Pyogenic sacroiliitis is rare and accounts for approximately 1-2% of osteoarticular infections in children. Considerable delay between presentation and diagnosis is recognized. Two cases of pyogenic sacroiliitis are described. The first case is a 28-month-old girl presented with acute onset of fever, pain in the left hip, and limpness. Computed tomography (CT), bone scans, and magnetic resonance imaging (MRI) of the pelvis showed characteristic findings of infectious sacroiliitis, and blood cultures were negatives. The second case is a 13-year-old girl presented with acute onset of fever, pain in the right hip, and buttock, with inability to walk. The diagnosis of pyogenic sacroiliitis was confirmed by bone scans, and CT of the pelvis and blood cultures have identifiedProteus mirabilis. The two children recovered fully after 6 weeks of antimicrobial therapy. Pyogenic sacroiliitis is an uncommon disease in children. The key to successful management is early diagnosis in which CT, bone scans, and MRI findings play a crucial role. If the diagnosis is established promptly, most patients can be managed successfully with antimicrobial therapy.

Introduction : Double hearing or Diplacusis is a synchronous double perception of a sound and can have Binauralis or Monauralis pattern, with inner ear disorders being the main culprit [1] . Other forms of Auditory illusions have been reported as a co‐manifestation of stroke syndromes, but none as an isolated presentation [1][2] . This is a case of a 77‐year‐old male with acute onset isolated Diplacusis in a patient due to a right temporal lobe ischemic infarct. To our knowledge, this is the first case report of an isolated diplacusis due to cortical infarct. Methods : A case presentation with Pubmed search of review articles and case reports. Results : The patient had a past medical history of sensorineural deafness in his left ear. He described any sound heard as the same quality but occurring with an echo heard a fraction of a second later in his right ear. There was no decreased hearing quality or tinnitus reported in his right ear. His drug screen test was negative. His examination was only remarkable for a sensorineural hearing loss pattern on his left ear. His (NIHSS) was zero, and no other cranial nerve abnormalities were detected. His MRI was significant for a punctate restricted diffusion on the right temporal lobe, resembling an ischemic infarct (Figure). Conclusions : Isolated diplacusis can present as acute ischemic stroke in the temporal lobe. Further studies are needed to understand its pathophysiology.

Objective: Takayasu arteritis is a rare granulomatous chronic vasculitis that affects the aorta and its main branches. Neurologic manifestations can accompany the disease; however, there is no study on neuroimaging in children with Takayasu arteritis. Therefore, we aimed to evaluate cranial magnetic resonance imaging (MRI) in pediatric Takayasu arteritis patients. Materials and Methods: Demographic, clinical, and laboratory data were obtained retrospectively. Results: The study included 15 pediatric Takayasu arteritis patients. All patients presented with constitutional symptoms. Additionally, 6 patients suffered from headache, 2 had syncope, 1 had loss of consciousness, and 1 had convulsion. All patients underwent cranial and diffusion MRI a median 12 months after diagnosis. Cranial MRI findings were normal in 12 patients, whereas 3 patients had abnormal findings, as follows: stenosis in the M1 and M2 segments of the left middle cerebral artery (n = 1); diffuse thinning of the right internal carotid, middle cerebral, and right vertebral and basilar artery (n = 1); as a sequela, areas of focal gliosis in both the lateral ventricular and posterior periventricular regions (n = 1). Among these 3 patients, 1 had no neurologic complaints. Conclusion: Abnormal MRI findings can be observed in pediatric Takayasu arteritis patients, even those that are asymptomatic; therefore, clinicians should carefully evaluate neurologic involvement in all pediatric Takayasu arteritis patients.

