Affections du côlon en situation d’urgence et en réanimation chez le patient adulte : qu’attendre du radiologue ?

L’objectif de cet article est de donner un état des lieux des réponses actuelles du radiologue aux questions que les urgentistes et réanimateurs se posent dans leur vie quotidienne, lorsqu’une atteinte colique est suspectée chez un patient adulte. Les techniques radiologiques seront présentées, avec ce qu’elles peuvent apporter dans quelques situations cliniques usuelles telles qu’une colite infectieuse, une colite inflammatoire, une colite ischémique et les situations postopératoires intestinales, en particulier les déhiscences de sutureThe aim of this paper is to present an overview of the usefulness of imaging techniques for the management of acute disorders of the colon in adult patients. Contributions and limitations of the imaging techniques are presented, including infection, inflammation, ischemia, and post-operative complications of the colorectal surger

A Rare Complication of Appendicostomy.

TEACHING POINT: The acute appendicitis in a context of Malone appendicostomy complication is very rare but can occur and may be challenging to diagnose due to its unusual position

Retroperitoneal Lympathic Malformations as First Presentation of Lymphangioleiomyomatosis.

This case highlights the extrapulmonary lymphatic abnormalities that may be associated with pulmonary lymphangioleiomyomatosis

Schwannoma: A Rare Cause of Perineal Pain

Teaching point: Unexplained persistent perineal pain poses a differential diagnosis, including pelvic nerve lesions. The rare occurrence of pelvic schwannoma is easily shown by a MRI as a T2-hyperintense enhancing mass

Right ventricle function assessment by MDCT.

OBJECTIVE: The right ventricle is often overlooked on chest and even cardiac MDCT studies. This article will review the normal anatomy of the right ventricle on MDCT and the signs of its functional alterations. CONCLUSION: MDCT signs of right ventricular dysfunction should be known and checked in relevant cases, such as pulmonary embolism in particular, and in any disease that affects both the structure and function of the lungs in general

Intestinal angioedema from ACE-inhibitor

A 41-year-old Congolese woman born in 1977 presented in February 2018 to our emergency department with severe abdominal pain. Her medical history was notable for idiopathic collapsing glomerulopathy for which she was being initially treated with corticosteroids, later switched to tacrolimus. Additionally she was on candesartan 16 mg/d, then later switched in 2014 to enalapril 20 mg/d. During 2017, she was poorly compliant with her medications. In February 2018, her medications included tacrolimus, furosemide, spironolactone, lercanidipine, and enalapril. [...

Virtual unenhanced phase with spectral dual-energy CT: Is it an alternative to conventional true unenhanced phase for abdominal tissues?

PURPOSE: To compare attenuation measurements and image quality of virtual unenhanced phase (VUP) images with those of conventional true unenhanced phase (TUP) images on spectral dual energy computed tomography (DECT) with dual layer detector on abdominal tissues and to assess potential reduction in radiation dose. MATERIAL AND METHOD: A total of 295 patients (185 men, 110 women; mean age 61±17.6 [SD] years [range: 17-95 years]) who had undergone abdominal or thoraco-abdominal CT with pre- and post-contrast imaging (portal phase) with spectral DECT with dual layer detector were retrospectively analyzed. VUP images based on portal-venous phase DECT acquisition were generated. Regions of interest were defined in abdominal tissues (liver, spleen, kidney, muscle and fat) by two independent readers. Inter-technique agreement (VUP images vs. TUP images) on attenuation measurements was assessed. Signal-to noise ratio (SNR) and image quality of TUP and VUP images were compared. The radiation dose delivered to patients was compared with the radiation dose of protocols without TUP images. RESULTS: A total of 9880 ROIs were drawn in the abdominal tissues. The difference in mean attenuation values between TUP and VUP images was less than 15 HU in 98.3% and less than 10 HU in 92.3% of all measurements. VUP images overestimated attenuation in fat comparatively to TUP images. Image quality was evaluated as good or excellent in 77% (37/48) of TUP images and 54% (26/48) of VUP images. Using VUP images instead of TUP images could decrease the radiation dose by 32%. CONCLUSION: VUP images demonstrate good agreement with TUP images in different abdominals tissues and can be obtained with similar image quality as TUP. VUP images appear as an alternative to TUP images, resulting in reduction of radiation dose delivered to the patient

Giant idiopathic ulcer of esophagus in the context of acquired immunodeficiency syndrome (AIDS).

The giant ulcer of esophagus is a rare entity in the context of human immunodeficiency syndrome. In front of this type of ulceration the radiologist must to distinguish between two types of ulcers HIV, cytomegalovirus (CMV). The differential diagnosis is necessary for orientation of the therapy and is the result of association between radiological, endoscopic and pathological findings
