The authors present an exceptional case of chemodectoma jugulare with important invasion of the skull base involving all the cranial nerves on one side and conforming Garcin's syndrome. Practically all the possible ways of spreading were followed by the tumor, with involvement of the posterior, middle and anterior fossas of the skull base and also orbit, middle ear and neck. The clinical and histopathological difficulties in the diagnosis, especially when the chemodectoma has only neurological signs, are stressed. The association of otologic symptoms makes the diagnosis easier. The patient had an early onset of the symptoms and a rapid evolution considering this type of tumors. The appearance of goitre in this patient is a sign of endocrine disturbance, which is occasionally associated with these tumors. Apparently this chemodectoma was not a secreting tumor, since the blood pressure values were normal. No signs of multicentricity or metastatic growths were detected. The radiological studies, and especially computerized tomography scanning, gave precise information about the spreading of the tumor. The authors consider that the knowledge of this entity is important in order to arrive at a correct diagnosis.

La presentacion esta basada en 35 casos de quiste hidatico diagnosticados y corroborados quirurgicamente, que se estudiaron durante un periodo de 18 meses en el Centro de Tomografia Computada del Sanatorio Larghero.El quiste hidatico no complicado (hepatico o pulmonar) se presenta como una imagen hipodensa (0 a 10 uH) homogenea, de forma redondeada y limites netos. Las complicaciones vistas incluyen: 1) Infeccion que se traduce en un aumento de la densidad intraquistica en algunos casos aparicion de tabiques e irregularidad del contorno. En el pulmon se ven los fenomenos inflamatorios del parenquima circundante.2) Vesiculizacion, aparicion de vesiculas hijas y contorno polilobulados.3) Multiplicidad 4) Hidatidosis secundaria intraperitoneal. 5) Transito hepato-bronquico. 6) Hidatidosis pleural. En todos los casos se determino exatamente la cantidad de lesiones, el tamano y topografia de cada una de ellas
