Abstract

A case of retroperitoneal benign schwannoma is presented; in addition, 133 cases of retroperitoneal schwannoma reported in Japanese literature are studied. In our series 66 per cent of the cases were found to be cystic. Therefore, the cystic change may be one of the preoperative features of schwannomas, because other types of retroperitoneal tumor do not frequently form cysts. Furthermore, the necessity of postoperative electron microscopy for accurate histologic diagnosis is discussed.

    Schwannomas are tumors that arise from the nerve sheath, commonly in head, neck, and extremities. They rarely manifest in the retroperitoneal area [1]. Approximately, 0.3–3 % of schwannomas are found in the retroperitoneum [2].

    Kim et al. [24] described the imaging features of 6 schwannomas, all of which were well-demarcated spherical masses with prominent cystic change. Takatera et al. [25] in a review of the Japanese literature found 133 reported cases of schwannoma, of which 66% showed cystic change. But neither of them had carefully studied the specific morphology of the cystic component within GSS.

    Citation Excerpt :

    The CT-scan finds a well-defined lesion, whose density depends on the lesional rearrangements. Whether cystic, necrotic, haemorrhagic or in the form of calcification, the larger the tumour the more marked the rearrangements [13,14]. The CT-scan guided biopsy may not contribute a great deal in view of these rearrangements and remains debatable [4].

    Cystic degeneration or calcification is the end-stage degenerative change of a schwannoma, which is considered to be a result of a long-standing tumor growth [26]. About 66% of retroperitoneal schwannomas are found to be associated with cystic degeneration, which is originally considered to be a characteristic change of schwannomas [27]. However, cystic degeneration or necrosis cannot be used reliably to distinguish between benign and malignant retroperitoneal tumors because this change was also commonly observed within malignant retroperitoneal tumors [28].

    Targetlike central enhancement may also be seen.67 Larger schwannomas are more likely to undergo degenerative changes, including cyst formation (in up to 66%), calcification, hemorrhage, and hyalinization (Fig. 10).19,68 Ancient schwannoma refers to a long-standing lesion with advanced degenerative changes.69,70
