[2] Ischemic stroke in COVID-19 patients is multi-causal and may be due to micro-/ macro-angiopathy, cardio-embolism, hypercoagulability, thrombocyte dysfunction, or arterial hypertension. We should be told which of these mechanisms was made responsible for hemorrhagic stroke of the macro-adenoma. A shortcoming of Fig. 1 is that only two MRI modalities (T1, T2) were provided. Since the patient was diagnosed with hemorrhagic stroke of the pituitary gland it is crucial to provide DWI, PWI, and SWI modalities and MR-angiography to assess if major cerebral arteries were properly perfused. Since steroids may promote cerebral bleeding and may prolong SARS-CoV-2 viremia, [3] we should be told why the patient received steroids although the diagnosis COVID-19 had been established already. Since acute visual loss is multi-causal and since therapy should start after establishing a diagnosis, it is crucial that cerebral imaging is carried out before starting steroids. Since steroids are not only beneficial but potentially harmful, the indication should be clear-cut. It should be explained why the patient did not undergo immediate neurosurgery. Since he experienced acute visual loss and steroids were only partially beneficial it would have been comprehensible to decompress the chiasma immediately. Obviously, the macro-adenoma became symptomatic due to swelling from SARS-CoV-2-associated apoplexy and bleeding. Missing are the outcome after neurosurgery and the long-term outcome of vision, particularly if it recovered completely or only partially. Overall, the interesting case has limitations that challenge the conclusions.
