Tentorial dural arteriovenous fistula (DAVF) is an aggressive vascular lesion causing progressive neurological deficits. Venous congestive cervical edema is a rare phenomenon caused by tentorial DAVF. Obliteration of the fistula and venous drainage should be the goal of treatment. A 62-year-old man was admitted with lower limb weakness and numbness. Magnetic resonance imaging (MRI) revealed extensive edema of the upper cervical cord with signal flow void at the anterior spinal cord. Internal carotid angiography revealed a tentorial arteriovenous shunt near the superior petrosal sinus fed mainly by the tentorial artery. The petrosal vein was dilated, with the transverse pontine vein, medial medullary vein, and anterior spinal vein as the main drainage route. This suggests that venous hypertension triggered the upper cervical cord edema. MRI with gadolinium enhancement showed that the varix was located just distal to the shunt. Microsurgical obliteration of the fistula and venous drainage were achieved via a suboccipital approach. A postoperative evaluation showed the disappearance of the cervical cord edema with improved clinical symptoms. Tentorial DAVF with spinal venous drainage presents with mild and slow progression of symptoms. Differential diagnosis and definite treatment are mandatory to avoid a delayed diagnosis and irreversible symptoms.

Coronavirus disease 2019 (COVID-19) and influenza may infect a person simultaneously; hence, adequate measures must be prepared for the next winter in Japan. In preparation for the future, this study aimed to clarify the rate of influenza coinfection in patients with COVID-19 in previous winter. We conducted a retrospective study of the medical records of 193 patients diagnosed as having COVID-19 between January 31, 2020, and April 23, 2020, in a single hospital. We measured the rate of coinfection with COVID-19 and influenza. We found no patient was coinfected with influenza using rapid diagnostic testing. The occurrence of coinfection with influenza and COVID-19 seems to be rare in the past winter in Japan.
