Corticobasal syndrome (CBS) is characterised by asymmetrical parkinsonism and cognitive impairment. The underlying pathology varies between corticobasal degeneration, progressive supranuclear palsy, Alzheimer's disease, Creutzfeldt-Jakob disease and frontotemporal lobar degeneration sometimes in association with GRN mutations. A 61-year-old male underwent neurological examination, neuropsychological assessment, MRI, and HMPAO-SPECT at our medical centre. After his death at the age of 63, brain autopsy, genetic screening and mRNA expression analysis were performed. The patient presented with slow progressive walking disabilities, non-fluent language problems, behavioural changes and forgetfulness. His family history was negative. He had primitive reflexes, rigidity of his arms and postural instability. Later in the disease course he developed dystonia of his left leg, pathological crying, mutism and dysphagia. Neuropsychological assessment revealed prominent ideomotor and ideational apraxia, executive dysfunction, non-fluent aphasia and memory deficits. Neuroimaging showed symmetrical predominant frontoparietal atrophy and hypoperfusion. Frontotemporal lobar degeneration (FTLD)-TDP type 3 pathology was found at autopsy. GRN sequencing revealed a novel frameshift mutation c.314dup, p.Cys105fs and GRN mRNA levels showed a 50% decrease. We found a novel GRN mutation in a patient with an atypical (CBS) presentation with symmetric neuroimaging findings. GRN mutations are an important cause of CBS associated with FTLD-TDP type 3 pathology, sometimes in sporadic cases. Screening for GRN mutations should also be considered in CBS patients without a positive family history.

Motor neurone disease (MND) is a rapidly progressive neurodegenerative condition. It affects people of all ages, but is more common with increasing age (especially over 50 years) and men are affected twice as often as women. The causes remain unknown, although around 5% of cases have a genetic basis. Survival is usually only three to five years from diagnosis. MND affects both upper and lower motor neurones, with variable contributions. The nerve involvement in MND usually has a focal onset, is asymmetrical, but tends to spread to adjacent regions of the body. If the affected region is in the legs, a common presenting feature is tripping, falls or foot drop. If it is in the arms there may be difficulty with fine tasks such as fastening buttons, or raising an arm, and if the cranial nerves are affected there may be slurring of speech, or difficulty swallowing. Key to the diagnosis is evidence of progression, and this may lead to some delay in considering and also confirming the diagnosis. When examining the patient, evidence of more widespread neuromuscular involvement should be looked for. In a patient with foot drop, and fasciculation of the tongue, MND would be a likely diagnosis. Upper motor neurone involvement may be readily determined by examining the reflexes. Brisk reflexes, in the arms, legs or jaw, in the context of features of lower motor neurone denervation are highly suggestive of MND. Suspicion of MND should lead to referral for a neurology opinion. The most useful investigation is likely to be EMG with nerve conduction studies, and probably MRI scan of relevant areas. Blood tests are arranged to screen for any other causative condition. Riluzole is a disease modifying drug licensed to extend the life of patients with MND. There is no treatment that will reverse, or halt, progression of the disease.

Corticobasal degeneration is a degenerative disease characterized by asymmetric brain atrophy and clinically by asymmetric onset of an akinetic-rigid syndrome with apraxia, dysarthria and dysphagia. Diagnosis must be confirmed by autopsy. We have investigated the ability of MRI to detect asymmetric atrophy to support the clinical diagnosis and permit differential diagnosis against other degenerative disorders. Ten patients with clinical suspicion of corticobasal degeneration were studied by brain MRI, and the images were reviewed with the side of greater clinical involvement unknown to the reviewer. The original reports of MR scans were also reviewed. MRI demonstrates that cortical atrophy is asymmetric and more marked in the posterior frontal and mainly in the parietal regions on the side contralateral to the clinical symptoms. Asymmetry was rarely detected on the first reading. Our review of MRI findings demonstrates that it is possible to detect asymmetrical parietal atrophy, thus supporting the clinical diagnosis of corticobasal degeneration. It is essential to be aware of the disease and alert for asymmetries in order to discern the more involved side. No abnormalities were detected in the basal ganglia.

Progressive muscle atrophy is a rare subtype of motor neuron disease that affects only the lower motor neurons and presents as asymmetrical rapidly progressive muscle weakness, atrophy and normal sensations. The diagnostic electrophysiological findings are denervation potentials in three out of four body segments (bulbar, cervical, thoracic and lumbosacral). The disease is fatal and the management is supportive. We present the report of a 45-year-old female patient who presented with unilateral foot drop and rapidly progressed to profound weakness in muscles of all limbs, neck and back along with dysarthria and dysphagia. She had been operated twice for suspected cervical and lumbosacral intervertebral disc herniations and ultimately guided in right direction after muscle biopsy, nerve conduction studies and electromyography.

Sarcoidosis is a multisystem disorder of unknown etiology, characterized pathologically by the presence of nonnecrotizing granulomatous inflammation in affected organs. Although skeletal muscle is involved in 50-80 percent of individuals with sarcoidosis, symptomatic myopathy has been shown to be a rare manifestation of the disease. Inclusion body myositis (IBM) is a rare acquired idiopathic inflammatory myopathy with the insidious onset of asymmetric and distal muscle weakness that characteristically involves the quadriceps, tibialis anterior, and forearm flexors. Moreover, dysphagia can be the presenting complaint in one-third of patients. Herein, we are presenting a case of 67-year-old African American female who presented with one-month history of new onset progressive dyspnea on exertion. She was diagnosed with stage IV sarcoidosis based on chest CT scan findings and transbronchial lung biopsy revealing nonnecrotizing granulomatous inflammation. Over the next three months after her diagnosis, she presented to the hospital with progressive dysphagia associated with asymmetrical distal muscle weakness. A quadriceps muscle biopsy revealed features consistent with inclusion body myositis. We are reporting this case as it may support the hypothesis of sarcoidosis being a trigger that possibly promotes the development of inclusion body myositis, leading to a very poor prognosis.

Ehlers-Danlos syndrome is a hereditary connective tissue disorder that has gastrointestinal manifestations in over 50% of its cases. We present the first case of bariatric surgery in a patient with Ehlers-Danlos syndrome and outline management challenges in the context of the relevant literature. A 56-year-old man with type IV Ehlers-Danlos syndrome and a body mass index of 41.8 kg/m2 was referred to the bariatric centre of the Churchill Hospital, Oxford, for consideration of surgery for morbid obesity. His comorbidity included type 2 diabetes, hypertension, dyslipidaemia and obstructive sleep apnoea. He underwent a laparoscopic Roux-en-Y gastric bypass. His initial recovery was uneventful and he was discharged on the first postoperative day. Six weeks later, he presented with 43.9% excess weight loss and improved glycaemic control. Three months postoperatively, however, he complained of dysphagia, regurgitation and postprandial pain. A barium meal and gastroscopy suggested the presence of a gastric diverticulum. A surgical exploration was planned. Intraoperative gastroscopy demonstrated an asymmetrical gastric pouch dilatation and the pouch was therefore refashioned laparoscopically. Despite the initial symptomatic relief, two months later he experienced retrosternal pain with progressive dysphagia. Since then, multiple endoscopic dilatations of the gastro-oesophageal junction have been performed for recurrence of symptoms. Finally, a laparoscopic hiatus hernia repair and adhesiolysis was performed resulting in complete relief of patient's symptoms. Bariatric management of patients with Ehlers-Danlos syndrome can prove challenging. The bariatric team must implement a careful management plan including a detailed consent process, a tailored surgical intervention and a follow-up focused on potential gastrointestinal manifestations.
