on the clinical data, ultrasonography (US), vena cavography and hepatic venography, computed tomography (CT), and liver biopsy. Behçet's disease (BD) was found in 10 patients with BCS as an underlying disease. Two patients used oral contraceptive drugs, 2 had liver tumor hepatocellular carcinoma and liver lymphoma, and 1 patient had chronic lymphocytic leukemia. Despite full investigation, the authors could not find any obvious underlying cause in the other 15 patients. The results suggest that (1) BCS must be considered as a possible complication in patients with Behçet's disease when they have hepatomegaly even if there were no cardinal manifestations of the disease at the time of admission, and BD is the most common etiologic factor in BCS (33%) in Turkey, where the incidence of Behçet's disease is relatively high. (2) Anti-aggregant treatment seems to be effective in many instances. (3) There were space-occupying lesion-like appearances in the liver of 7 cases by CT and US examination in the acute stage, and these disappeared on the follow-up CT and US in 5 patients but continued in 2. BCS should thus be differentiated from other liver lesions. (4) There were other great-vessel involvements in 43% of the cases, mostly venous, but only 1 pulmonary arterial occlusion.
Presacral space enlargement may be the first sign of certain diseases. The normal width of the presacral space has not been widely investigated and in all previous studies was calculated from lateral radiographs obtained at barium enema examination. Our study determined the normal width of the presacral space on MRI and investigated a possible difference between men and women. The width of the presacral space was measured retrospectively from sagittal T2-weighted MR images of 193 patients (87 males; 106 females, aged 18-83 years). Presacral space width was measured separately for S1, S2, and S3 vertebral levels from the anterior surface of the vertebral bodies to the closest part of the posterior wall of the rectum. Differences between male and female subjects were analyzed by t-tests. Normal mean widths of the presacral space in men and women were 16.2 mm and 11.9 mm for S1, 14.9 mm and 11.2 mm for S2, and 13.0 mm and 10.6 mm for S3, respectively. Measurements of the presacral space width in men were significantly larger than in women at all three levels (P < 0.001 for S1, P < 0.001 for S2, P = 0.006 for S3). In summary, the presacral space width measured on MRI was found to be significantly larger in the male than in the female population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
