Abstract
A middle-aged woman presented with hypertensive emergency after corticosteroid treatment for Sjögren syndrome-associated multiple mononeuropathy with suspected systemic sclerosis. Hypertensive heart failure with hyperreninemia improved with antihypertensives, including aliskiren; however, she became hemodialysis-dependent. Clinical findings and biopsy-proven thrombotic microangiopathy indicated conditions resembling scleroderma renal crisis (SRC). Severe hypertension and heart failure with hyperreninemia occurred after stopping aliskiren for hypotension due to diverticular bleeding, which improved after the reintroduction of aliskiren. Aliskiren appears to be effective in managing hypertensive heart failure in patients with SRC. Nevertheless, hemodialysis remained necessary in our case, and whether or not aliskiren can restore the renal function is unclear.

Abstract
The extent of nerve involvement in leprosy is highly variable in distribution and clinical presentation. Mononeuropathies, multiple mononeuropathies, and polyneuropathies can present both in the context of a cutaneous and/or systemic picture and in the form of pure neuritic leprosy (PNL). The differential diagnosis of leprosy neuropathy remains challenging because it is a very rare condition and, especially in Western countries, is often overlooked. We report one case of the polyneuropathic form of PNL (P-PNL) and one case of multiple mononeuropathy in paucibacillary leprosy. In both cases, the diagnosis was achieved by performing a sural nerve biopsy, which showed subverted structure, severe infiltration of inflammatory cells in nerve fascicles, granulomatous abnormalities, and the presence of alcohol-acid-resistant, Ziehl-Neelsen-positive bacilli inside the nerve bundles. Leprosy remains an endemic disease in many areas of the world, and globalization has led to the spread of cases in previously disease-free countries. In this perspective, our report emphasizes that the diagnostic possibility of leprosy neuropathy should always be taken into account, even in Western countries, in the differential diagnostic process of an acquired sensory polyneuropathy or multineuropathy and confirms that nerve biopsy remains a useful procedure in working up neuropathies with unknown etiology.

Abstract
A 72-year-old male complained of fever lasting 1 month and developed muscle weakness and paresthesia in the legs. He presented with muscle weakness, grasping pain, decreased deep tendon reflexes in the extremities, and reduction of tactile sensation in the distal parts of the left leg muscles. Blood tests revealed leukocytosis and inflammatory reactions. Collagen-disease-specific autoantibodies including anti-double-stranded DNA and anti-Scl-70 antibodies were positive, but antineutrophil cytoplastic antibodies were negative. Nerve conduction studies revealed asymmetric axonal degeneration, indicating multiple mononeuropathy. We started intravenous methylprednisolone pulse and plasma exchange therapies. However, the patient developed intestinal necrosis and perforation, and he died 44 days after the onset of fever. An autopsy revealed vasculitis in small- to medium-sized vessels in multiple organs as well as myoglobin casts in the renal tubules, which were suggestive polyarteritis nodosa (PAN) accompanied with rhabdomyolysis. Positivity for collagen-disease-specific autoantibodies and accompanying rhabdomyolysis are atypical findings with PAN. This patient was not clinically diagnosed as PAN, and so promptly starting immunotherapies should be considered when a case presents with evidence of vasculitis.

Abstract
The neurologic symptoms that appear due to paraneoplastic syndrome may give manifestations of undiagnosed tumor, and give an opportunity for early detection and treatment of it. Case Presentation Here the authors present a case of a 54-year-old woman who suffered from rapidly progressive muscle weakness, accompanied by right third cranial nerve palsy. Clinical Discussion The nerve conduction study consistent with multiple mononeuropathy, and laboratories revealed undiagnosed diabetes mellitus but elevated erythrocyte sedimentation rate and the rapid progression prompted for additional investigations. Brain MRI, repetitive nerve stimulation, lumbar puncture, and paraneoplastic panel were all negative. Computed tomography scan with contrast for the abdomen showed a right renal mass consistent with renal cell carcinoma. The tumor was removed and steroids and intravenous immunoglobulin was started but without any clinical improvement because of the late presentation. Conclusion Patients with renal cell carcinoma can present with paraneoplastic syndromes but multiple mononeuropathy are extremely rare. It is crucial to investigate for all possible causes of neuropathy and not attributing it to a new discovered diabetes in the presence of clinical and laboratory red flags such as rapid progression and elevated erythrocyte sedimentation rate.

