Metastasis of breast cancer is often detected through a long-term course and difficult to diagnose. We report a case of brachial plexopathy suspected to be the initial lesion of breast cancer metastasis, which was only detected by magnetic resonance (MR) neurography. A 61-year-old woman was admitted to our hospital within 2 years after operation for breast cancer because of progressive dysesthesia and motor weakness initially in the upper limb on the affected side and subsequently on the contralateral side...

BACKGROUND: Neurologic lesions are relatively common after total shoulder arthroplasty. These injuries are mostly due to traction. We aimed to identify the arm manipulations and steps during reverse total shoulder arthroplasty (RTSA) that affect nerve stress. METHODS: Stress was measured in 10 shoulders of 5 cadavers by use of a tensiometer on each nerve from the brachial plexus, with shoulders in different arm positions and during different surgical steps of RTSA...

OBJECTIVE: This study assessed the neurotropism of bovine ephemeral fever (BEF) virus (BEFV) and described histomorphological abnormalities of the brain, spinal cord and peripheral nerves that may causally contribute to paresis or paralysis in BEF. METHODS: Four paralysed and six asymptomatic but virus-infected cattle were monitored, and blood and serum samples screened by qRT-PCR, virus isolation and neutralisation tests. Fresh brain, spinal cord, peripheral nerve and other tissues were qRT-PCR-tested for viral RNA, while formalin-fixed specimens were processed routinely and immunohistochemically evaluated for histomorphological abnormalities and viral antigen distribution, respectively...

This study aims at the effects of traumatic brachial plexus lesion with root avulsions (BPA) upon the organization of the primary motor cortex (M1). Nine right-handed patients with a right BPA in whom an intercostal to musculocutaneous (ICN-MC) nerve transfer was performed had post-operative resting state fMRI scanning. The analysis of empirical functional correlations between neighboring voxels revealed faster correlation decay as a function of distance in the M1 region corresponding to the arm in BPA patients as compared to the control group...

We discuss the case of an independent 80-year-old Caucasian woman, being treated with new oral anticoagulants for a previous deep vein thrombosis, who had fallen on her right shoulder. She made a delayed presentation to the emergency department with a wrist drop in her right dominant hand. She had right arm bruising with good distal pulses but had a global neurological deficit in the hand. Plain radiographs of the shoulder, humerus, elbow, forearm and wrist demonstrated no fractures. MRI showed a significant right axillary lesion distorting the surrounding soft tissues, including the brachial plexus, and CT with contrast confirmed this to be a large axillary pseudoaneurysm...

Brachial plexus lesion results in loss of motor and sensory function, being more harmful in the neonate. Therefore, this study evaluated neuroprotection and regeneration after neonatal peripheral nerve coaptation with fibrin sealant. Thus, P2 neonatal Lewis rats were divided into three groups: AX: sciatic nerve axotomy (SNA) without treatment; AX+FS: SNA followed by end-to-end coaptation with fibrin sealant derived from snake venom; AX+CFS: SNA followed by end-to-end coaptation with commercial fibrin sealant...

Primary cutaneous gamma-delta T-cell lymphoma (PCGD-TCL) is a clonal proliferation of gamma-delta T cells with a cytotoxic phenotype that is typically characterized by an aggressive clinical course with ulcerative plaques or subcutaneous nodules. In this report, the authors describe a patient who developed an ulcerated tumor on the left upper extremity and painful papules and nodules on the right lower extremity. Interestingly, several of the papulonodules on the right lower extremity underwent spontaneous involution...

BACKGROUND: For the reconstruction of brachial plexus lesions, restoration of elbow flexion and shoulder function is fundamental and is achieved by dual nerve transfers. Shoulder stabilization and movement are crucial in freedom of motion of the upper extremity. In patients with C5-C6 brachial plexus injury, spinal accessory nerve transfer to the suprascapular nerve and a fascicle of ulnar nerve to musculocutaneous nerve (dual nerve transfer) are carried out for restoration of shoulder abduction and elbow flexion, respectively...

INTRODUCTION: We investigated interrater reliability of overall assessment of nerve root lesions by electrodiagnostic testing (EDX) in neonatal brachial plexus palsy (NBPP). METHODS: Two blinded, board-certified reviewers retrospectively reviewed de-identified EDX data from 37 infants with NBPP for 2005-2012. Only nerve conduction and electromyography needle data were included. The examiners independently assigned 1 of 4 nerve root lesion categories: 1) normal, pre-ganglionic lesion (avulsion), 2) post-ganglionic lesion (rupture), 3) normal, or 4) "unable to determine...

