Background: We present two patients with the Lewis-Sumner variant of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP), charting the diagnostic challenge posed by their clinical presentation and electrodiagnostic findings. The learning points center on the use of magnetic resonance imaging (MRI) in establishing a definitive diagnosis when clinical and neurophysiology data do not otherwise add up. Cases: The first patient presented with slowly progressive asymmetric distal weakness of the lower limbs with wasting, weakness, areflexia and numbness on examination. The second patient experienced stepwise asymmetric hand/forearm weakness with deformity and areflexia, plus mild distal sensory impairment. Neurophysiological studies for both patients were initially most suggestive of mononeuritis multiplex, with no evidence of demyelination. Conclusion: The possibility of asymmetric or multifocal CIDP, the Lewis-Sumner variant, should not be forgotten in suspected mononeuritis multiplex and the value of MRI in such cases is discussed.

AbstractCentral nervous system (CNS) tumors are the most common solid tumors in children and adolescents. However, in neonates and children aged younger than a year, they are very rare. Clinical presentation in neonates is often subtle and nonspecific. When neurological symptoms are apparent at this age, cranial ultrasound (CUS) is often done as the initial evaluation, with a standard approach through the anterior fontanel (AF), followed by further imaging, such as magnetic resonance imaging (MRI), if necessary. We report the first neonatal case of a rapidly progressive diffuse midline glioma positive for histone H3 K27M mutation (World Health Organization [WHO] grade IV) in which using extended (transmastoid) CUS studies through the mastoid fontanelle (MF) in the second month of life defined the lesion in the brainstem.

Gh Excess

Acromegaly is a condition of excessive somatic growth and distorted proportion due to hypersecretion of growth hormone(GH) and insulin-like growth factor 1 (IGF-1). Insidious clinical manifestation of GH excess as a result of GH-secreting pituitary adenoma renders acromegaly a disease with typically delayed diagnosis. We report a 29-year old male planned to undergo reconstruction of the nose. The patient was referred for medical tness. Given the clinical features consistent with acromegaly the patient was evaluated further for diagnosis. Laboratory investigation showed raised IGF-1and non-suppressed GH post 75gms glucose, amid normal cortisol, corticotropin(ACTH), prolactin, testosterone, and thyroid function tests. He did not have dysglycemia. Magnetic resonance imaging (MRI) of the pituitary revealed a pituitary macroadenoma consistent with acromegaly. This case highlights the notable absence of recognizing the clinical presentation of acromegaly in this patient by his medical care physician and surgeons, and therefore the importance of thorough history taking, attention, and observation in making a new diagnosis that has the potential to alter a patient's health care and alleviate impending complications, morbidity and/or mortality

Progressive Dysphagia

A 52-year-old woman was referred for a progressive neurological condition which started a year before with continuous irregular twitching of the right facial and arm muscles as well as the tongue and palate, followed by progressive dysphagia, right hemiparesis, ataxia, dysphasia and dysarthria. Though magnetic resonance imaging (MRI) at clinical presentation and a year after were both normal (Figure A1), Rasmussen's encephalitis (RE) was strongly suspected and treatment with corticosteroids and immunoglobulins were begun. A third MRI, two years after onset, revealed mild T2 hyperintense subcortical white matter changes over the left perisylvian region (Figure A) which confirmed our initial suspicion of RE as she now met clinical, electrophysiological and morphological criterias for RE. While waiting for a cerebral biopsy after unsatisfactory response from antiepileptic drugs, corticosteroids and immunoglobulins, her condition markedly worsened less than three years after onset with the sudden occurrence of status epilepticus requiring intubation and continuous infusions of midazolam and propofol.

Carcinomatous encephalitis is a rare entity, originally described by Madow and Alpers in 1951, which is characterized by tumoral spreading perivascular, without mass effect. Clinical manifestations such as hemiparesis, seizures, ataxia, speech difficulties, cerebrospinal fluid findings as well as computed tomography are nonspecific. This leads the physician to pursue more frequent diseases that could explain those manifestations - toxic, metabolic, and/or infectious encephalopathy. A magnetic resonance imaging (MRI) with gadolinium, the method of choice, presumes the diagnosis. Previous reports of this unusual form of metastatic disease have described patients with prior diagnosis of pulmonary adenocarcinoma. We present the case of carcinomatous encephalitis in a 76-years-old woman as the primary manifestation of occult pulmonary adenocarcinoma with its clinical, imaging, and anatomopathological findings.