A hallmark of brain injury from infection, vascular, neurodegenerative, and other disorders is the development of gliosis, which can be detected by magnetic resonance imaging (MRI). In rodent models of diet-induced obesity (DIO), high-fat diet (HFD) consumption rapidly induces inflammation and gliosis in energy-regulating regions of the mediobasal hypothalamus (MBH), and recently we reported MRI findings suggestive of MBH gliosis in obese humans. Thus, noninvasive imaging may obviate the need to assess MBH gliosis using histopathological end points, an obvious limitation to human studies. To investigate whether quantitative MRI is a valid tool with which to measure MBH gliosis, we performed analyses, including measurement of T2relaxation time from high-field MR brain imaging of mice fed HFD and chow-fed controls. Mean bilateral T2relaxation time was prolonged significantly in the MBH, but not in the thalamus or cortex, of HFD-fed mice compared with chow-fed controls. Histological analysis confirmed evidence of increased astrocytosis and microglial accumulation in the MBH of HFD-fed mice compared with controls, and T2relaxation times in the right MBH correlated positively with mean intensity of glial fibrillary acidic protein staining (a marker of astrocytes) in HFD-fed animals. Our findings indicate that T2relaxation time obtained from high-field MRI is a useful noninvasive measurement of HFD-induced gliosis in the mouse hypothalamus with potential for translation to human studies.

We report the case of a 62-year-old patient with lower back pain radiating into the right leg accompanied by numbness. The pain had an acute onset and was resistant to conservative pain treatment. A magnetic resonance imaging (MRI) scan of the lumbar spine showed no degenerative discovertebral lesions, but a swelling of the nerve root supplying the affected dermatome. For pain treatment the patient received lumbar epidural infiltrations. During this treatment the patient suddenly developed a skin rash with grouped vesicular blisters on an erythematous ground. After the diagnosis of a lumbar herpes zoster and an acyclovir treatment, the patient could be discharged in an ameliorated condition. This case demonstrates the importance to consider rare causes of lumbosciatic pain and disorders and to acknowledge unspecific changes in a MRI scan.

Abstract Introduction. Leprosy is a disease that predominantly affects the skin and peripheral nerves, resulting in neuropathy and associated long-term consequences, including deformities and disabilities. According to the WHO classification, there are two categories of leprosy, paucibacillary (PB) and multibacillary (MB). The standard treatment for leprosy employs the use of WHO MDT (Multi Drug Treatment) regimen, despite its multiple downsides such as clofazimine-induced pigmentation, dapsone-induced haematological adverse effects, poor compliance due to long therapy duration, drug resistance, and relapse. Multiple studies and case reports using ROM regimen have reported satisfactory results. Nevertheless, there are still insufficient data to elucidate the optimum dosage and duration of ROM regimen as an alternative treatment for leprosy. Previous experience from our institution revealed that ROM regimen given three times weekly resulted in a satisfactory outcome. Case Reports. We report two cases of leprosy treated with ROM regimen from our institution. The first case was PB leprosy in a 64-year-old male who presented with a single scaly plaque with erythematous edge on the right popliteal fossa. Sensibility examination showed hypoesthesia with no peripheral nerve enlargement. Histopathological examination confirmed Borderline Tuberculoid leprosy. ROM regimen was started three times weekly for 6 weeks and the patient showed significant clinical improvement at the end of the treatment with no reaction or relapse until after 6 months after treatment. The second case was MB leprosy in a 24-year-old male patient with clawed hand on the 3rd-5th phalanges of the right hand and a hypoesthetic erythematous plaque on the forehead. Histopathology examination confirmed Borderline leprosy. The patients received ROM therapy 3 times a week with significant clinical improvement after 12 weeks. Conclusion. ROM regimen given three times weekly for 6 weeks in PB leprosy and 12 weeks in MB leprosy resulted in a significant clinical improvement. Thus, ROM regimen could be a more effective, safer, faster alternative treatment for leprosy.

