2671/3657. Intracerebral calcification in a case of systemic lupus erythematosus with neurological manifestations. Intracerebral calcification was found in a young child with systemic lupus erythematosus. Vascular lesions characteristic of SLE were widespread and associated with systemic infarcts and multiple infarcts of the brain and spinal cord. The cerebral calcification was also related to blood vessels, but confined to certain regions of the brain. ( info) |
| The value of CT in the easy diagnosis of lipomas and associated anomalies of the corpus callosum, thus avoiding angiography and pneumoencephalography, is reported in five cases. An angiogram was performed in only one of the five cases and provided no additional diagnostic information. ( info) |
2673/3657. Difficult laryngoscopy and tracheal intubation due to calcified stylohyoid ligaments. Two cases of difficult laryngoscopy and tracheal intubation caused by calcified stylohyoid ligaments are presented. Neither patient exhibited a skin crease over the hyoid bone. It is suggested that inability to lift up the epiglottis from the posterior pharyngeal wall be taken as a more useful sign of this condition than the presence of the skin crease. ( info) |
2674/3657. Leydig-cell tumour of the testis. leydig cell tumor of the testis is an uncommon occurrence. A case is reported here which had two interesting features. One was extensive calcification and the other an abundant lipid deposition within the tumour cells. The pathogenesis of calcification is discussed. ( info) |
2675/3657. Focal choroidal calcification. Localized choroidal calcification was detected clinically in two otherwise healthy men. The lesions showed typical features of choroidal nevi. One patient exhibited features suggesting a drusen overlying the nevus. Echography detected choroidal calcification in both cases. A-scan echography revealed a highly reflective choroidal mass attenuating the ultrasound beam. B-scan ultrasonography revealed a dense choroidal mass attenuating the ultrasound beam with focal echoes remaining at low sensitivity. Orbital radiographic and CT scan examination confirmed the echographic findings. ( info) |
2676/3657. Xeroradiographic observations in four patients with chronic renal disease and cutaneous gangrene. Cutaneous gangrene developed in four patients who had chronic renal disease that resulted in secondary hyperparathyroidism and systemic arterial calcification. Three of the four patients showed a unique pattern, by xeroradiography, of extensive medical calcification in subcutaneous arterioles. This noninvasive procedure demonstrated calcium in minute subcutaneous arterioles. parathyroidectomy, conservative local care, and skin grafting resulted in cure of the cutaneous ulcers in two of the four patients.

2677/3657. Metastatic myocardial calcification. A case of metastatic myocardial calcification is reported in a patient with chronic renal failure. The characteristic features are failure to take phosphate-binding antacids on a regular basis, intractable congestive heart failure, atrioventricular block, a calcium phosphate product consistently greater than 60, and sudden irreversible cardia arrest. Arteriovenous fistulae created for haemodialysis appear to be an unlikely cause of cardiac failure. ( info) |
2678/3657. Massive calcification of the mitral annulus in a 17-year-old patient with juvenile rheumatoid arthritis and systemic lupus erythematosis. Mitral annulus calcification (MAC), while a relatively frequent autopsy finding in older patients, is rare in childhood. Such calcification has generally been regarded as a degenerative change and of no clinical significance. Recent studies have shown that MAC may be associated with hemodynamically significant lesions including mitral insufficiency, arrhythmias, heart block, and, rarely, mitral stenosis. We have studied a case of massive calcification in the mitral annulus in a 17-year-old girl with juvenile rheumatoid arthritis and systemic lupus erythematosis. In this case, the MAC was considered secondary to the rheumatoid disease. MAC in younger patients with no history of rheumatic fever or bacterial endocarditis suggests an associated connective tissue disorder. ( info) |
2679/3657. Metastatic calcification: the role of bone scanning. Metastatic calcification involving the lungs and stomach was demonstrated in 3 patients by bone scans. In one patient, postmortem studied five days later confirmed the findings. Follow-up scans in 2 patients, demonstrating improvement in one and worsening in another, paralleled the clinical course.

2680/3657. Calcifications of the hip in infants and children. New cases and long-term follow-up. 10 cases of calcification of the peripheral cartilaginous contour of the femoral head in infants are reported. In 7 cases calcification were discovered by chance at a radiological examination done for another purpose. In 3 cases the examination was done for limp or pain in the hip. In this material are included the long term follow-up of the first 4 cases reported by one of us in 1968. The follow-up in our series ranges from a few months to 15 years. The clinical sequelae are minimal at the moment: slight decrease of abduction and internal rotation. The radiological follow-up shows a slow disappearance of calcification, a premature fusion of the physis, a coxa magna, a broadening and shortening of the femoral neck. These residual radiological anomalies, in spite of a good clinical state at the moment, are worrying for future of these hips. The etiology is unknown, but these calcifications are acquired and there are good reasons to think they are iatrogenic, probably secondary to an inadvertent injection into the hip joint at the time of an intravenous femoral infusion of a drug toxic for the hip cartilage. It seems reasonable to avoid the femoral route for intravenous infusion of drugs in newborns and infants. ( info) |
