Benign and malignant tumor of the uterine body with broccoli sign: MR imaging features for differential diagnosis

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.

Male Patients

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.

Introduction: Ischial lesion is considered rare. Aim: In this study, we review the patient demographics, imaging appearances, and pathological entities which arise in the ischium with the aim of facilitating a differential diagnosis. This allows appropriate management to be instigated in a timely fashion, enabling lesion to be stratified into those that can be managed locally or referred to a specialist center. Materials and Methods: A retrospective search of our oncology and radiology database was performed to identify primary ischial lesions. Results: The search revealed 82 cases with primary involvement of ischium. The most common benign tumor was aneurysmal bone cyst in patients under 40 years and osteochondroma in patients over the age of 40 years. Metastasis was the most common malignant tumor in both cohorts (<40 years and over 40 years). Conclusion: We present the patient demographics, imaging appearances of pathological entities which arise in the ischium with the aim of facilitating a differential diagnosis.

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.
