They may be identified clinically as palpable masses or incidentally in radiologic examinations. There are many diagnostic possibilities, including congenital, neoplastic, inflammatory and traumatic lesions. The purpose of this study is to illustrate the main calvarial lesions through MR imaging, their signal intensity and extension to neighboring sites. METHOD: A retrospective analysis of 81 cases, from November 1996 to July 2001, was conducted. The examinations were performed on a 1.5 T equipment and each one of the cases was pathologically proven. RESULTS: The results were: dermoid cysts [4 cases (5%)], epidermoid cysts [2 cases (2.5%)], cephalocele [14 cases (17.5%)], sinus pericranii [3 cases (3.7%)], leptomeningeal cysts [4 cases (5%)], Langerhans cell histiocytosis [10 cases (12.5%)], lipoma [4 cases (5%)], fibrous dysplasia [13 cases (16.2%)], osteoma [8 cases (10%)], hemangioma [1 case (1.2%)], meningioma [3 cases (3.7%)], chondrosarcoma [5 cases (6.2%)], hemangiosarcoma [1 case (1.2%)], multiple myeloma [3 cases (3.7%)], sarcomatous transformation of Paget disease [1 case (1.3%)], and metastasis [5 cases (6.2%)]. CONCLUSION: MRI identifies bone marrow abnormalities and invasion of adjacent tissues at an early stage. Therefore, it is an essential method when it commes to properly evaluating calvarial lesions.<\/jats:p>","DOI":"10.1590\/s0004-282x2003000400001","type":"journal-article","created":{"date-parts":[[2007,9,27]],"date-time":"2007-09-27T22:29:47Z","timestamp":1190932187000},"page":"521-532","source":"Crossref","is-referenced-by-count":37,"title":["MR imaging for evaluation of lesions of the cranial vault: a pictorial essay"],"prefix":"10.1590","volume":"61","author":[{"given":"L\u00e1zaro","family":"Amaral","sequence":"first","affiliation":[{"name":"Hospital Benefic\u00eancia Portuguesa,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miriam","family":"Chiurciu","sequence":"additional","affiliation":[{"name":"Hospital Benefic\u00eancia Portuguesa,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jo\u00e3o Ricardo","family":"Almeida","sequence":"additional","affiliation":[{"name":"Hospital Benefic\u00eancia Portuguesa,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nelson Fortes","family":"Ferreira","sequence":"additional","affiliation":[{"name":"Hospital Benefic\u00eancia Portuguesa,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Renato","family":"Mendon\u00e7a","sequence":"additional","affiliation":[{"name":"Hospital Benefic\u00eancia Portuguesa,  Brasil"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"S\u00e9rgio Santos","family":"Lima","sequence":"additional","affiliation":[{"name":"Hospital Benefic\u00eancia Portuguesa"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"530","reference":[{"key":"ref1","first-page":"96","article-title":"Imaging evaluation and clinicopathologic correlation of mass lesions involving the calv\u00e1ria.
