: Differentiation of malignant from benign soft tissue tumors is challenging with imaging alone, including that by magnetic resonance imaging and computed tomography. However, the accuracy of this differentiation has increased owing to the development of novel imaging technology. Detailed patient history and physical examination remain essential for differentiation between benign and malignant soft tissue tumors. Moreover, measurement only of tumor size based on Response Evaluation Criteria In Solid Tumors criteria is insufficient for the evaluation of response to chemotherapy or radiotherapy. Change in metabolic activity measured by 18F-fluorodeoxyglucose positron emission tomography or dynamic contrast enhanced-derived quantitative endpoints can more accurately evaluate treatment response compared to change in tumor size. Magnetic resonance imaging can accurately evaluate essential factors in surgical planning such as vascular or bone invasion and “tail sign”. Thus, imaging plays a critical role in the diagnosis and treatment of soft tissue tumors.

Medical imaging plays a pivotal role in the detection, diagnosis, and clinical management of primary soft tissue tumors. Various imaging modalities have been used, and each modality offers unique advantages in the workup of soft tissue tumors by localizing the lesions in different compartments of the body and characterizing macroscopic tissue composition of the lesions in a noninvasive and safe manner. We review the clinical role and technical aspects of the frequently used imaging modalities, including magnetic resonance imaging (MRI), computed tomography, ultrasonography, positron emission tomography, and plain radiography with an emphasis on MRI as a mainstay imaging modality and a brief discussion of advanced techniques. We also review imaging features of common soft tissue tumors that can be detected and characterized using current imaging techniques. This review contains 54 figures, 1 table and 37 references.   Key words: computed tomography, diffusion-weighted imaging, imaging, magnetic resonance imaging, positron emission tomography, soft tissue, technique, tumor, ultrasonography

Mri Characteristics

Schwannomas are benign soft-tissue tumors that arise from peripheral nerve sheaths throughout the body and are commonly encountered in patients with neurofibromatosis Type 2. The vast majority of schwannomas are benign, with rare cases of malignant transformation reported. In this pictorial review, we discuss the magnetic resonance imaging (MRI) appearance of schwannomas by demonstrating a collection of tumors from different parts of the body that exhibit similar MRI characteristics. We review strategies to distinguish schwannomas from malignant soft-tissue tumors while exploring the anatomic and histologic origins of these tumors to discuss how this correlates with their imaging findings. Familiarity with the MRI appearance of schwannomas can help aid in the differential diagnosis of soft-tissue masses, especially in unexpected locations.

Neural Origin

AbstractNerve tumors are rare and heterogeneous soft tissue tumors arising from a peripheral nerve or showing nerve sheath differentiation. In a radiologic setting it is necessary to recognize soft tissue lesions that are of neural origin, their association with a peripheral nerve, and whether they are a true tumor or a so-called pseudotumor such as a neuroma, fibrolipoma, or peripheral nerve sheath ganglion. Ultrasound (US) and magnetic resonance imaging are the best modalities to characterize these lesions. US can be used to guide biopsy in difficult and uncertain cases when the lesion is either indeterminate or possibly malignant. At present, no single imaging feature or reproducible criteria, or a combination, can differentiate reliably between a neurofibroma and a schwannoma or discriminate with certainty between benign and malignant neurogenic tumors. Adequate imaging and consultation with a nerve tumors/sarcoma unit is advised.
