Solitary involvement of the fourth thoracic vertebral body with eosinophilic granuloma and development of incomplete paraparesis

Eosinophilic granuloma of the spine: early spontaneous disappearance of tumor detected on magnetic resonance imaging. Case report

Two cases of eosinophilic granuloma (EG) of the spine associated with neurological deficits are presented. The patients were treated conservatively by using external fixation with a brace as well as bed rest. Neurological deficits and pain diminished and finally disappeared as the tumor mass decreased in size, as seen on magnetic resonance (MR) imaging. During the 5-year follow-up period no recurrence of the tumors was detected on MR images. Surgical treatment for spinal EG in children presenting with typical vertebra plana is not recommended except for those with severe or progressive palsy and for those in whom the disease requires differential diagnosis.

Cervical spine cord compression by eosinophilic granuloma. Case report

Eosinophilic granuloma is a term reserved for the most often and benign form of disorder known as Langerhans cells histiocytosis. It is a disease of children and adolescents that very rarely affects adults, representing the localized form of a pathological proliferation of histiocytes in bones, like skull and long bones. Vertebral involvement is uncommon, approximately 8% of the cases, being the cervical localization the least affected. Moreover, the involvement of the spinal cord and roots remains a rare occurrence. Only five cases characterized by signs of cervical spinal cord compression have been reported. We report the sixth case in a 42-year-old-man who evolved with resolution of symptoms, and has remained asymptomatic after treatment. The clinical, radiological and histological features and, also, the value, in selected cases, of surgical treatment followed by low-dose radiation therapy is discussed. A review of the pertinent literature is also presented.
