The first case of coronavirus disease 2019 (COVID-19) was declared in December in Wuhan, before becoming a global pandemic in a few weeks. Several complications of this infection have been reported. However, a spontaneous pneumomediastinum has rarely been described. We report the fourth case of this extremely rare complication in a 65-year-old male patient with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) pneumonia, discovered during his therapeutic management by a CT scan control.
Pneumopericardium is a rare complication of a blunt thoracic trauma. It is defined as the presence of air in the pericardial sac. There are just a few cases described in the literature.
This article brings pneumopericardium to light, reinforcing the importance of considering it within the blunt chest trauma and remarking its management with a careful monitoring for the patients whose stable or even asymptomatic with spontaneous ventilation because of the risk of tension pneumopericardium and cardiac arrest.
Diagnosis is often difficult, and it can be life-threatening by the occurrence of gas tamponade.
We report the case of a 48 years old patient victim of a severe traumatism with pneumothorax and pneumopericardium; he was stable with spontaneous ventilation.
Parathyroid carcinoma is a very rare malignant tumor of the parathyroid gland. This cancer poses a great diagnostic and therapeutic difficulty due to its rarity and the absence of a characteristic clinical and paraclinical picture. The diagnosis is histological but is not always easy. Surgery remains the only curative treatment, and cervical radiotherapy can be discussed. Good prognostic factors are complete monobloc tumor resection, and bad prognostic factors are the presence of lymph node metastases at diagnosis, distant metastases, and nonsecreting carcinomas.
Posterior reversible encephalopathy (PRES) is a rare but a serious disease that affects the central nervous system. PRES is responsible for various but nonspecific neurological symptoms, including confusion, coma, and seizures as well as visual disturbances. Diagnosis is made using cerebral MRI which typically shows at the early stage, bilateral symmetrical parietooccipital hyperintensities on T2 and fluid-attenuated inversion recovery (FLAIR) sequences. Case study. In this article, we base our research on a case study that includes, as a population sample, a 9-year-old boy who suffers from an acute postinfectious glomerulonephritis and arterial hypertension. Two days before diagnosis, he developed confusion with generalized tonic-clonic attacks. His blood pressure was 180/80 mmHg. A cerebral computed tomography made in emergency showed cerebral edema. It was supplemented by magnetic resonance imaging which revealed cortical and posterior cortical lesions which appear as hypointense on T1 and hyperintense on T2 and Flair. An MRI control was performed 40 days later which shows a clear improvement of the occipital lesions. PRES is a radioclinical syndrome characterized by the association of variable neurological signs which reversibility is conditioned by the early diagnosis and the correction of the contributing factors.
