[A rare neurogenic tumor with thoracic growth].

Of 70 operated mediastinal tumors, 15 were neurogenic tumors, one of them clepsydra-shaped, which manifested from the very beginning with spastic paraparesis of the legs. The treatment consisted in a two-steps surgery, the first at the Neurosurgical Clinical of Iaşi (laminectomy and ablation of the rachidian tumor) and the second one, one month later, at the I-st Surgical Clinic of Iaşi (excision of mediastinal tumor and parenchymal bridge within the conjugation hole). The microscopic examination confirmed the diagnosis of neurinoma (schwannoma) Antoni A and B with haemorrhagic areas. Examined at one year interval, the patient was clinically cured with normal thoracic aspect. The clinical peculiarities and therapeutical possibilities of the clepsydra-shaped neurogenic mediastinal tumors are detailed.
