An Unusual Tumor of The Neck and Mediastinum: Lipoblastomatosis Resulting in Paraparesis
xmlui.mirage2.itemSummaryView.MetaDataShow full item record
Lipoblastornatous tumors are quite rare neoplasms deriving from embryonic white fatty tissues, most often seen in infancy and childhood. Lipobtastoma is the focal and well-circumscribed type, whereas tipoblastomatosis is the more infiltrating type of lipoblastomatous tumors. We present a 14-month-otd mate infant presenting with a mediastinal mass showing paraparesis, who had previously undergone the removal of the cervical part of this mediastinal mass. We removed the mediastinal part of the mass with a posterotateral thoracotomy which proved to be a tipobtastomatosis. We emphasize that this very uncommon tumor located at the neck and mediastinum should be included in the differential diagnosis of infants having gait disturbance.