The etiologies of Bell's palsy and brachial neuritis remain uncertain, and the conditions rarely co-occur or reoccur. Here we present a woman in her twenties who had several relapsing-remitting episodes with left-sided facial palsy and brachial neuropathy. The episodes always started with painful left-sided oral blisters. Repeat PCRs HSV-1 DNA from oral vesicular lesions were positive. Extensive screening did not reveal any other underlying cause. Findings on MRI T2-weighted brachial plexus STIR images, using a 3...

A 9-year-old male mixed breed cat showed chronic progressive neurological symptoms, which are represented by ataxia and seizures. At necropsy, spinal roots and spinal ganglions at the level of sixth cervical nerve to second thoracic nerve were bilaterally swollen and replaced by white mass lesions. Right brachial plexus and cranial nerves (III, V and VII) were also swollen. A mass lesion was found in the right frontal lobe of the cerebrum. Histologically, neoplastic lymphocytes extensively involved the peripheral nerves, and they infiltrated into the cerebral and spinal parenchyma according to the peripheral nerve tract...

INTRODUCTION: Brachial plexus (BP) tumors are very rare tumors, with less than 800 cases been described in the literature worldwide since 1970. These tumors often present as local or radicular pain, with scant or no neurological deficits. These symptoms are shared by many other more common rheumatologic diseases, thus making their diagnosis difficult in most cases. Additionally, these tumors often present as lumps and are therefore biopsied, which carries a significant risk of iatrogenic nerve injury...

BACKGROUND: Malignant peripheral nerve sheath tumors (MPNSTs) of the brachial plexus have unique radiographic and clinical findings. Patients often present with progressive upper extremity paresthesias, weakness, and pain. On magnetic resonance (MR) imaging, lesions are isointense on T1-weighted and hyperintense on T2-weighted sequences, while also demonstrating marked enhancement on MR studies with gadolinium diethylenetriamine pentaacetic acid. On the basis of their characteristic MR imaging features and rapid clinical progression, two brachial plexus lesions proved to be organizing hematomas rather than MPNST...

Background The lateral branch of the thoracodorsal nerve (LBTN) is used for nerve transfer in facial, musculocutaneous, axillary nerve injuries and for irreparable C5, C6 spinal nerve lesions and accessory nerve defects. For a successful surgical outcome, the nerve to be used in nerve transfer should be of adequate length and thickness for nerve coaptation. Aim Our objective was to evaluate the length of the LBTN that could be obtained as a donor nerve, externally and within the muscle. Method Eight (8) cadavers with intact upper limbs and thorax which could be positioned in the anatomical position were selected for the study...

BACKGROUND: The traditional surgical approach to repair of brachial plexus lesions involves use of whole segment ulnar nerve graft for contralateral seventh cervical (cC7) nerve root transfer, which sabotages the possibility of ulnar nerve recovery. We assessed the anatomical feasibility of a new approach that involves preservation of the motor branch of ulnar nerve (MBUN), for a later stage repair using the recovered pronator quadratus motor branch (PQMB), subsequent to the cC7 transfer procedure...

BACKGROUND The aim of the present study was to evaluate the donor nerve from the C7 spinal nerve of the rabbit brachial plexus after a coaptation procedure. Assessment was performed of avulsion of the C5 and C6 spinal nerves treated by coaptation of these nerves to the C7 spinal nerve. MATERIAL AND METHODS After nerve injury, fourteen rabbits were treated by end-to-side coaptation (ETS), and fourteen animals were treated by side-to-side coaptation (STS) on the right brachial plexus. Electrophysiological and histomorphometric analyses and the skin pinch test were used to evaluate the outcomes...

Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT) is the most common subtype of marginal zone lymphoma (MZL), with stomach being the most frequent primary site, followed by salivary gland, lung and ocular adnexa. Although clinically indolent, MALT lymphoma has the potential of local recurrence and systemic spread. Amyloid deposition is a very unusual complication of MALT lymphoma. In this study, we report clinicopathologic features of 5 cases of MALT lymphomas with associated amyloid deposits...
