The discussion considers the diagnostic interest of psammoma bodies in central nervous system tumors, as well as its histogenesis. The different points of view explaining biological mineralization in other territories of the organism are analyzed, as well as the formation of psammoma bodies, comparing the morphologic data obtained in this study. It is concluded that the mineralization of the psammoma bodies is induced principally by the collagen fibers synthesized by the meningocytes and that the form of mineralization is spherical and growth is radial, controlled by the tumoral cells.</p>","PeriodicalId":8654,"journal":{"name":"Archivos de neurobiologia","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12661457","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We describe a patient diagnosed of SLE who developed a psychotic clinical picture followed by generalized epileptic seizures within a context of diffuse lupus encephalopathy. On the neurological examination, she presented cortical blindness, generalized piramidalism and extrapiramidal rigidity. Various electroencephalographic recordings showed signs of diffuse cerebral involvement predominantly in posterior regions. Cerebrospinal fluid analysis showed a slight increase of IgG without oligoclonal bands and a positive anti-DNA antibody with an homogeneous pattern. Sequential CT images were carried out demonstrating hypodense areas initially in the occipital regions that extended progressively to the temporal, parietal and finally to the frontal lobes, with a moderate mass effect on the lateral ventricles and with no contrast enhancement. The images of the lesions on the CT disappeared completely with the adequate treatment as the symptomatology resolved. A MRI and cerebral angiography were performed when the patient recovered. Both MRI and angiography showed no alterations. We consider that this neuroradiological finding is exceptional, because of its total resolution.
