Radiological manifestations and complications of lung and brain in Egyptian COVID-19 patients

BACKGROUND: Coronavirus disease COVID-19 is a viral illness, currently affecting millions of people worldwide. Pneumonia is the most common extreme presentation of COVID-19 infection, manifesting by fever, dry cough, difficulty of breathing or shortness of breath and mainly ground-glass infiltrates in radiological images. Chest computed tomography (CT) has a potential role in the diagnosis, detection of complications and prognostication of coronavirus disease COVID-19. In addition to severe respiratory manifestations, there are a wide range of neurological manifestations ranging from nonspecific symptoms to necrotizing encephalopathies and stroke. Our study aimed to review lung and neurological manifestations in recent and post-COVID-19 Egyptian patients and to be familiar with magnetic resonance imaging (MRI) findings of Neuro-COVID patients. RESULTS: The present study included eighty COVID-19 patients with age ranged from 28 to 78 years (mean age 57.84 + 12.58 years) who were 54 males (mean age 56.64 + 12.50) and 26 females (mean age 48.65 + 14.24). All our patients were with recent or previous history of COVID-19 infection and subjected to careful history taking, thorough clinical examination, routine laboratory investigations and CT examination. The reported lung manifestations included normal lung shadows, ground-glass opacifications (GGOs), consolidations, reticulation, reticulation and GGOs (crazy paving) and fibrotic-like changes. Out of eighty COVID-19 patients, twenty showed neurological manifestations ranging from nonspecific symptoms to necrotizing encephalopathies and stroke. Patients with neurological manifestation were in addition to CT submitted to magnetic resonance imaging (MRI) as appropriate. MRI done to neuro-COVID patients showed that 8/20 (40%) had no abnormalities and 12/20 (60%) had abnormalities. The most common abnormalities are infarction, major or lacunar infarction, followed by acute disseminated encephalomyelitis (ADEM), posterior reversible encephalopathy syndrome (PRES) and meningoencephalitis. CONCLUSION: Old age patients, especially males, were more affected than females. Lung manifestations are common in COVID-19 patients than neurological manifestations. The presence of fibrotic changes in the lung could predict severe COVID-19 affection and bad prognosis. There might be an association between appearance of neurological manifestations and poor outcome in COVID-19 patients.
