BACKGROUND Simple or unicameral bone cysts are common benign fluid-filled lesions usually located at the long bones of children before skeletal maturity. METHODS We performed demineralized bone matrix and iliac crest bone marrow injection combined with elastic intramedullary nailing for the treatment of simple bone cysts in long bones of 9 children with a mean age of 12.6 years (range, 4 to 1...

Introduction: Solitary Fibrous Tumor (SFT) is a rare tumor that initially was thought to arise from visceral tissue. Later reports documented its occurrence in central nervous system tissue, with most located intracranially. Few reports have mentioned intraspinal SFTs, with the majority being extra-medullary. In this report, we describe a rare presentation of intramedullary SFT. Case descriptio...

A diaphyseal, intramedullary, highly sclerotic lesion presenting as a pathological fracture, without a periosteal reaction or an appreciable soft tissue component on radiographs was investigated. A discrepancy between the MRI and histopathological findings led to marginal excision of the lesion only to reveal later that it was a sclerotic variety of osteosarcoma. Such a presentation has not bee...

Perimedullary arteriovenous fistula (AVF) shunts occur on the spinal cord surface and can be treated surgically or by endovascular embolization. In contrast, the nidus of an intramedullary arteriovenous malformation (AVM) is located in the spinal cord and is difficult to treat surgically or by endovascular techniques. The benefits of radiotherapy for treating intramedullary AVM have been publis...

Plasmacytoma of the calvarium is very rare, accounting for the 0.7 % of all plasmacytomas [1–5]. The most common locations are the thoracic and lumbar spine (30–40 % of cases). Involvement of the hip, femurs, and ribs is less frequent [6]. Plasmacytoma of the calvarium can be indistinguishable from other lytic lesions, especially metastatic disease. Meningioma, eosinophilic granuloma, and dermo...

A 31-year-old man presented with acute onset of paraplegia. The patient's history was significant for thyroid carcinoma that had been treated 2 years earlier by thyroidectomy. A magnetic resonance imaging scan showed an enhancing intramedullary lesion at T7-8. Patient underwent surgical treatment and a tumor with hematoma was resected via posterior midline myelotomy. Postoperatively, the patien...

Background: Melanocytoma is a rare pigmented central nervous tumor. In the spine, it may develop in meninges, extramedullary or intramedullary. It usually has good outcome after total excision.
 Case report:
 A 40-year-old male patient was admitted to our hospital 12 years ago with 3-month history of progressive neck pain and difficulty walking. On clinical examination, he showed uppe...

Although it is quite rare, second primary neoplasms in cancer patients may present with the signs and symptoms of malignant spinal cord compression. Primary spinal cord tumours in the cancer patients may be deceptive and considered as the recurrent first cancer. Therefore, it should be precisely differentiated and appropriately managed. We report such a case of intramedullary ependymoma of the ...

Post-traumatic osseous cystic lesions are a rare complication in children. An aetiology of intramedullary fat seepage through the damaged bone cortex and its entrapment within the subperiosteum has been proposed. These lesions run a benign course and usually resolve spontaneously. The presence of fatty marrow gives it a distinct appearance which aids in its diagnosis and differentiation from ot...
