Purpose: Ewing’s family tumour is an extremely rare tumour, with annual incidence rates amongst Caucasian children <21 years being in the range of 2–3 cases per million in the U.S. There are mainly three subtypes including Ewing’s sarcoma (ES) of bone, extraosseous (EO) Ewing’s tumour and Peripheral primitive neuroectodermal tumour. Although extremely rare, this study represents a review of various types of cases and the significance of imaging including its baseline and post-treatment response radiological characteristics. There are a very few cases of EO ES in the current literature with variable spectrum of tumour site and their imaging characteristics.Materials and Methods: Electronic records were retrospectively reviewed from 1 May 2011 to 1 May 2016 with patients who were diagnosed as histologically proven ES. A number of patients, gender and base line computed tomography (CT)/magnetic resonance imaging findings for staging were reviewed.Results: A total of 568 patients with diagnosed ES were analysed, of which 15 patients had EO type of ES. Of these only 8 patients had baseline imaging available which included tumours arising from the occipital region, orbit, anterior mediastinum, anterior abdominal wall, mesentery, kidney, prostate gland and presacral region.Conclusion: EO ES is a rare entity and can involve a wide array of soft tissue organs. A cross-sectional imaging with CT and MR has a key role in pre- and post-treatment assessment.Key words: Computed tomography, Ewing’s sarcoma, extraosseous Ewing’s, magnetic resonance imaging, peripheral primitive neuroectodermal tumour

Abstract OBJECTIVE Ewing's sarcoma is a malignant bone tumor occurring most frequently in the long bones and flat bones as a solitary lesion during the first 2 decades of life. Ewing's sarcoma and peripheral primitive neuroectodermal tumor have recently been considered to be the same entity because of histological and molecular similarities. CLINICAL PRESENTATION A 25-year-old man presented with swelling in the right parietal region. Magnetic resonance imaging scans showed 2 mixed intense mass lesions in the right parietal and left frontal areas with heterogeneous gadolinium enhancement. A computed tomographic scan revealed osteolytic changes of the inner calvarial bone. Ga-67 citrate scintigraphy demonstrated abnormal uptake in the right parietal and the left frontal areas consistent with the findings on magnetic resonance imaging scans. There was no uptake lesion beyond the cranium. The patient underwent surgical excision of the right parietal lesion. INTERVENTION Histological examinations showed densely packed, small round cells with rosette formation. The cells had scanty clear cytoplasm, and regular vesicular and hyperchromatic nuclei. Electron microscopy showed little differentiation to neuronal tissue, indicating Ewing's sarcoma. After surgical treatment, conventional whole cranial irradiation of 40 Gy and chemotherapy were conducted. The tumor in the left frontal region disappeared. Follow-up examinations showed no evidence of recurrence 1 year after the surgery. CONCLUSION Although quite rare, Ewing's sarcoma should be taken into consideration as a differential diagnosis of multiple cranial mass lesions in adulthood.

Extraskeletal Ewing’S Sarcoma

AbstractBackground:Extraskeletal Ewing's sarcoma is a rare tumour of mesenchymal origin, which is histologically similar to primary osseous Ewing's sarcoma. The majority of cases have been reported in the lower limb and paravertebral region, with a few cases reported in the neck.Methods:We report a patient with extraskeletal Ewing's sarcoma presenting with a right-sided neck mass, vocal fold palsy and T1 nerve root involvement. The detection of characteristic features on computed tomography and magnetic resonance imaging scans, in conjunction with histological analysis, was required to make the diagnosis.Results:Radiological imaging demonstrated that the tumour was infiltrating through the neural exit foramina of the lower cervical nerve roots, with encasement of the vertebral artery. The patient was managed with combination chemotherapy for systemic control and irradiation for local control.Conclusion:Extraskeletal Ewing's sarcoma has a propensity to occur in a paravertebral location, being found rarely in the cervical region, and has a predilection to infiltrate through neural exit formina. Computed tomography and magnetic resonance imaging are helpful in the diagnosis of this rare tumour.

Long Term Follow Up

Abstract OBJECTIVE AND IMPORTANCE: The Ewing's sarcoma (ES) family of tumors is a relatively rare entity, presenting most commonly in children. While the most common sites for this group of tumors are the trunk and the extremities, this case is unique in that we describe a long-term follow-up with an ES presenting in the cavernous sinus. CLINICAL PRESENTATION: We report the case of a 13-year-old girl presenting with the symptoms of classic orbital apex syndrome. Magnetic resonance imaging disclosed a cavernous sinus mass engulfing the optic nerve and extending into the superior orbital fissure. INTERVENTION: Evaluation of this patient included intracranial magnetic resonance imaging angiography and biopsy of the cavernous sinus mass lesion. Histopathological findings yielded a diagnosis of ES. Further work-up demonstrated that the patient's thyroid was also involved. The tumor was treated with radiation therapy to both sites and, subsequently, after confirmed metastases to other sites, 11 cycles of doxorubicin-based chemotherapy, as well as bone marrow transplantation. However, the patient succumbed to the illness 18 months after her initial diagnosis. CONCLUSION: The cavernous sinus is an unusual site for ES, but given the vascularity and the frequency of this tumor in childhood, the diagnosis should be entertained. This patient with an ES of cavernous sinus may be the first reported case with a long-term follow-up in the literature.

Ewing’s sarcoma is a malignant tumor, with an extremely aggressive growth pattern and a high risk of metastasis. In our work we demonstrated a case of primary lesion of Ewing’s sarcoma of the thoracic vertebra in a 10-year-old girl. Localization, in this situation, the tumor poses a serious threat to the development of neurological deficits, which is associated with a high need for early recognition of this neoplasia with the help of modern methods of radiation diagnosis (computed tomography and magnetic resonance imaging, SPECT).
