Expansive

Covering a wide area in terms of space or scope; extensive.

Intramedullary expansive lesion compatible with neoplasia of about 13.4 cm in length, originating at the level of C4-C5 up to D4-D5, presenting cranial and caudal cystic areas and a solid component at the Th1-Th3 level presenting enhancement of about 43 mm in diameter length and another solid component at the C5 level of 11 mm in length. At the caudal level, the lesion presents a hemosiderin cap or bleeding, slightly hyperintense on T1 and hypointense on T2. Given its location and radiological appearance, it suggests that it is an ependymoma. Extensive spinal cord edema proximal and distal to the lesion is associated, extending from the tectum to T8. Leptomeningeal enhancement along the entire spinal cord and some roots of the cauda equina (more evident in right L5) compatible with tumor extension along the neuraxis. Vertebral lesion affecting the pedicle and the left lamina of Th8 that appears slightly hypointense on T1 and hyperintense on STIR and T2, with contrast enhancement. The lesion appears to present some hypointense septum on T2, it could present some medulla foci inside it, so it probably corresponds to an atypical hemangioma.
