11/49. Intraneural nerve metastasis with multiple mononeuropathies.Although cancer is a frequent condition, neoplastic involvement of the peripheral nervous system is rare. The mechanisms are heterogeneous and include lesions within the cerebrospinal fluid (CSF) space, local invasion (e.g. brachial plexus), compression, rarely direct infiltration, perineurial spread and even rarer intranerval metastasis. A 47-year-old woman had been treated for a carcinoid 10 years earlier and had received axillar irradiation. At presentation she suffered from weakness of the biceps brachii and was experiencing pain radiating from the axilla into the forearm and thumb. MR scans of the brachial plexus were negative and her symptoms were primarily considered to stem from a postradiation brachial plexopathy, Because of increasing pain, the brachial plexus was explored and a metastasis in the left musculocutaneous nerve was resected. Several months later, numbness and pain appeared in the ulnar nerve and another intrafascicular metastasis in the ulnar nerve was discovered. Resection with preservation of remaining fascicles was performed. This rare case report demonstrates that multiple mononeuropathies, resembling multiplex neuropathy, may be caused by intranerval metastasis.- - - - - - - - - - ranking = 1keywords = nerve (Clic here for more details about this article) |
12/49. Compressive neuropathy of the brachial plexus and long thoracic nerve: a rare complication of heparin anticoagulation.We present a case of a 69-year-old woman who developed brachial plexopathy and long thoracic nerve palsy secondary to compression from a hematoma while receiving heparin therapy for the treatment of a stroke. The patient was treated conservatively with discontinuation of heparin and had complete resolution of her compressive neuropathy. This is the first report of a patient with long thoracic nerve palsy with a brachial plexopathy complicating anticoagulation. We review the literature on hematoma-induced compressive neuropathies and treatment options. Our review concludes by emphasizing the importance of clinical judgment in determining the best therapeutic modality.- - - - - - - - - - ranking = 0.85714285714286keywords = nerve (Clic here for more details about this article) |
13/49. A brachial plexopathy due to myositis ossificans. Case report and review of the literature.myositis ossificans (MO) is a disorder characterized by the intramuscular proliferation of fibroblasts and osteoblasts, with subsequent deposition of bone and cartilage. A typical clinical presentation involves traumatic injury to a young adult, usually localized to the thigh, buttock, or upper arm, with resultant MO and mildly restricted range of motion in adjacent joints. Rarely, MO is associated with peripheral neuropathies involving the radial, median, sciatic, and sural nerves. The authors present an unusual case of MO causing a brachial plexopathy. To their knowledge, this is the first description of such a presentation.- - - - - - - - - - ranking = 0.14285714285714keywords = nerve (Clic here for more details about this article) |
14/49. Isolated brachialis wasting: an unusual presentation of neuralgic amyotrophy.Although neuralgic amyotrophy can selectively affect discrete components of the brachial plexus including individual peripheral nerves, involvement of an individual nerve fascicle is rare. Discrete fascicular musculocutaneous neuropathy as a manifestation of neuralgic amyotrophy has not previously been reported to our knowledge. We report two cases of otherwise typical neuralgic amyotrophy with isolated brachialis muscle wasting. Abnormal spontaneous activity, motor unit remodeling, or both, was observed only in the brachialis muscle. Lateral antebrachial cutaneous nerve conduction studies were normal. These cases serve to broaden the spectrum of the clinical presentation of neuralgic amyotrophy.- - - - - - - - - - ranking = 0.42857142857143keywords = nerve (Clic here for more details about this article) |
15/49. Massive growth of a meningioma into the brachial plexus and thoracic cavity after intraspinal and supraclavicular resection. Case report and review of the literature.Extracranial meningiomas comprise approximately 2% of all meningiomas. Involvement of peripheral nerves by meningioma, either by a primary tumor or through secondary extension of an intraaxial lesion, is a much rarer entity; there have been only two reported primary brachial plexus meningiomas and one description of secondary involvement of the brachial plexus by extension of an intraaxial lesion. Although thoracic cavity meningiomas have been described in the literature, their pathogenesis is poorly understood. The authors present the case report of a 36-year-old man who was initially treated for a thoracic spinal meningioma that infiltrated the brachial plexus. After resection, progressive and massive growth with infiltration of the brachial plexus and pleural cavity occurred over a 5-year period despite radio- and chemotherapy. The case report is followed by a review of the literature of this rare entity.- - - - - - - - - - ranking = 0.14285714285714keywords = nerve (Clic here for more details about this article) |
