Kerolus and others (1) described an 83-year-old woman with an intradural extramedullary
cavernous lymphangioma at the level of T5-T8, which demonstrated low- to iso-signal on T1 and high signal on T2 as well as homogenous cyst enhancement on Gad injection.
They are found most commonly in intradural extramedullary
and intramedullary locations of the thoracic spine and cauda region (52).

tumor: a case report," Journal of Medical Case Reports, vol.
MRI of the cervical spine revealed an intradural extramedullary
cystic mass lesion ventrally to the spinal cord at the C3 to C4 level with the spinal cord tightly stretched out over this ventral cyst (Figure 1).
Contrast enhanced cervical spine MRI demonstrated an enhancing intradural extramedullary
T1 isointense and T2 hypointense mass at the level of C2-C3, anterior to cervical spinal cord and resulting in severe spinal canal stenosis.
Cavernous Angioma: Case Report.
His topics include congenital and developmental abnormalities of the spinal cord or vertebrae, intradural intramedullary lesions (spinal cord lesions), dural and intradural extramedullary
lesions, multifocal lesions and/or poorly defined signal abnormalities involving the spine, and traumatic lesions involving the spine.
MRI of the spine indicated a well-circumscribed mass with 6 cm x 1.5 cm x 2 cm in size at the level of T11-T12, in the intradural extramedullary
Magnetic resonance imaging (MRI) of lumbar spine revealed intradural extramedullary
lesion measuring 6.1 x 2.0 cm at L1-2 level near the right kidney which was hypointense on T1- and hyperintense on T2-weighted sequences (Figures 3 and 4).
In the intradural extramedullary
space, primary tumours such as neurofibroma and meningioma are relatively common.
(Table 1, 2) Intraoperatively 44 (91.6%) were intradural extramedullary
, 2 (4%) were epidural and 2 (4%)
Computed tomography of the thorax revealed an intradural extramedullary
mass, approximately 2 cm in diameter, at the T5-6 level (Figure 1).
