Background. The reconstruction of femoral shaft defects after tumor resection involves joining healthy bone fragments with plates or intramedullary rods, using methyl metacrylate cement or bone grafts. Material and methods. 50 patients (35 females and 15 males) were operated over the last 24 years. The patients' ages ranged from 12 to 80 years (mean 56). Results. There were 37 bone metastases, ...

The upper-middle tibia is the mult iple growth section of benign and malignant neoplasm, which is easy to result in bone defect after tumorectomy and it is a serious problem in orthopaedics. We reported a case about a huge benign or potential malignant tumor( giant cell tumor of bone) in upper-middle tibia and contrasted the advantage between the jade prosthesis and the allograft. Initially, th...

Although vertebral column is recognized as the most common site for bony metastasis in patient with systemic malignancy, intramedullary metastases to the spinal cord is infrequent. Between 5% 10% of cancer patients develop spinal metastasis during the course of their diseases. Intramedullary tumors are rare, comprising 3.5% of spinal metastasis. Most metastatic spinal lesions (70%) are found at...

BACKGROUND AND PURPOSE Only a few reports on intramedullary tumors of the spinal cord using PET have been published. We report findings of PET by using [(18)F] fluorodeoxyglucose and [(11)C] methionine and discuss the usefulness of the findings in patients with intramedullary tumors of the spinal cord. MATERIALS AND METHODS PET/CT was performed in 9 patients with intramedullary tumors of the ...

INTRODUCTION Epidermoid cysts are known as embryonic or acquired ectopic aberrations of the ectoderm. To the best of our knowledge, there are only a few reports of elderly onset intramedullary epidermoid cysts. We report a case of elderly onset intramedullary epidermoid cyst at the conus medullaris. CASE PRESENTATION A 63-year-old Japanese woman working as a farmer presented with slowly progr...

We report a rare case of a thoracic intramedullary subependymoma in a 37-year-old woman. The patient developed a monoparesis of the right leg after a subtotal resection of the tumor. During the 30 months of follow-up the neurological deficit improved and the patient remained symptom free without progression of the remnant tumor. A complete resection of the tumor is usually curative with improve...

Study Design Case report. Objective Malignant mesothelioma (MM) is an uncommon tumor of the pleural epithelium with a predilection for local spread into adjacent tissues. The sarcomatoid type accounts for ∼10% of MM cases and is associated with poorer survival than the epithelioid, desmoplastic, and biphasic types. MM commonly presents with involvement of the vertebral body or epidural space. H...

BACKGROUND There are several non-neoplastic lesions which mimick intramedullary spinal cord neoplasm in their radiographic and clinical presentation. These can be classified as either infectious (TB, fungal, bacterial, parasytic, syphilis, CMV, HSV) and non-infectious (sarcoid, MS, myelitis, ADEM, SLE) inflammatory lesions, idiopathic necrotizing myelopathy, unusual vascular lesions and radiati...

The MR imaging features of a paraganglioma of the cauda equina with associated spinal cord cysts are presented. MR imaging showed the tumor to be isointense with the spinal cord on all pulse sequences and to enhance homogeneously. The intramedullary cysts had increased signal intensity on proton density- and T2-weighted images, and involved the cervical and thoracic regions.

Central neurocytoma is a relatively rare tumor of the central nervous system. Young adults are most commonly affected, with a similar incidence in males and females. The tumor is predominantly occurs in the ventricular system of the brain. The tumor is benign and exhibits a good response to surgical resection and radiation therapy. The typical central neurocytoma occurs in the supratentorial ve...
