case_images: The CT scan with contrast revealed a 2.0 cm x 1.8 cm x 2.4 cm nodule in the left retroperitoneum, displaying inhomogeneous enhancement, the mean Hounsfield unit (HU) before enhancement was 12.9 HU, while the value subsequent to enhancement was 39.2 HU (Figure 1).
case_images: Two tumor components visible at low magnification (A). Schwannoma lesions in the form of round-like nodules (B). Ganglioneuroma lesions as diffuse lamellar structures (C). Well-demarcated nodular cell tumor (left side) and nerve sheath tumor (right side) (D). Schwannoma consists of sparse and dense areas (E). Dilated vascular plexus visible within the sparse area of the schwannoma, resembling cavernous hemangioma structure (F). Mucinous metaplastic lipid cells and hemosiderin-containing components are seen in the tumor of schwannoma (G). Ganglion cells have abundant cytoplasm and large, round, or oval nuclei with 1-3 nucleoli (H).
