Abstract
Background
COVID 19 is associated with a hypercoagulable state with cytokine storm syndrome and thrombocytopenia leading to complications across various systems. COVID-19 infection, its treatment, resultant immunosuppression, and pre-existing comorbidities have made patients vulnerable to secondary infections
Methods
We systematically reviewed COVID-19 cases between Jan to May 2021 for pulmonary and extrapulmonary complications. Patients with recent COVID-19 vaccination and neurological symptoms were also included.

Results
Neurological complications: Neurological complications include ischemic and haemorrhagic strokes. Other complications are encephalopathy, encephalitis, Guillain-Barré syndrome, acute hemorrhagic necrotizing encephalopathy. Demyelination and radiculopathies are seen as post vaccination complications. Mucormycosis: Unprecedented high rate of invasive fungal sinusitis in association with COVID -19 is reported from the Indian subcontinent. This has a propensity for intra orbital and intracranial extension. COVID -19 associated coagulopathy: COVID -19 is a pro-inflammatory hypercoagulable state. Pulmonary thromboembolism, deep venous thrombosis and catheter related thrombosis are well documented. Cardiac complications: Cardiac manifestations include Myocardial Injury with non-obstructed coronary arteries (MINOCA), myocarditis, myocardial ischemia, cardiomyopathy. Pulmonary complications and sequelae of COVID -19: Progression of lung injury to ARDS during the initial phase and fibrosis of parenchyma in the recovery phase. Spontaneous pneumomediastinum, pneumatoceles and pneumothorax and secondary infections are identified in our study. COVID- 19 associated gastrointestinal complications: Patients evaluated for renal colic, pancreatitis, cholecystitis showed, ground glass opacities or subpleural bands in typical Covid-19 distribution. COVID-19 may lead of acute kidney and bowel injury due to arterial thrombosis. COVID - 19 associated myonecrosis: Ischemia of the small caliber vessels may result in myonecrosis.

Conclusion
Awareness of these unusual manifestations will facilitate an early diagnosis, improve management and help reduce morbidity and mortality