Introducción: El síndrome del espacio cuadrilátero (QSS) es un cuadro clínico causado por la compresión nerviosa y/o vascular a nivel del espacio axilar lateral. La prevalencia de este síndrome se desconoce y se cree que es baja, sin embargo, formas de presentación incompleta podrían llevar a que el mismo sea subdiagnosticado. Objetivo: Describir un protocolo diagnóstico utilizado en una serie de casos consecutivos de pacientes con omalgia inespecífica y sospecha de QSS. Materiales y Métodos: De manera prospectiva se evaluaron 10 pacientes con omalgia agravada con la rotación externa forzada, uno de ellos con síntomas bilaterales. Se realizó electromiografía (EMG) de deltoides y redondo menor bilaterales, con estudios de conducción nerviosa. Los valores se compararon con el hombro sano, y con un grupo control. El diagnóstico se confirmó mediante resonancia magnética nuclear (RMN). Resultados: El EMG mostró en todos los casos atrapamiento con compromiso axonal de la rama para el redondo menor, con preservación de la inervación del deltoides. La RMN mostró en los 11 hombros afectados atrofia selectiva del redondo menor. Conclusión: El QSS en sus formas incompletas suele ser subdiagnosticado, siendo necesario mantener un alto índice de sospecha clínica frente a un cuadro de omalgia inespecífica. Palabras Claves: espacio cuadrilátero, omalgia, electromiografía, redondo menor, nervio axilar. Introduction: The quadrilateral space syndrome (QSS) has clinical features caused by a nervous and /or vascular compression at the lateral axillary space. The prevalence of this syndrome is unknown but it is believed to be low. Nevertheless, some cases with an incomplete clinical presentation might be misdiagnosed. Purpose: To describe a diagnostic protocol used in a series of consecutive cases of patients with non-specific omalgia and suspected QSS. Materials and Methods: Ten patients of both genders suffering shoulder pain aggravated by forced external rotation were prospectively evaluated.  One of them had bilateral symptoms. Evaluation included clinical examination, electromyography (EMG) and nerve conduction studies of the deltoid and teres minor bilaterally. The results were compared with an age-matched control group. Diagnosis was confirmed by magnetic resonance imaging (MRI). Results: The EMG showed in all the cases a selective entrapment of the branch for the teres minor, with preservation of the innervation of the deltoid. The RMN showed in the 11 affected shoulders selective atrophy of the teres minor. Conclusion: Incomplete presentations of the QSS are usually underdiagnosed, making it necessary to maintain a high index of clinical suspicion in front of any non-specific omalgia case. Key words: quadrilateral space, omalgia, electromyography, teres minor, axillary nerve.

We report the case of a post-progressive multifocal leukoencephalopathy (PML), multiple sclerosis (MS) patient with an uncomplicated pregnancy and delivery. A 28-year-old woman on natalizumab (total of 49 infusions) was diagnosed with PML due to typical magnetic resonance imaging (MRI) and clinical presentation. John Cunningham virus (JCV) was detected in the cerebrospinal fluid (CSF) during the immune reconstitution inflammatory syndrome (IRIS). Nine months after PML onset, JCV negativity in the CSF was observed. MS was stabilised with dimethyl fumarate (DMF), and 18 months later, a desired pregnancy was reported, resulting in the birth of a healthy boy. Our report gives new hope regarding family planning for post-PML patients.

<p>Determining the origin of lameness and pain in dog shoulder structures is considered a diagnostic challenge. Ultrasonography is an important diagnostic tool, capable of dynamically providing detailed information on muscle-tendon structures at a low cost. Its diagnostic accuracy for shoulder injuries is comparable to that of magnetic resonance imaging (MRI); however, the technique is still underestimated and underused in orthopedic examinations of small animals in Brazil. This study aimed to compile the literature data and explore the findings of ultrasound examinations for the diagnosis of abnormalities in the shoulder joint region of dogs. Scanning maneuvers of the tendons of the biceps brachii, supraspinatus, infraspinatus, teres minor, humeral head, and brachial plexus muscles were reviewed. The normal ultrasonographic patterns and findings that characterize different illnesses in this region were described.</p>

Retroperitoneal lymphangiectasia is a very rare lymphatic disorder characterized by abnormal proliferation of lymphatics. We present series of 3 cases of retroperitoneal lymphangiectasia which are diagnosed in our institute with the help of Ultrasonography (USG), Computed Tomography (CT) and Magnetic resonance imaging (MRI) of abdomen and pelvis with unusual clinical presentation. We include clinical features and imaging findings of this disorder with its pathogenesis and diagnosis. Two of the cases were clinically masquerading as hernia and one case was mimicking varicocele. Thorough clinical examination and USG, colour Doppler, CT and MRI are extremely helpful imaging investigation that aid in differentiating these lesions from hernia/ varicocele and the cross sectional imaging like CT and MRI can  depict the anatomical extent of the disease.

Spinal cord ischemia most often presents as an anterior spinal artery syndrome and involves watershed regions of the spinal cord. The clinical presentation and etiologies can be heterogeneous, but cord infarcts are typically the result of aortic surgeries, systemic hypotension, vertebral artery and aortic dissections, embolus, or vascular malformations. Given that it is a rare entity, involving symptoms that can progress over minutes to hours, a diagnosis is often delayed until after conventional windows for revascularization, including thrombolysis, have passed. Magnetic resonance imaging (MRI) is usually required to confirm the diagnosis.

A 55 year old female patient presented with progressive back pain of 6 month duration,aggravated on lying down, associated with weakness and numbness of the bothlower limbs for since 4 months. On neurological examination, the tone was foundincreased in both the lower limbs with a subjective power of grade 3/5 in both thelower limbs. Ankle and knee jerks were brisk with hypoaesthesia below D12dermatomes bilaterally, plantars were extensor. A clinical diagnosis of involvement ofD9 spinal level lesion was made. Magnetic resonance imaging (MRI) of the dorsolumbarspine showed an intraduralextramedullary ventrally placed lesion at the D8–D9 vertebral level with significant compression of the spinal cord [Figure 1, 2, 3]. Thelesion appeared hyperintense on T2W image with no contrast enhancement and withsignificant compression and shifting of the cord to the left. After preoperative routinehematological investigations, she underwent operation by laminectomy of D8–D9vertebrae and total excision of the cystic lesion was performed [Figure 4, 5]. Histologicalexamination revealed respiratory type pseudostratified ciliated columnar cells and apathological diagnosis of bronchogenic cyst was rendered [Figure 6]. The patient hadan uneventful postoperative period with subjective improvement of her symptomswith reduced spasticity & improvement of motor grade to 4/5 in both lower limbs. Bang.
