Coronavirus disease 2019 (COVID-19) is an emerged pandemic disease caused by a new coronavirus known as SARS-CoV-2 (severe acute respiratory syndrome-coronavirus-2). Initially the mortality of this infection are related to severe acute respiratory distress syndrome, but several publications also showed that this infection caused an inflammatory response with severe systemic complications [1] . Venous thromboembolism has been shown to be an important cause of morbidity and mortality in patients with COVID-19, both in the general inpatient and in the intensive care unit (ICU) setting, and even in patients receiving therapeutic anticoagulation [2] . We report the case of an adult patient who presented a cavernous sinus thrombosis during his hospitalization for covid 19.

Wernicke’s encephalopathy is a rare disease, resulting from severe thiamine deficiency (vitamin B1). Alcoholic subjects are most often affected, but it may occur outside of this addiction. Magnetic resonance imaging is the gold standard imaging modality to confirm the diagnosis. This pathology manifests itself in T2-weighted hyperintensity in the periaqueducal, thalami and mammillary bodies. A suitable treatment makes it possible to avoid heavy sequelae. We report the case of a 23-year-old woman, pregnant with 12 weeks of amenorrhea, with diplopia, headache and abundant vomiting, reffering to Wernicke’s encephalopathy. Key words: Wernicke’s encephalopathy, vitamin B1, Magnetic resonance imaging, hyperemesis gravidarum.

L’agénésie unilatérale de l’artère pulmonaire est une malformation congénitale rare. Sa symptomatologie respiratoire est variable : infections respiratoires, gêne à l’effort, hémoptysie. Sur le plan radiologique, cette anomalie peut être évoquée  sur une radiographie thoracique standard mais doit être confirmée par angiographie.  Nous rapportons le cas d’une jeune patiente âgée de 27 ans, présentant une dyspnée stade III de NYHA.  Un angioscanner a été réalisé et a objectivé une agénésie de l’artère pulmonaire droite. La prise en charge de ces patients n’est pas encore consensuelle à ce jour et dépend de l’évolution clinique. Cependant il se limite le plus souvent à une surveillance clinique et paraclinique régulière afin de dépister d’éventuelles complications.
