Imaging findings of gallbladder duplication due to two cases: case report and review of literature

WOS: 000208903500015PubMed ID: 23243652Duplication of the gallbladder, a rare congenital anomaly, is important in clinical practice as it may cause some clinical, surgical, and diagnostic problems. This anomaly is also important for surgeons due to the increased risk of complications especially after laparoscopic cholecystectomy. We report ultrasonography, computed tomography, and magnetic resonance cholangiopancreatography findings in two cases of a symptomatic duplicated gallbladder

Transient splenial lesion in a case with carbon monoxide poisoning: A clue supporting the excitotoxicity hypothesis?

WOS: 000363346400016PubMed: 26277728Transient splenial lesions of the corpus callosum are uncommon radiologic findings seen in a number of clinical conditions. Awareness of these lesions is crucial to prevent further invasive investigation and intervention. We report a unique case of transient splenial lesion in a patient with carbon monoxide poisoning.

Percutaneous drainage for isolated pancreatic injury: A minimally invasive solution

Isolated traumatic rupture of the pancreas is an uncommon presentation with a rate of less than 5% of cases of major abdominal trauma. The proper management of peripancreatic fluid collections following pancreatic trauma is still uncertain. We present a patient with isolated pancreatic injury that was managed with percutaneous drainage. A 22-year-old male patient, who had fallen from a tree 3 days previously, was admitted to our clinic with symptoms of vomiting and abdominal distention. Laboratory results demonstrated leucocytosis (20.100/mm3) and elevated amylase levels (754 IU/L, n = 25-100 IU/L). Radiological diagnosis of a pancreatic injury associated with multiple peripancreatic fluid collections (the largest with a diameter of 100 mm and times; 40 mm and times; 75 mm) was established using ultrasonography (US). Computed tomography (CT) confirmed pancreatic transection. Conservative treatment, including somatostatin, was administrated and 5 days later percutaneous drainage catheters were placed under US guidance due to enlargement of the cystic collections (170 mm and times; 85 mm and times; 65 mm) and clinical progression. Seventeen days later, after confirming the regression of the fluid collections by US, the catheters were removed. No morbidity was observed and the control CT was normal. In hemodynamically stable patients, the percutaneous drainage procedure is one of the easiest and simplest ways to treat posttraumatic pancreatic fluid collections with less morbidity.

Bright and Dark Vessels on Stroke Imaging: Different Sides of The Same Coin?

PURPOSE Prominent hypointense cerebral vessels on susceptibility-weighted imaging (SWI) and the hyperintense vessel sign (HVS) on fluid-attenuated inversion recovery (FLAIR) imaging are considered as markers of compromised tissue perfusion in cerebral ischemia. In this study, we aimed to identify the correlation between HVS on FLAIR and hypointense vessels on SWI, and to determine whether these imaging features provide independent prognostic information in patients with ischemic stroke. METHODS We retrospectively analyzed consecutive ischemic stroke patients with proximal middle cerebral artery (MCA) occlusion who underwent SWI and FLAIR within 24 h of symptom onset. The presence of hypointense vessels on SWI and hyperintense vessels on FLAIR in >4 of 10 slices encompassing the MCA territory were considered to represent prominent hypoperfusion. RESULTS Among 50 patients, 62% had a prominent HVS on FLAIR and 68% had prominent hypointense vessels on SWI. There was a moderate but significant correlation between the number of slices with HVS on FLAIR and prominent hypointense vessels on SWI (r=0.425, P = 0.002). In multivariate analyses, the prominence of hypointense vessels on SWI, but not HVS on FLAIR, was significantly associated with a higher discharge NIHSS score (P = 0.027), mRS score (P = 0.021), and lesion growth (P = 0.050). CONCLUSION The significant, albeit moderate, correlation between markers of compromised tissue perfusion on FLAIR and SWI suggests that these imaging features reflect different but interrelated aspects of cerebral hemodynamics during ischemic stroke. Our findings highlight that while HVS on FLAIR denotes the presence of leptomeningeal collaterals, hypointense vessels on SWI signify the sufficiency of cerebral blood flow at the tissue level and are therefore more critical in terms of prognosis.WoSScopu

Congenital Mirror Movements In Gorlin Syndrome: A Case Report With Dti And Functional Mri Features

Congenital mirror movements are rare conditions that define the inability to perform unimanual movements. Gorlin syndrome, also known as nevoid basal cell carcinoma syndrome, is a genetic disorder with multiple nevi predisposing to basal cell carcinoma, odontogenic keratocysts, and skeletal malformations. Herein we report on an adolescent patient with Gorlin syndrome and coexisting congenital mirror movements. To our knowledge, this is the first patient in the literature who has both of these very rare conditions.WoSScopu

The Association of Cognitive Impairment with Gray Matter Atrophy and Cortical Lesion Load in Clinically Isolated Syndrome

Background: Multiple sclerosis can impair cognition from the early stages and has been shown to be associated with gray matter damage in addition to white matter pathology. Objectives: To investigate the profile of cognitive impairment in clinically isolated syndrome (CIS), and the contribution of cortical inflammation, cortical and deep gray matter atrophy, and white matter lesions to cognitive decline. Methods: Thirty patients with clinically isolated syndrome and twenty demographically-matched healthy controls underwent neuropsychologic assessment through the Rao Brief Repeatable Battery, and brain magnetic resonance imaging with double inversion recovery using a 3T scanner. Results: Patients with clinically isolated syndrome performed significantly worse than healthy controls on tests that evaluated verbal memory, visuospatial learning and memory, and verbal fluency. Significant deep gray matter atrophy was found in the patients but cortical volume was not lower than the controls. Visual memory tests correlated with the volume of the hippocampus, cerebral white matter and deep gray matter structures and with cerebellar cortical atrophy. Cortical or white matter lesion load did not affect cognitive test results. Conclusion: In our patients with CIS, it was shown that cognitive impairment was mainly related to cerebral white matter, cerebellar cortical and deep gray matter atrophy, but not with cortical inflammation, at least in the early stage of disease.

Congenital mirror movements in a patient with alpha-dystroglycanopathy due to a novel POMK mutation

Dystroglycanopathies are a heterogeneous group of muscular dystrophies often associated with variable brain and eye involvement. Glycosylated alpha-dystroglycan (ADG) plays a key role in the development and stability of basement membranes as well as organizing axon guidance in the central nervous system. Congenital mirror movements, either isolated or in association with several genetic syndromes, are defined as inability to perform unimanual movements. We report an adolescent boy with limb-girdle muscular dystrophy due to ADG deficiency and coexisting congenital mirror movements. Genetic work-up revealed a novel homozygous missense mutation in the protein O-inannose kinase (POMK) gene. To our knowledge, this is the first patient in the literature with POMK mutation and congenital mirror movements. (C) 2016 Elsevier B.V. All rights reserved
