A 53 year old-female patient with lupus had undergone a cephalo-medullary nailing for a femur shaft fracture 30 years ago. This was complicated by osteomyelitis, requiring multiple debridement procedures and hardware removal. Recently, she developed a painful soft tissue mass in the same region, which was ultimately diagnosed as pyomyositis. Because of chronic bone changes due to her past history, traditional imaging could not differentiate between osteomyelitis infarction and pseudotumor. A combined indium-labeled leukocyte scan with a technetium-99 sulfur colloid marrow scan ruled out osteomyelitis and guided proper treatment without osseous debridement and thus prevented unnecessary cross-contamination of the bone...

BACKGROUND: Wernekink commissure syndrome causes a peculiar combination of internuclear ophthalmoplegia, dysarthria, and delayed-onset palatal myoclonus. Palatal myoclonus is thought to be secondary to delayed hypertrophic degeneration of the bilateral inferior olivary nuclei secondary to involvement of bilateral dentatoolivary tract. We describe a case of a patient with early-onset palatal myoclonus. CASE PRESENTATION: A 53-year-old Caucasian man with several vascular risk factors presented to our emergency room with slurred speech, double vision, difficulty with swallowing and walking, and rhythmic contractions of the soft palate...

BACKGROUND AND PURPOSE: T2*-weighted magnetic resonance angiography (SWAN) detects hemodynamic insufficiency as hypointense areas in medullary or cortical veins. We therefore investigated whether SWAN can help predict ischemic penumbra-like lesions in patients with acute ischemic stroke (AIS). MATERIALS AND METHODS: Magnetic resonance imaging (MRI) records-including SWAN, diffusion-weighted imaging (DWI), and magnetic resonance angiography (MRA)-of consecutive patients with major vessel occlusion within 6 h from AIS onset were analyzed...

A 27-year-old woman with a previously undiagnosed polyarteritis nodosa (PAN) developed lateral medullary stroke related to a thrombosed posterior inferior cerebellar artery (PICA)-origin aneurysm. A concurrent thrombosis of the PICA was identified on high-resolution 3-dimensional CUBE T1 magnetic resonance imaging sequence at 3 T. Body computed tomography angiography, magnetic resonance imaging-magnetic resonance angiography, and digital angiography revealed multiple tiny aneurysms of the visceral arteries and bilateral kidney infarcts...

[Purpose] The purpose of this study was to examine the effects of task-specific plantar flexor training on walking ability indices in a patient with a paretic ankle. [Subject and Methods] The subject was a 65-year-old male patient with right hemiplegia due to a left medullary ventral infarction. An ABA' single-subject design was adopted. The independent variable was a task-specific plantar flexor training exercise, similar to that during walking, targeting the paretic ankle. The dependent variables were the isometric ankle plantar flexor strength, maximum walking speed, step length, and trailing limb angle in the paretic terminal stance phase...

BACKGROUND: Lateral medullary infarction (LMI) is not an uncommon disease. Although lesions are usually restricted to the lateral medullary area, some patients have additional infarcts in other parts of the brain. The clinical features and prognosis of isolated LMI (pure LMI, LMIpr) have been investigated. However, it remains unclear whether clinical characteristics, prognosis and factors associated with prognosis differ between patients with LMIpr and those with additional lesions (LMI plus, LMIpl)...

Posterior inferior cerebellar artery (PICA) aneurysms are rare. The most common complication of intracranial aneurysms is rupture causing subarachnoid hemorrhage. Ischemic infarct, although more common in giant thrombosed aneurysms, is a very rare manifestation of small intracranial aneurysms. Here we describe a patient who presented with lateral medullary acute infarction associated with an ipsilateral, small (4 × 3.5 mm), unruptured and non-thrombosed PICA aneurysm.

The sustainability of captive cheetah populations is limited by high mortality due to chronic renal disease. This necropsy study, conducted on 243 captive cheetahs from one institution, investigated the relationships between focal palatine erosions, gastritis, enterocolitis, glomerulosclerosis, chronic renal infarcts, renal cortical and medullary fibrosis, and renal medullary amyloidosis at death. Associations between the individual renal lesions and death due to chronic renal disease and comparisons of lesion prevalence between captive bred and wild born and between normal and king coated cheetahs were also assessed...

Objective: Internal representation of gravity can be quantified by measuring the subjective visual vertical (SVV). Modulation of verticality perception during head tilts may be perturbed in vestibular disorders causing SVV tilts in the upright head position. This study aimed to determine the influence of head tilts on the estimation of SVV in acute vestibular disorders. Methods: We measured the SVV in 37 patients with acute vestibular symptoms due to unilateral vestibular neuritis (VN) ( n  = 28) and lateral medullary infarction (LMI) ( n  = 9)...

BACKGROUND: Secondary cervical dystonia is induced by organic brain lesions involving the basal ganglia, thalamus, cerebellum, and brain stem. It is extremely rare to see cervical dystonia induced by a medullary lesion. CASE PRESENTATION: We report a case of an 86-year-old Japanese woman who developed cervical dystonia following lateral medullary infarction. She developed sudden-onset left upper and lower extremity weakness, right-side numbness, and dysarthria. Brain magnetic resonance imaging revealed an acute ischemic lesion involving the left lateral and dorsal medullae...

Lateral medullary syndrome (LMS), also known as Wallenberg's syndrome, PICA syndrome, results from occlusion of the posterior inferior cerebellar artery, with associated infarction of parts of medulla oblongata, and cerebellum on the ipsilateral side. It often manifests as various patterns of sensory, motor, and autonomic deficits. While sensorimotor dysfunction presents as a predicted pattern of clinical signs and symptoms, autonomic dysfunction is usually less clinically apparent, and can be easily mistaken as a concomitant pathology in the end organ it affects...

In the elderly, myasthenia gravis (MG) can present with bulbar symptoms, which can be clinically difficult to diagnose from other neurological comorbid conditions. We describe a case of a 75-year-old man who had been previously diagnosed with dysphagia associated with medullary infarction but exhibited aggravation of the dysphagia later on due to a superimposed development of bulbar MG. After recovering from his initial swallowing difficulties, the patient suddenly developed ptosis, drooling, and generalized weakness with aggravated dysphagia...

BACKGROUND: Glucagon-like peptide-1 (GLP-1) receptor agonists are effective glucose-lowering drugs. Findings from cardiovascular outcome trials showed cardiovascular safety of GLP-1 receptor agonists, but results for cardiovascular efficacy were varied. We aimed to examine overall cardiovascular efficacy for lixisenatide, liraglutide, semaglutide, and extended-release exenatide. METHODS: In this systematic review and meta-analysis, we analysed data from eligible trials that assessed the safety and efficacy of GLP-1 receptor agonists compared with placebo in adult patients (aged 18 years or older) with type 2 diabetes and had a primary outcome including, but not limited to, cardiovascular mortality, non-fatal myocardial infarction, and non-fatal stroke...

OBJECTIVE: The parieto-insular vestibular cortex (PIVC) is a core region of vestibular input into regions of the cortex. The vestibular nuclei have reciprocal connections with the PIVC. However, little is known about injury of the core vestibular pathway to the PIVC in patients with dorsolateral medullary infarctions. In this study, using diffusion tensor tractography (DTT), we investigated injury of the neural connections between the vestibular nuclei and the PIVC in patients with typical central vestibular disorder...
