Cervicothoracic MRI. (a) Sagittal T1 and (b) sagittal T2-weighted image show isointense extradural mass (yellow arrow) in spinal canal lying from C6 until T1 levels. (c) Axial T2-weighted image shows severe compression of the cord due to posterior extradural mass (yellow arrow).

The MR showed a posterior, extradural, and isointense soft-tissue mass, measuring 1.0 x 0.7 x 3.0 cm extending from C6 to T1 resulting in severe cord compression that did not enhance with contrast [Figures 1 and 2].
Cervicothoracic MRI with contrast. (a) Sagittal T1 MRI show posterior mass (yellow arrow) and (b) axial T1 MRI show an extradural mass (yellow arrow) that was not significantly enhanced after injection of contrast agent.

The MR showed a posterior, extradural, and isointense soft-tissue mass, measuring 1.0 x 0.7 x 3.0 cm extending from C6 to T1 resulting in severe cord compression that did not enhance with contrast [Figures 1 and 2].
Intraoperative finding showed extradural tumor with well demarcated border (white arrow heads) that was very adherent to duramater. After resection of the mass, it showed white and intact duramater (green arrow).

He underwent a C6-T1 laminectomy for gross total tumor removal followed by an instrumented C6-T2 fusion [Figures 3 and 4].
Instrumentation was implanted from C6 to T2 level.

He underwent a C6-T1 laminectomy for gross total tumor removal followed by an instrumented C6-T2 fusion [Figures 3 and 4].
Histopathology revealed Touton giant cells (a) (b) (c) (black arrows) on a background of lymphocytes and histiocytes, corresponds to Xanthogranuloma.

The gross examination revealed brownish-white, soft-tissue fragments (i.e., largest measurements of 2.6 x 1.9 x 0.6 cm), while the microscopic showed fibrous connective tissue with extravasation of erythrocytes, xanthoma cells, lymphocytes, histiocytes, and Touton giant cells [Figure 5].
