Abstract
in English, French

Intramedullary lipomas are rare benign lesions accounting for approximately 1% of bone marrow cancers. We report a new case of histologically confirmed non-dysraphic intramedullary lipoma. The study involved a 46-year old female patient who had undergone surgical biopsy for medullary lipoma 6 months before and who did not have radiological reports prior to this surgery. She suffered from rachialgias, sensory disorders, difficulties to walk and recently aggravated muscular weakness. Medullary MRI objectified well-defined mass presenting hypersignal on T1 and on T2 measuring 8cm x 2.5cm in the conus terminalis. Magnetic resonance imaging is the gold standard for the exploration of intramedullary lipomas. It allows early diagnosis as well as surgical management before the onset of irreversible neurological complications.

Les lipomes intramédullaires sont des lésions bénignes rares qui représentent environ 1% de l'ensemble des tumeurs de la moelle épinière. Nous rapportons un nouveau cas de lipome intramédullaire non dysraphique confirmé histologiquement. Il s'agissait d'une patiente âgée de 46 ans ayant bénéficié d'une biopsie chirurgicale pour un lipome médullaire il y a 6 mois. Nous ne disposons pas de documents radiologiques antérieurs à cette chirurgie. Elle présente actuellement des rachialgies, des troubles sensitifs, des troubles de la marche et une faiblesse musculaire d'aggravation récente. L'IRM médullaire objective une formation en hypersignal T1 et T2 bien limitée de 8cm x 2,5cm prenant le cône terminal. L'imagerie par résonance magnétique occupe une place primordiale dans l'exploration des lipomes intramédullaires, elle permet le diagnostic précoce et ainsi une prise en charge chirurgicale avant la survenue de complications neurologiques irréversibles.

Keywords: Intramedullary lipoma; non dysraphic intramedullary; nuclear magnetic resonance imaging.
