title: [Diagnosis of retroperitoneal and intrathoracic Schwannomas (author's transl)].
abstract: Retroperitoneal and intrathoracic Schwannomas are difficult to diagnose in the preoperative stage. The following methods of examination may be used: 1. X-ray examinations to exclude diseases of the internal organs and to establish displacements.--2. Computertomography to determine localisation and size of the tumour.--3. Immediate section for microscopic examination under surgery to determine the dignity of the tumour and needlebiopsy with histological and cytological examination to obtain an exact diagnosis.
