Case report describing the finding of central pontine myelinolysis (CPM) using combined fluorine-18 ( (18)F)-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). The patient was a known alcoholic who, during admission was under treatment for hyponatremia, showed a significant decline in both motor and cognitive function. Combined (18)F-FDG PET/CT showed localized FDG uptake in the pons, consistent with the finding of CPM observed on magnetic resonance imaging (MRI). CPM is a demyelinating lesion of the pons, resulting in several neurological symptoms...

We report the first patient with pathologically proven leukoencephalopathy associated with hypophosphatemia. A 61-year-old woman had repetitive episodes of decreased consciousness with pontine and pallidal lesions and extensive leukoencephalopathy on MRI, later found to be associated with hypophosphatemia. Although hypophosphatemia has been linked to central pontine and extrapontine myelinolysis (osmotic myelinolysis), lesions in the deep white matter have not been reported. Brain biopsy performed during the first diagnosis process revealed nonspecific demyelination with gliosis, a finding similar to that of chronic osmotic myelinolysis...

Central pontine myelinolysis (CPM) is a potentially-devastating complication of rapid osmolar shifts, classically attributed to overlyaggressive correction of chronic hyponatremia. Magnetic resonance imaging (MRI) allowed earlier diagnosis of CPM, but most importantly, it has revealed that the odds of good functional recovery are surprisingly high. A trident shaped pontine lesion is a typical finding in CPM (the trident sign). The "piglet sign" is a much less well-known radiologic finding in CPM. Due to the rarity of CPM, very little has been published on the evolution of these MRI findings...

A 21-year-old woman underwent surgery for a pituitary tumor. On the 11th postoperative day, blood examination revealed severe hyponatremia, with a serum sodium level of 111 mEq/l, and two days later this increased rapidly to 137 mEq/l. On the 20th postoperative day, the patient developed dysarthria and gait disturbance. Head MRI on the 30th postoperative day demonstrated intense high-signal lesions in the pons and bilateral corpus striatum on FLAIR and DWI, and central pontine and extrapontine myelinolysis was diagnosed...

Tumefactive demyelinating lesions (TDLs) that may resemble brain neoplasms or abscesses are uncommon but noteworthy. A solid knowledge of how to distinguish TDLs from malignancy or infection is a key step to avoid unnecessary medical or surgical interventions. Almost all the intracranial demyelination diseases after liver transplantation (LT) refer to central pontine myelinolysis or extrapontine myelinolysis; TDLs after LT have never been reported. In 2005, a 45-year-old Chinese male underwent orthotopic LT due to "acute on chronic liver failure" in our hospital...

Central pontine myelinolysis (CPM) is a rare condition usually caused by rapid sodium correction in hyponatraemia after a severe neurological syndrome. Only few cases have been reported during pregnancy, most of which were reported in patients with hyperemesis. We describe the successful management of the first case of twin pregnancy in a patient who presented with CPM after treatment for premature labour and then review the literature on CPM in pregnancy (aetiology, diagnosis and management). Our patient required emergency delivery to achieve electrolyte and fluid balance...

Central pontine myelinolysis (CPM), also known as osmotic demyelination syndrome, is a rare demyelinating disorder characterized by the loss of myelin in the center of the basis pontis. In this case report, an alcoholic patient with CPM and acquired demyelinating lesion of the basis pontis is described. The patient is a 70 year-old woman who presented with intermittent psychiatric symptoms and limb tremors following two months of alcohol abuse. During admission, magnetic resonance imaging (MRI) revealed hyperintensity on T2 weighted images and fluid-attenuated inversion-recovery imaging in the central pons without contrast enhancement...

PURPOSE: We had recently reported one case at American Journal of Emergency Medicine about centralvariant posterior reversible encephalopathy syndrome (PRES) in an 84-year-old woman with an initial misdiagnosis as central pontine myelinolysis (CPM). Here, we introduce another case of centralvariant PRES in a 49-year-old man mimicking as acute brainstem infarction in the cranial computed tomography (CT) findings. CASE REPORT: A 49-year-old man was admitted to the emergency department with a 5-day history of vertigo, cognitive decline, and difficulty in walking...

