Hemorrhagic PRES: A Rare Neurological Manifestation of COVID -19 Infection.

As of August 2021, the COVID -19 pandemic has affected approximately 200 million cases worldwide. Most of the reported medical literature about the COVID-19 infection discusses its respiratory and haematological manifestations, with limited information about its neurological complications. Encephalitis, meningitis, acute disseminated encephalomyelitis, stroke and encephalopathy have been reported in patients with COVID-19 infection.

Rhino-orbito-cerebral Mucormycosis: Pictorial Review.

Mucormycosis (MCR) is a fulminant, potentially lethal, opportunistic fungal infection. Diabetes, immunocompromised states and elevated serum iron levels are the most important risk factors for contracting MCR infection. Recently, MCR co-infections have been observed in patients with COVID-19 disease owing to a complex interplay of metabolic factors and corticosteroid therapy.

Imaging in Sinonasal Inflammatory Disease.

While most patients with inflammatory rhinosinusitis are successfully diagnosed clinically, imaging is indicated in patients with recurrent or chronic sinusitis, atypical symptoms and complicated acute sinusitis. Non-enhanced high resolution, thin section computed tomography (CT) is the reference standard in evaluating such patients. It provides superb anatomical details and enables a fairly accurate diagnosis and delineation of the disease, addressing all concerns of the endoscopic surgeon prior to intervention.
