Chordoma is a rare bone tumour with a known intrinsic heterogeneity. Here, we address this tumour heterogeneity in a new cell culture model for tumour diversity and progression in chordoma. The three cell lines U-CH17P, U-CH17M, and U-CH17S were established from a primary sacral chordoma and its derived metastases, a soft tissue and a skin metastasis, respectively. The lesions had divergent differentiation patterns which are conserved in the derived cell lines making them a suitable in vitro model for the analysis of tumorigenesis in chordoma...

BACKGROUND: Combination of surgery and radiotherapy in the treatment of primary spine tumour can be indicated in some cases where a satisfactory oncological margin cannot be achieved. The presence of metal hardware has always limited post-operative radiotherapy due to the scattering effects of ionizing radiation or particles. The use of a fixation system (including rods and screw) fully made in PEEK embedded Carbon fiber (CFR-PEEK) could make easier and more effective the post-operative radiotherapy as it is radiolucent and does not interfere with ionizing radiation and accelerated particles...

Sacral-iliac fixation techniques may be indicated in the management of various lumbosacral pathologies including spinal degeneration, infection, tumour resection, fracture, pseudarthrosis, correction of spinal deformities involving long fusion constructs to the sacrum and cases with poor sacral fixation. There are a number of options for lumbosacral fixation each with their own advantages and disadvantages. Though S2-alar-iliac (S2AI) have demonstrated promising advantages over alternatives, the complex anatomy of the spinopelvic region demands precise insertion of the screws to create a biomechanically robust construct safely...

Objective This video is a step-by-step illustration of the laparoscopic-assisted mobilisation and resection of a sacrococcygeal teratoma Altman type III. Indication Laparoscopic supralevatory tumour mobilisation is an established method in selected centres and can be the initial step in approaching sacrococcygeal teratomas with an intrapelvic portion, facilitating a complete (R0) resection. Method Laparoscopic surgery is performed in supine position with a 5 mm umbilical trocar, a 5 mm trocar in the right upper abdomen, and two 3 mm trocars in the left middle and lower abdomen...

BACKGROUND: Primary tumors in the presacral (retrorectal) space are extremely rare in adults, with an estimated incidence of 0.0025 to 0.014 in large referral centers. Congenital varieties are most common and comprise two thirds of these tumors. Primary retroperitoneal sarcomas in the pelvic region are extremely rare. We report the ultrasound and the corresponding Computed Tomography (CT) features of a rare presacral fibrosarcoma in an adult woman, in whom the diagnosis was confirmed by a CT-guided biopsy...

Chordomas are rare tumours of the bone arising along the spine from clivus to sacrum. We compared three chordoma cell lines of the clivus region including the newly established clivus chordoma cell line, U-CH14, with nine chordoma cell lines originating from sacral primaries by morphology, on genomic and expression levels and with patient samples from our chordoma tissue bank. Clinically, chordomas of the clivus were generally smaller in size at presentation and patients with sacral chordomas had more metastases and more often recurrent disease...

Giant cell tumour of bone (GCTB) is an intermediate locally aggressive primary bone tumour, occurring mostly at the meta-epiphysis of long bones. Overexpression of receptor activator of nuclear factor kappa-B ligand (RANKL) by mononuclear neoplastic stromal cells promotes recruitment of numerous reactive multinucleated osteoclast-like giant cells, causing lacunar bone resorption. Preferential treatment is curettage with local adjuvants such as phenol, alcohol or liquid nitrogen. The remaining cavity may be filled with bone graft or polymethylmethacrylate (PMMA) bone cement; benefits of the latter are a lower risk of recurrence, possibility of direct weight bearing and early radiographic detection of recurrences...

High-intensity focused ultrasound describes the use of high-intensity focused ultrasound (HIFU) to ablate tumours without requiring an incision or other invasive procedure. This technique has been trialled on a range of tumours including uterine fibroids, prostate, liver and renal cancer. We describe our experience of using HIFU to ablate sacral chordoma in four patients with advanced tumours. Patients were treated under general anaesthetic or sedation using an ultrasound-guided HIFU device. HIFU therapy was associated with a reduction in tumour volume over time in three patients for whom follow up scans were available...

OBJECTIVE: Aneurysmal Bone Cyst (ABC) is a cystic lesion of bone, occurring in 70% of cases as a primary lesion. Even if the metaphyseal region of long bones is more frequently involved, vertebral localization is not rare: ABC represents 15% of all primary spine and sacral tumours. Selective arterial embolization (SAE) represents the first treatment option for vertebral ABC. However, in few cases, multiple SAEs are not possible. The aim of this work is to report two cases of vertebral ABC unresponsive to SAE positively treated with Denosumab...

