Nerve Tumour

Fourteen cases of peripheral nerve tumour which had been examined by MRI were reviewed. T1-weighted images showed the tumours to be of intermediate signal and T2-weighted images showed a high signal with some heterogeneity. These appearances are not specific to peripheral nerve tumours, although the diagnosis may be suggested if the lesion arises from a major nerve trunk. The association with a nerve trunk may be defined by MRI, thus assisting with surgical planning. Neurilemmomas, neurofibromas and malignant nerve sheath tumours could not be differentiated with certainty using MR alone. The MR features of lipofibromatous hamartoma are reported.

Peripheral Nerve Tumours

This chapter on peripheral nerve sheath tumours (PNSTs) explores the pathology, clinical presentation, investigation, management, and outcomes of both benign and malignant peripheral nerve sheath tumours (MPNSTs). The focus is centred upon the more commonly encountered tumours: schwannoma, neurofibroma, and perineurioma. Significant emphasis is also given to the rarer but life-threatening MPNSTs. It aims to equip the reader with the latest information available in the literature with regards to PNSTs occurring sporadically or in association with inherited conditions. Up to date investigation and management options available are also presented. With the detailed insights provided, the aim is to ensure that the reader would be confident in managing patients presenting with peripheral nerve tumours.

Knee Magnetic Resonance Imaging

AbstractHoffa's fat pad can be affected by a variety of tumors. Schwannomas are benign and typically solitary neoplasms of the peripheral nerve sheath; they are made up of the neoplastic Schwann cells and are usually located eccentrically. Malignant schwannomas are extremely uncommon. Here we report a case of an intra-articular schwannoma of the knee. A 54-year-old man presented with a painful lump in the medial aspect of the knee. Magnetic resonance imaging revealed a well-circumscribed intra-articular mass, which was later diagnosed as an intra-articular schwannoma based on biopsy findings.

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.

Malignant peripheral nerve sheath tumor (MPNST) involving bone is rare. We report a case of MPNST of the fifth toe. The lesion was located in the distal phalanx of the right fifth toe and extended into surrounding subcutaneous tissues. Findings on magnetic resonance imaging and histological features of the case are described and the literature is briefly reviewed.
