We report the first case of Guillain-Barré syndrome (GBS) associated with SARS-CoV-2 infection in Japan. A 54-year-old woman developed neurological symptoms after SARS-CoV-2 infection. We tested for various antiganglioside antibodies, that had not been investigated in previous cases. ⋯ In previous reports, most patients with SARS-CoV-2-infection-related GBS had lower limb predominant symptoms, and antiganglioside antibody tests were negative. Our findings support the notion that non-immune abnormalities such as hyperinflammation following cytokine storms and microvascular disorders due to vascular endothelial damage may lead to neurological symptoms in patients with SARS-CoV-2 infection. Our case further highlights the need for careful diagnosis in suspected cases of GBS associated with SARS-CoV-2 infection.

Case Reports
Long-term use and remission of granulomatosis with polyangiitis with the oral C5a receptor inhibitor avacopan.
Granulomatosis with polyangiitis (GPA) is a rare antineutrophil cytoplasm antibody-associated vasculitis. Several therapeutic advances have occurred over the past two decades, but relapse rate remains high and refractory cases are not uncommon. ⋯ The patient was able to successfully reduce her glucocorticoid dose and reduce her immunosuppressive treatments without another flare. She has been on avacopan for 35 months, had no adverse events that required its discontinuation, and her disease is in sustained remission.

An 18-year-old man presented with persistent isolated headache 2 weeks after recovering from acute COVID-19 illness. Extensive cerebral venous sinus thrombosis (CVST) was detected on CT venogram despite him having no other thrombotic risk factors. CVST can complicate COVID-19. A high index of clinical suspicion is warranted as it can often have a subtle presentation with paucity of neurological symptoms.

A 60-year-old woman was investigated for abdominal pain and increasing asthenia. Abdominal CT revealed a 25 mm hypodense cystic lesion in the tail of the pancreas. MRI showed a multiloculated cystic lesion, T1-hypointense and T2-hyperintense lesion, without wall enhancement. ⋯ Histologically, the cyst was multiloculated, lined by cuboidal epithelium, ovoid nuclei and amphophilic cytoplasm, without mucin deposition or cytological atypia. Immunohistochemistry examination revealed positive staining for cytokeratin 5/6, vimentin and calretinin. At 1-year follow-up, she is in her usual health, without any symptoms.

Case Reports
Case of COVID-19 infection and polycythaemia presenting with massive acute pulmonary embolism.
We are reporting a middle-aged male patient with polycythaemia vera comorbidity. The patient was exhibiting symptoms including fever, cough and shortness of breath and was found to have acute pulmonary embolism. He was diagnosed with SARS-CoV-2. This case suggests that a high index of suspicion should be taken into consideration for thromboembolic events, when treating patients with COVID-19 with breathing difficulty and low oxygen saturation levels, especially in those who have underlying predisposing conditions for coagulopathy.