Hibernoma is a benign adipose tumour that contains foetal brown fat cells. We report a case of hibernoma arising in the left ischium of a 65-year-old female with a past history of ovarian carcinoma. The patient presented with a relatively short history of left sacral/hip pain. Radiologically, the lesion, which was large (5 cm) and sclerotic, had been stable for a number of years. Histologically, it was composed mainly of plump cells with foamy, multivacuolated cytoplasm. These cells showed no reaction for epithelial, melanoma or leucocyte markers but expressed FABP4/aP2 and S100, indicating that they were brown fat cells...

INTRODUCTION: Peripheral nerve tumours are rarely acknowledged as a cause of radiating pain in lower limbs and suspicion is almost always pointed towards lumbo-sacral causes. Schwannomas are tumours of peripheral nerve sheaths occurring anywhere along the peripheral nervous system. Often it can produce symptoms, which can be misleading in cases where obvious swelling is not present. The diagnosis may therefore be delayed by several years of emergence of symptoms. Very few such cases have been reported previously and none of them had an intrasubstance location of the tumour as in our case...

We present the case of a 68-year-old woman who developed a painful subcutaneous tumour in the sacral region. Histological examinations revealed a characteristic zonal pattern with a central zone of liquefactive necrosis, surrounded by proliferated atypical fibroblasts and prominent vessels, indicating ischaemic fasciitis. We demonstrate that the characteristic features of ischaemic fasciitis revealed by ultrasonography are strongly associated with those revealed by pathological findings. We thus believe that ultrasonography is a valid tool for making an accurate diagnosis of ischaemic fasciitis...

AIMS: Osteosarcoma of the pelvis is a particularly difficult tumour to treat as it often presents late, may be of considerable size and/or associated with metastases when it presents, and is frequently chondroid in origin and resistant to chemotherapy. The aim of this study was to review our experience of managing this group of patients and to identify features predictive of a poor outcome. PATIENTS AND METHODS: Between 1983 and 2014, 121 patients, (74 females and 47 males) were treated at a single hospital: 74 (61...

Schwannomas are common, benign, slow growing tumours of peripheral nerve sheath arising from the schwann cells of the neuroectoderm. They do not transverse the nerve but remain within the sheath on top of the nerve. They rarely present in the sciatic nerve. Sciatic schwannomas may mimic symptoms of herniated disc, usually with radiation of pain to buttocks and thigh region with inability to walk for long distances and sometimes may present with claudication. In the absence of low back pain and with a normal Lumbo-Sacral MRI study, causes intrinsic to sciatic nerve needs to be thought off, which often delays the diagnosis...

PURPOSE: The sacrum is a rare but unfavourable location for Aneurysmal Bone Cysts (ABCs), surgical procedures aiming to achieve local tumour control can be mutilating. Aim of this study was to evaluate whether selective arterial embolisation (AE) of ABC of the sacrum is an effective treatment and might be an alternative to surgical treatment options. MATERIALS AND METHODS: Between 2007 and 2011 six patients (mean age 13.7 years, range 8 - 18 years) with an ABC of the sacrum were treated by AE...

INTRODUCTION: Sacral chordoma is a rare low-to-intermediate grade malignant tumour. The mainstay of treatment is still surgery with en bloc and wide resection margins, which can grant the best chances of a long-term control or cure of this disease. The first aim of this paper is to collect data about survival, time to local recurrence and metastasis among patients affected by sacral chordoma and primarily treated with surgery. The second aim is to analyze the influence of level resection, tumor volume and surgical margins on local recurrence...

REVIEW

Cauda equina syndrome refers to dysfunction of the cauda equina, the collection of ventral and dorsal lumbar, sacral and coccygeal nerve roots that surround the filum terminale. This most commonly occurs as a result of compression by a herniated lumbosacral disc. However, the syndrome may also complicate metastatic cancer or a primary neoplasm within or infiltrating the spinal canal. An accurate and timely diagnosis is critical to avoid irreversible loss of neurological function. The clinician and radiologist must therefore be aware of the many possible causes to guide timely management...

PURPOSE: Our aim was to introduce a novel combined hemipelvic endoprosthesis for pelvic reconstruction after Enneking type I/II/IV resection and to evaluate the biomechanical properties of the endoprosthesis using finite element analysis. METHODS: A three-dimensional finite element model of the postoperative pelvis was developed based on computed tomography (CT) images of the patient with the best post-operative limb function. A force of 400 N was applied along the longitudinal axis of the normal and post-operative pelvis for two positions: standing on two feet and sitting...
