Originally reported as a respiratory
disease, but with more understanding of the condition, systemic components have
been fairly described. Features could be mild, moderate and severe. SARS-CoV-2
has been reported to bind ACE 2 receptors which ultimately results and in an
eventual ARDS due to increased pulmonary surface tension.
Radiologic features are essential of the
chest and serve as surrogate diagnostic markers and for prognostication.
Computed tomography (CT) is the radiological test. Conventional X-ray on the
other hand is less sensitive and specific compared to the former but usually,
it is the first-line imaging modality used for suspected Covid-19 cases.
Findings may be normal in early or mild disease severe cases show abnormal
signs which may be categorized as probable/classic, intermediate for Covid-19,
non-Covid-19, or normal (note that normal does not exclude Covid-19). These
abnormalities are usually bilateral, involving the lower lobes with predominant
air space opacification, interstitial infiltrates, or patchy consolidation.
