Herniation of uncus and parahippocampal gyrus: an accidental finding on magnetic resonance imaging of cerebrum.

Acta Radiol Short Rep 2015 Jan 6;4(1):2047981614560077. Epub 2015 Jan 6.

Department of Radiology, Aalborg University Hospital, Aalborg, Denmark.

Idiopathic herniation of uncus and parahippocampal gyrus into the ambient cistern is a very rare entity, which could be mistaken for other pathology such as tumor. To the best of our knowledge, two prior cases of this kind of herniation have been described. One of these cases was with associated symptomatology and other abnormalities, and the other was characterized as idiopathic. Read More

Intravenous thrombolysis in acute ischemic stroke patients with negative CT perfusion: a case series.

Acta Radiol Short Rep 2014 Aug 18;3(7):2047981614543219. Epub 2014 Aug 18.

Department of Surgery, Division of Neurosurgery, St. John Providence Health System, Detroit, MI, USA.

Background: Computed tomography perfusion (CTP) is a commonly used modality of neurophysiologic imaging to aid the selection of acute ischemic stroke patients for neuroendovascular intervention by identifying the presence of penumbra versus infarcted brain tissue. However many patients present with evidence of cerebral ischemia with normal CTP, and in that case, should intravenous thrombolytics be given?

Purpose: To demonstrate if tissue-type plasminogen activator (tPA)-eligible stroke patients without perfusion defects demonstrated on CTP would benefit from administration of intravenous thrombolytics.

Material And Methods: We retrospectively identified patients presenting with acute ischemic symptoms who received intravenous tPA (IV-tPA) from January to June 2012 without a perfusion defect on CTP. Read More

Department of Clinical Radiology, Ludwig Maximilians-University, Munich, Germany ; Department of Radiology and Nuclear Medicine, University Basel, Switzerland.

Sarcoidosis is a granulomatous disease, in which liver affection is common, contrary to a primary hepatic lymphoma that is very rarely seen. On MRI both present with almost the same imaging features: hypointense in T1-weighted and hyperintense in T2-weighted sequences. Our patient with a histologically confirmed sarcoidosis in the lungs showed liver lesions that were similar to sarcoidosis manifestations of the liver. Read More

Rare diagnosis of nodular lymphangitis caused by Mycobacterium marinum: MDCT imaging findings.

Acta Radiol Short Rep 2014 Feb 21;3(2):2047981614523172. Epub 2014 Feb 21.

Department of Radiology, Hospital Clinic, Universidad de Barcelona, Barcelona, Spain.

Mycobacterium marinum is an atypical mycobacterium that usually causes a solitary nodule on the hand ("fish tank granuloma") or less commonly, secondary erythematous channels and nodules spread along lymphatic drainage of the extremity, mimicking sporothricoid skin lesions of nodular lymphangitis. This report presents a case of this rare entity, a nodular lymphangitis caused by Mycobacterium marinum. Multidetector computed tomography (MDCT) imaging was very useful in determining the morphology (cellulitis with a few small subcutaneous nodules and channels) and the extension of the lesion.

Imaging findings in uncorrected tetralogy of Fallot and pulmonary atresia with major aortopulmonary collateral arteries and septic embolism.

Acta Radiol Short Rep 2014 Jan 3;3(1):2047981613515211. Epub 2014 Jan 3.

Department of Interventional, Pediatric and Diagnostic Radiology, Inselspital, University Hospital, University of Bern, Bern, Switzerland.

Tetralogy of Fallot (TOF) is one of the most common congenital heart malformations comprising a ventricular septal defect, right ventricular outflow tract obstruction, right ventricular hypertrophy, and overriding aorta. A rare variant includes pulmonary atresia and major aortopulmonary collateral arteries. Altered hemodynamics within the functional single-ventricle results in turbulent flow and predisposes to endocardial vegetation formation which may consequently lead to thromboembolic events.
