Computed tomography aspect of primary lung cancer

Background: Primary lung cancer (PLC) is the world’s leading cancer in terms of incidence and mortality. The objective of our study is to identify morphological criteria by scanning towards a histological type of PLCs. Methods: This is a retrospective transversal analytical study, carried out at the oncology, radiotherapy and clinical haematology department of Joseph Ravoahangy Andrianavalona teaching hospital, from January 01, 2014 to December 31, 2018, covering all new histologically proven cases of PLC. The parameters of the study were epidemiological, CT scan and anatomopathological data. Results: We collected 95 cases. The average age was 59.11 years. The male gender was the most affected with a sex ratio of 1.8. The most common clinical call sign was chronic cough with 74.74% of cases. The radiographic appearance was parenchymal opacity in 54.5% of cases. Adenocarcinoma had the predominant histological type with 45.26% of cases associations were found between histological type and tumor site (p=0.0001), intratumor excavation (p=0.0001), intratumor necrosis (p=0.012). Conclusions: Morphological appearance of CT scan lesions may approach histological type of PLCs

Surdité bilatérale révélant une sidérose superficielle du système nerveux central : une observation clinique: Bilateral hearing loss revealing a superficial siderosis of the central nervous system: a clinical case report

Superficial siderosis of the central nervous system is a rare pathology due to a chronic subarachnoidhemorrhage involving deposits of hemosiderin on the surface of the brain, the cranial nerves and the spinal cord. It causes the progressive appearance of symptoms of which the most classic associate hearingloss, cerebellar ataxia and pyramidal syndrome. We report a case of a 43-year-old man presenting a bilateral hearingloss of progressive worsening. Radiological exploration allowed the diagnosis of superficial siderosis of the central nervous system. La sidérose superficielle du système nerveux central est une pathologie rare liée à une hémorragie sous-arachnoïdienne chronique entrainant des dépôts d’hémosidérine à la surfacedu cerveau, des nerfs crâniens et de la moelle épinière. Elle entraine l’apparition progressive des symptômes dont la plus classique associe la surdité, l’ataxie cérébelleuse et le syndrome pyramidal. Nous rapportons le cas d’un homme de 43 ans, présentant une surdité bilatérale d’aggravation progressive dont l’exploration radiologique a permis de poser le diagnostic de sidérose superficielle du système nerveuxcentral

Tableau clinique de colique néphrétique révélant une malformation vasculaire rénale: Clinical presentation of renal colic revealing a renal vascular malformation

Renal arteriovenous malformation is a rare embryonary’s dysplasia We report the case of a 44-year-old woman, who presented left-sided renal colic Uroscanner did not show any obstructive syndrome of urinary tracts associated with either lithiasis or tumoral syndrome However, it revealed a left renal arteriovenous malformation. La malformation artério-veineuse rénale est une dysplasie d’origine embryonnaire rare Nous rapportons le cas d’une femme de 44 ans, qui a présenté un tableau clinique de colique néphrétique gauche L’uroscanner ne révélait pas de syndrome obstructif des voies urinaires ni de lithiase ni de syndrome tumoral Par contre, il a montré une malformation artério-veineuse rénale à gauche

Atypical alveolar proteinosis

Alveolar proteinosis is a rare pulmonary disease characterized by intra-alveolar accumulation of surfactant composed of lipoproteinaceous material, related to a lack of surfactant resorption by alveolar macrophages. Crazy paving pattern is characteristic, but not specific. The multinodular forms of this affection remain exceptional