Abstract
Introduction Hansen's disease (HD) primarily infects peripheral nerves, with patients without HD being free of peripheral nerve damage. Household contacts (HHCs) of patients with HD are at a 5-10 times higher risk of HD than the general population. Neural thickening is one of the three cardinal signs that define a case of HD according to WHO guidelines, exclusively considering palpation examination that is subjective and may not detect the condition in the earliest cases even when performed by well-trained professionals. High-resolution ultrasound (HRUS) can evaluate most peripheral nerves, a validated technique with good reproducibility allowing detailed and accurate examination. Objective This study aimed to use the peripheral nerve HRUS test according to the HD protocol as a diagnostic method for neuropathy comparing HHCs with healthy volunteers (HVs) and patients with HD. Methods In municipalities from 14 different areas of Brazil we selected at random 83 HHC of MB-patients to be submitted to peripheral nerve ultrasound and compared to 49 HVs and 176 HD-patients. Results Household contacts assessed by HRUS showed higher median and mean absolute peripheral nerve cross-sectional area (CSA) values and greater asymmetries (ΔCSA) compared to HVs at the same points. Median and mean absolute peripheral nerve CSA values were higher in patients with HD compared to HCCs at almost all points, while ΔCSA values were equal at all points. Mean ± SD focality (ΔTpT) values for HHCs and patients with HD, respectively, were 2.7 ± 2.2/2.6 ± 2.2 for the median nerve, 2.9 ± 2.7/3.3 ± 2.9 for the common fibular nerve (p > 0.05), and 1.3 ± 1.3/2.2 ± 3.9 for the ulnar nerve (p < 0.0001). Discussion Considering HRUS findings for HHCs, asymmetric multiple mononeuropathy signs (thickening or asymmetry) in at least 20% of the nerves evaluated could already indicates evidence of HD neuropathy. Thus, if more nerve points are assessed in HHCs (14 instead of 10), the contacts become more like patients with HD according to nerve thickening determined by HRUS, which should be a cutting-edge tool for an early diagnosis of leprosy cases.

Abstract
A sacral dural arteriovenous fistula (dAVF) is extremely rare, and the pathophysiological and clinical features have not been established. A 70-year-old man developed gradually progressive right-dominant bilateral sensory disorder of the lower limbs. His clinical course and electrophysiological findings were similar to those of multiple mononeuropathy. However, angiography showed a sacral dAVF at the right intervertebral foramen between the fifth lumbar and first sacral vertebrae. Endovascular embolization of the dAVF improved his clinical symptoms and electrophysiological findings. A sacral dAVF can mimic multiple mononeuropathy in terms of its clinical features and electrophysiological findings. A sacral dAVF is a treatable disease and should be considered as a differential diagnosis of lower extremity disorders.

Abstract
BACKGROUND Multiple mononeuropathy is a rare presentation of primary (AL) amyloidosis and nerve biopsy is usually needed for diagnosis. Conventional imaging is useful to identify proximal nerve involvement but may be inadequate. We report a patient with multiple mononeuropathy whose presentation was suggestive of AL amyloid neuropathy and in whom repeated tissue biopsies were negative for amyloid (including two sensory nerves and one muscle). METHODS The patient underwent magnetic resonance imaging (MRI) and whole body 18 F-florbetapir positron emission tomography (PET)/MRI. RESULTS Whole body 18 F-florbetapir PET/MRI revealed abnormal low-level florbetapir uptake in the right proximal tibial and peroneal nerves, which provided a target for a sciatic bifurcation fascicular nerve biopsy that was diagnostic of AL amyloidosis. CONCLUSIONS 18 F-florbetapir PET/MRI imaging is a promising diagnostic tool for patients with suspected peripheral nerve amyloidosis (including multiple mononeuropathy) in whom conventional imaging and nerve and muscle biopsies miss the pathology.

Abstract
Multiple mononeuropathy is an unusual form of peripheral neuropathy involving two or more nerve trunks. It is a syndrome with many different causes. We reviewed the clinical, electrophysiological and nerve biopsy findings of 14 patients who suffered from multiple mononeuropathy in our clinic between January 2009 and June 2013. Patients were diagnosed with vasculitic neuropathy (n = 6), perineuritis (n = 2), chronic inflammatory demyelinating polyradiculoneuropathy (n = 2) or Lewis-Sumner syndrome (n = 1) on the basis of clinical features, laboratory data, electrophysiological investigations and nerve biopsies. Two patients who were clinically diagnosed with vasculitic neuropathy and one patient who was clinically diagnosed with chronic inflammatory demyelinating polyradiculoneuropathy were not confirmed by nerve biopsy. Nerve biopsies confirmed clinical diagnosis in 78.6% of the patients (11/14). Nerve biopsy pathological diagnosis is crucial to the etiological diagnosis of multiple mononeuropathy.
