Extraosseous Ewing’S Sarcoma

AbstractExtraosseous Ewing’s sarcoma (EES), first described in 1969, is a malignant mesenchymal tumor just like its intraosseous counterpart. Although Ewing’s sarcomas are common bone tumors in young children, EESs are rarer and more commonly found in older children/adults, often carrying a poorer prognosis. We discuss the multimodality imaging features of EES and the differential diagnosis of an aggressive appearing mass in proximity to skeletal structures, with pathologic correlates. This review highlights the need to recognize the variability of radiologic findings in EES such as the presence of hemorrhage, rich vascularity, and cystic or necrotic regions and its imaging similarity to other neoplasms that are closely related pathologically.

The authors report the case of a 58-year-old man presenting with a 3-year history of clinical signs of progressive cervical spondylotic myelopathy (CSM). Magnetic resonance imaging showed a severe stenosis of the cervical spinal canal at C3–4 and C5–6 levels due to multiple discopathies. High signal intensities on T2-weighted MR images of the spinal cord and low signal intensities on T1-weighted images at the C2–6 levels were noted, as was contrast enhancement at the C3–4 level. The patient underwent a bilateral decompressive laminectomy at C3–6. The patient did not show any clinical improvement. Thus, further cervical MR imaging was performed and the differential diagnosis of an intramedullary tumor was considered in view of the persisting intramedullary enhancement. This diagnosis prompted a second operation involving a posterior midline myelotomy and excision of an intramedullary ependymoma at the C3–4 level. Intramedullary tumors should be considered in the differential diagnosis of CSM with an atypical pattern of MR imaging features.

Spindle cell lipoma (SCL) is a rare neoplasm occurring predominantly in male patients between the ages of 45 and 70 years. We present a case of SCL arising in the sternomastoid muscle of a 46 year old male patient, which was completely excised at surgery. (Only 4 cases of SCL have been described within skeletal muscle and SCL has not previously been reported within sternomastoid.) The histological and magnetic resonance (MR) imaging features of this lesion are described and the differential diagnosis is discussed, with particular reference to its potential confusion with liposarcoma.

There is an extensive differential diagnosis for lesions of the external auditory canal, including congenital, benign, locally aggressive, and malignant processes. Although external auditory canal lesions are commonly identified clinically, imaging is helpful to determine if the process is isolated to the external auditory canal or to evaluate the extent of involvement of adjacent structures. Because staging of external auditory canal malignancy is based on the location and extent of tumor rather than the cell type, multimodality imaging is often necessary for surgical planning. This article reviews defining clinical and imaging features of external auditory canal lesions, presents an organized approach to their characterization on CT and MR imaging, and discusses their surgical implications.Learning Objective: To review the differential diagnosis of external auditory canal lesions and recognize their key imaging and clinical features, including surgical implications.