White matter diseases include a wide spectrum of disorders that have in common impairment of normal myelination, either by secondary destruction of previously myelinated structures (demyelinating processes) or by primary abnormalities of myelin formation (dysmyelinating processes). The pathogenesis of many white matter diseases remains poorly understood. Demyelinating disorders are the object of this review and will be further divided into autoimmune, infectious, vascular, and toxic-metabolic processes. Autoimmune processes include multiple sclerosis and related diseases: tumefactive demyelinating lesions, Balo concentric sclerosis, Marburg and Schilder variants, neuromyelitis optica (Devic disease), acute disseminated encephalomyelitis, and acute hemorrhagic leukoencephalopathy (Hurst disease)...

Central pontine myelinolysis (CPM), a potentially fatal and debilitating neurological condition, was first described in 1959 in a study on alcoholic and malnourished patients. It is a condition most frequently related to rapid correction of hyponatremia. Chronic alcoholism associated CPM tends to be benign with a favorable prognosis compared to CPM secondary to rapid correction of hyponatremia. We describe a normonatremic, alcoholic patient who presented with CPM after a rapid rise in his sodium levels. Our case illustrates the fact that CPM can manifest even in patients who are normonatremic at baseline...

Rapid correction of hyponatremia is known to cause central pontine myelinolysis (CPM). It may concurrently involve other areas of brain as well, referred as extra-pontine myelinolysis (EPM). Isolated EPM however is a very rare occurrence. We present a case of EPM where the hyponatremia was secondary to hypothyroidism due to empty sella syndrome. Chronic hyponatremia should always be corrected slowly to avoid such osmotic myelinolysis syndromes (OMS).

Posterior reversible encephalopathy (PRES) is a condition characterized by T2 and FLAIR hyperintensities in magnetic resonance imaging (MRI) studies, localized preferentially in the occipital-parietal white matter regions. Pathological MRI images located in midbrain, pons, medulla and spinal cord, that could be asymptomatic, were recently included in this entity. These images are interpreted as vasogenic edema, which is caused by arterial hypertension or eclampsia, neurotoxicity related to immunosuppressive agents or chemotherapy, among other causes...

Rapid correction of hyponatremia is a well-known cause of central pontine and extrapontine myelinolysis. But uncommonly seen and rarely reported in Hypernatraemia. We report a rare case presenting as postpartum psychosis, wherein imaging revealed myelinolysis of corticospinal tracts in wine glass distribution and empty delta sign due to cortical venous thrombosis. At follow-up 3 months later, revealed significant neurological improvement. Concurrance occurrence of this dual pathology is not been described, which in our case was due to high serum sodium levels at presentation and dehydration...

Extrapontine myelinolysis (EPM) is an uncommon disorder in children, with few pediatric cases reported to date. We report the first case of an infant with EPM without central pontine myelinolysis (CPM) presenting with severe hypernatremia. On admission, the infant had impaired consciousness, mild dehydration, and severe hypernatremia (190 mmol/L). The following day, the patient developed abnormal involuntary movements. Brain magnetic resonance imaging (MRI) confirmed EPM without CPM. He recovered without sequelae, and clinical examinations were within normal limits approximately 6 months after discharge...

Harry Donnelly, Steve Connor, Jennifer Quirk
Central pontine myelinolysis is characterised by focal osmotic demyelination within the pons. Its clinical presentation varies, but may include acute paralysis, dysarthria and dysphagia. The cause is traditionally associated with overzealous correction of hyponatraemia in patients who are malnourished, alcoholic or chronically ill. However, it may develop in the context of normal serum sodium, since rapid gradient shifts in brainstem osmolalities can occur in other ways. We present an unusual example of central pontine myelinolysis caused by osmotic shifts secondary to hyperglycaemia in a person with type 1 diabetes mellitus and with consistently normal serum sodium concentrations...