Rapid Regression

In April 2015, a 20-year-old woman with multiple sclerosis (MS) presented with acute onset of repetitive abnormal postures and choreatic movements of the right arm, precipitated by voluntary movements (online video 1 and 2). Brain magnetic resonance imaging (MRI) showed a new active MS lesion involving the basal ganglia on the left side (Figure 1(a)). Intravenous steroid treatment resulted in rapid regression of this paroxysmal kinesigenic dyskinesia (PKD)-like hyperkinetic movement disorder. The patient became asymptomatic within 3 months. PKD is characterized by recurrent uni- or bilateral choreoathetosis and usually represents an autosomal dominant inherited disorder caused by PRRT2 gene mutations. As in the present case, a PKD-like phenotype may be associated with MS relapses in presumably genetic negative cases.

Background The acute onset of Marchiafava-Bignami disease (MBD) is difficult to capture, and its clinical manifestations are overlapped. Magnetic resonance imaging (MRI) is very useful in the diagnosis of acute MBD. Purpose To investigate the MRI features and clinical outcomes of acute MBD. Materials and Methods Sagittal T2-weighted (T2W) or T1-weighted (T1W) imaging, axial T1W and T2W imaging, and axial FLAIR and diffusion-weighted imaging (DWI) sequences were performed in 17 patients with acute MBD on 1.5-T MR. According to the different ranges of callosal restricted diffusion, MBD was divided into Type I (n = 7, the completely involved), Type II (n = 5, the mostly involved), and Type III (n = 5, the partly involved). The MRI findings and outcomes of each type were retrospectively analyzed. Results With the reduced range of the callosal restricted diffusion, the callosal atrophy or cavitation was more common: no case of Type I; 1 (20%) case of Type II; and 3 (60%) cases of Type III. With the increased range of callosal restricted diffusion, the extracallosal involvement was more common: 6 (86%) cases of Type I; 3 (60%) cases of Type II; and 1 (20%) case of Type III. During the follow-up, five cases had neuropsychiatric sequelae: 1 (14%) case of type I; 1 (20%) case of Type II; 3 (60%) cases of Type III. Conclusion The MRI findings and clinical outcomes of acute MBD are regular. The extensive restricted diffusion of acute MBD may present the curable condition. Callosal heterogeneity may affect the outcome of acute MBD.

A 22-year-old female was seen in the emergency within one hour of acute onset of right sided headache followed by weakness of the left side of body. On neurological examination, she was mildly drowsy, had forced right gaze deviation, dysarthria, left hemiplegia and left hemisensory loss. Computed tomography (CT) scan revealed early ischemic changes in the right middle cerebral artery (MCA) territory. The CT angiography done showed evidence of dissection of the supraclinoid segment of the right internal carotid artery with reduced flow distally into the MCA, which was confirmed by a conventional angiogram. In view of the intracranial carotid dissection, the patient was not treated with intravenous tissue plasminogen activator. Magnetic resonance imaging (MRI) of the brain done on the next day revealed evidence of acute ischemic lesions in the right MCA and anterior cerebral artery territory on diffusion-weighted imaging (DWI), with normal brainstem. [Figure 1] A repeat MRI performed 13 days after ictus showed hyperintense signal on DWI in the right cerebral peduncle which was hypointense on apparent diffusion coefficient (ADC) map suggestive of Wallerian-like degeneration. [Figure 2] The signal changes were less conspicuous on T2-weighted images. She had antigravity strength in the left leg but remained weak in her left arm at one month.

A 74-year-old man presented with a four week history of behavioural disturbances, upper and lower extremity numbness and impaired balance. He had been treated with metronidazole for six months for osteomyelitis of the right hallux. Examination revealed encephalopathy, and glove-and-stocking sensory loss to pinprick with reduced vibration threshold at the toe. The gait was wide based and ataxic. Nerve conduction studies showed a large fibre sensory-motor axonal polyneuropathy. Magnetic resonance imaging (MRI) revealed a solitary restricted diffusion lesion in the splenium of the corpus callosum (Figure A, B) with subtle prolongation of T2 (Figure C). The radiographic differential diagnosis included hypoglycaemia, viral encephalitis, antiepileptic drug toxicity/withdrawal and metronidazole toxicity. The combination of the imaging finding with the history of prolonged metronidazole use suggested metronidazole induced encephalopathy.
