T2 T1 Gadolinium L1
11/12 L1~L3 Laminectomy with grossly total tumor removal
Hospitalization course 11/12 L1~L3 Laminectomy with grossly total tumor removal Lower extremities weakness or numbness x Mild low back pain 11/19 Discharge PATHOLOGICAL DIAGNOSIS: Angiolipoma
Angiolipoma Rare, benign mesenchymal tumors In 2002 76 case s had histologically confirmed 72 cases were extradural & 4 cases intramedullary Containing mature adipose tissue + abnormal vascular elements Uptodate online edition
Angiolipoma • Liebscher: first described in 1901 • Spinal angiolipomas : 0.14-1.2% of all spinal axis tumors • Approximately 2-3% of extradural spinal tumors Australasian Radiology (2002) 46, 84–90
Angiolipoma Lin & Lin Subdivide into 2 types; noninfiltrating & infiltrating Infiltrating -lesions primarily involve the spine More common in women (noninfiltrating) infiltrating type isseen equally in male and female patients Most commonly diagnosed during the 5th decade The Spine Journal 7 (2007) 739–744 The Spine Journal 7 (2007) 739–744 Uptodate online edition
Angiolipoma Most occur in the spinal canal usually in the thoracic level (mid-thoracic spine) almost all are epidural Intradural lesion have a relatively brief clinical course Intraduralv.s extradural: 5.8 vs 25.8 months Uptodate online edition
Angiolipoma Arise from the posterior epidural space at the thoracic levelsand usually extend over three to four vertebral bodies Spinal cord compression & back pain is a frequent initial symptoms The Spine Journal 7 (2007) 739–744 Uptodate online edition
Predisposing factors Weight gain in pregnancy was observed to increase the risk of spinal angiolipoma Obesity is occasionally reported in patients with spinal angiolipoma The Journal of Spinal Cord Medicine Volume 31 Number 3 2008
MRI features The MRI differential diagnosis for an intraspinalhyperintense mass on a T1-weighted image includes lipoma, lipomatosis, angiolipoma, myelolipoma, subacutehaematoma, dermoidcyst and melanoma Australasian Radiology (2002) 46, 84–90
MRI features Complete suppression of high signal intensity on fat-suppressed T1-weighted images exclude melanin or methaemoglobin Contrast enhancement exclude lipoma and lipomatosis Australasian Radiology (2002) 46, 84–90
MRI features Complete suppression of high signal intensity on fat-suppressed T1-weighted images exclude melanin or methaemoglobin Contrast enhancement exclude lipoma and lipomatosis The combination of suppression of fat signal and contrast enhancement is the hallmark of angiolipoma Australasian Radiology (2002) 46, 84–90
Take home message Benign mature adipose tissue with abnormal vascular MRI diagnosis: T1: hyperintense Fat-suppressed: high signal intensity Contrast: enhancement Operation: Released spinal cord to prevent nerve injury Sample for diagnosis
Quiz 1 • Hallmarks of Spinal Angiolipoma? • Occurrence in middle-aged • Often female patients • Always localization of thoracic spine • Almost intradural
Quiz 1 • MRI features of Spinal Angiolipoma , except? • T1: hyperintense • Fat-suppressed: high signal intensity • Contrast: enhancement • All of above
Which diagnosis is not favor? Lipoma Angiolipoma Myelolipoma Meningioma
