    Abstract:
    The purpose of this study was to review the correlation between the imaging studies and the histological findings in the diagnosis of this disease. We retrospectively reviewed 21 lesions in 20 patients (median age, 23.7 years old) who had been diagnosed with cavernous haemangiomas (n=11), capillary (n=6), and mixed (n=3) types. The imaging studies were obtained with plain film radiography (n=20), Tc-99 m bone scans (n=5), angiography (n=7) and magnetic resonance imaging (MRI; n=20). All the patients underwent marginal to wide excision. Based on the imaging studies, the rate of accurate prediction of intramuscular haemangioma using MRI in our study was 90%. Using the preoperative imaging studies and surgical excisions, only one (5%) local recurrence happened 2 years after marginal excision. The remaining patients were free of disease. For the avoidance of recurrence, wide excision is necessary with the help of the imaging studies, which can provide more specific information, making possible the preoperative identification of characteristic features of the tumuor. Le but de cette étude est de montrer la corrélation entre les images radiologiques et les constatations histologiques dans le diagnostic des hémangiomes. Pour cette étude, 21 lésions chez 20 patients (âge moyen 23.7 ans) pour lesquels ont été diagnostiqués un hémangiome caverneux (11), capillaire (6) et mixte (3). Le diagnostic de ces hémangiomes ayant été réalisé par radiographie simple (20), scanner avec technecium (5), angiographie (7) et IRM (20). Tous ces cas ont bénéficié d’une excision large. A partir des images IRM, la prédiction d’hémangiomes intra-musculaires a été de 90%. Seuls 5% des patients présentaient une récidive locale 2 ans après l’excision, les patients restant n’ayant pas présenté de problèmes particuliers. Afin d’éviter la récidive, il est nécessaire de réaliser une excision large à partir du bilan radiographique, scanner, IRM.