16/49. A case of multiple schwannomas of the trigeminal nerves, acoustic nerves, lower cranial nerves, brachial plexuses and spinal canal: schwannomatosis or neurofibromatosis?In most cases, while schwannoma is sporadically manifested as a single benign neoplasm, the presence of multiple schwannomas in one patient is usually indicative of neurofibromatosis 2. However, several recent reports have suggested that schwannomatosis itself may also be a distinct clinical entity. This study examines an extremely rare case of probable schwannomatosis associated with intracranial, intraspinal and peripheral involvements. A 63-year-old woman presented with a seven-year history of palpable lumps on both sides of the supraclavicular area and hearing impairment in both ears. On physical examination, no skin manifestations were evident. Facial sensory change, deafness in the left ear and decreased gag reflex were revealed by neurological examination. magnetic resonance imaging revealed multiple lesions of the trigeminal nerves, acoustic nerves, lower cranial nerves, spinal accessory nerve, brachial plexuses, and spinal nerves. Pathological examination of tumors from the bilateral brachial plexuses, the spinal nerve in the T8 spinal position and the neck mass revealed benign schwannomas. Following is this patient case report of multiple schwannomas presenting with no skin manifestations of neurofibromatosis.- - - - - - - - - - ranking = 2.5715422657643keywords = nerve, neoplasm (Clic here for more details about this article) |
17/49. Acute rhabdomyolysis and brachial plexopathy following alcohol ingestion.An unusual case of brachial plexopathy following alcohol-induced rhabdomyolysis is presented. The patient's rhabdomyolysis developed during sleep after an acute alcohol binge and there was no history of muscle trauma. It is thought that the brachial plexopathy developed due to direct compression of the plexus from swollen muscles of the shoulder girdle. The lack of similar reported cases despite the common clinical scenario of prolonged unconsciousness following excess alcohol intake suggests that other factors may be important in the development of muscle and nerve damage in susceptible individuals.- - - - - - - - - - ranking = 0.14285714285714keywords = nerve (Clic here for more details about this article) |
18/49. A rare association between malignant mediastinal seminoma and other malignant neoplasms.Primary malignant mediastinal seminomas (PMMS) are rare tumors accounting for 1-6% of all mediastinal tumors. PMMS mostly affect young men, arising from primordial germ cells that abnormally migrate from the ectoderm of the yolk sac to the gonadal region. They are clinically and biologically distinct from primary testicular tumors and seem to have a worse prognosis. Due to the rarity of the disease, the choice of treatment is a matter of debate. literature data do not show any association between this kind of tumor and malignant Schwannoma or thyroid carcinoma. In this report we describe the case of a patient affected by PMMS and 12 yr later by a malignant brachial plexus Schwannoma and papillary thyroid carcinoma (PTC). Since both mediastinal seminoma and Schwannoma were treated with surgery followed by local radiotherapy, we were not able to ascertain if either PTC or Schwannoma had been induced by radiotherapy or represented a casual neoplastic association.- - - - - - - - - - ranking = 0.00045477734275139keywords = neoplasm (Clic here for more details about this article) |
19/49. Brachial plexopathy associated with systemic sclerosis.Neurological involvement is uncommon in systemic sclerosis. Most of the reported cases concern trigeminal neuropathy or peripheral nerve entrapment. We report a third case of brachial plexopathy, presumably related to vasculitis, in a patient with systemic sclerosis, which improved after cyclophosphamide therapy.- - - - - - - - - - ranking = 0.14285714285714keywords = nerve (Clic here for more details about this article) |
20/49. Bilateral elbow flexion reconstruction with functioning free muscle transfer for obstetric brachial plexus palsy.A child suffered a bilateral obstetric brachial plexus palsy involving the C5 and C6 nerve roots. Abduction of the shoulder joints had recovered by 1 year, but elbow flexion did not recover on either side. Free gracilis muscle transfers were performed on both sides, at an interval of 6 months, to achieve elbow flexion. The spinal accessory nerve was used as the donor nerve.- - - - - - - - - - ranking = 0.42857142857143keywords = nerve (Clic here for more details about this article) |
