Abstract

Chronic subdural hematoma (CSDH) typically develops in the supratentorial region in elderly patients. We treated a case of unilateral supratentorial and bilateral infratentorial CSDH, whereby the patient had a coronavirus disease 2019 (COVID-19) infection combined with disseminated intravascular coagulation 2 months earlier. The patient had not experienced any head trauma before the onset of the CSDH. The postoperative course was uneventful, and the patient experienced no neurological deficit. We propose that we should be aware not only of acute ischemic or hemorrhagic diseases after COVID-19 infection but also of chronic subdural hematoma caused by coagulopathy after a COVID-19 infection.

Introduction

Chronic subdural hematoma (CSDH) usually develops in the supratentorial region in elderly patients. Infratentorial CSDH is rare in adults.1-3) We treated a case of unilateral supratentorial and bilateral infratentorial adult CSDH, whereby the patient had been infected with coronavirus disease 2019 (COVID-19) 2 months earlier. A COVID-19 infection has been shown to induce acute ischemic stroke and intracranial hemorrhage due to coagulation disorders.4,5) For the first time, we report supratentorial and infratentorial CSDH due to disseminated intravascular coagulation (DIC) after a COVID-19 infection. We present the clinical course of our case and discuss a review of the literature.

Case Report

A 70-year-old female patient without head trauma had a high fever on day X. She was admitted to our hospital on day X + 15 due to respiratory distress resulting from a COVID-19 infection. She showed no neurological deficit, but a blood exam revealed DIC (Table 1). She was treated with remdesivir, dexamethasone, and heparin. Her symptoms and DIC were cured, and she was transferred to another hospital on day X + 28. The patient was discharged from the hospital on day X + 44. On day X + 55, she felt a headache that slowly increased in intensity. There had been no head trauma during the entire period of treatment. On day X + 62, her condition deteriorated and her right forehead was bruising. She was transferred to our emergency department with a disturbance of consciousness (Glasgow Coma Scale 8) with quadriplegia and with total aphasia. A blood examination did not reveal any coagulation disorder (Table 1). Computed tomography (CT) showed a right supratentorial CSDH and bilateral infratentorial CSDH (Fig. 1A, B). Evacuation and drainage of the supratentorial CSDH were done with a single burr hole under local anesthesia. The hematoma membrane was thickened, and its color was dark. She regained consciousness and had no neurological disturbance on the day after the surgery. CT and magnetic resonance imaging (MRI) showed a reduction of the right supratentorial CSDH, no change in the infratentorial CSDH, and no upper herniation (Fig. 1C, D, Fig. 2A, B). She was discharged 2 days after the surgery without any neurological deficit. One week after surgery, an MRI image showed that the bilateral infratentorial subdural hematoma had decreased, and the supratentorial and bilateral infratentorial CSDH were cured 1 month after the surgery (Fig. 2C-F).

Arrows 4, 5, and 6 show a decrease in the subdural hematoma in the right supratentorial region, and the subdural hematoma in the infratentorial region has not increased. Arrow 7 shows that a hematoma at the rostral surface of the tentorial region has not increased.

Arrows 1 and 2 show that the hematoma in the supratentorial and infratentorial regions has not increased. Arrows 3 and 4 show that a subdural hematoma in the supratentorial and infratentorial regions has decreased. Arrows 5 and 6 show that the subdural hematoma in the supratentorial and infratentorial regions is cured.

Discussion

This is the first case report that reveals supratentorial and infratentorial CSDH after a COVID-19 infection and an absence of head trauma.

We discovered several cases of unilateral or bilateral supratentorial CSDH after a COVID-19 infection (Table 2).6) Panciani PP et al. reported relatively poor outcomes for five cases of CSDH that were also being treated for COVID-19 and which included thrombocytopenia and/or anticoagulation therapy. Our case here presented CSDH after COVID-19 was cured; there have been no previous reports of CSDH after cure of a COVID-19 infection. The incidence of general hemorrhage after cure of a COVID-19 infection has been reported to be 0.7%-2.9%.7,8) Another report described DIC complicated with a COVID-19 infection as inducing significant general bleedings.9) We speculate that our present CSDH was produced by DIC complicated with a COVID-19 infection and/or anticoagulation therapy.

We know that CSDH of the posterior fossa is rare in an adult, especially in the supratentorial and infratentorial regions (Table 3).1-3),10-12) Those CSDH cases were caused by craniotomy,1) bleeding from the venous sinus due to trauma,13) anticoagulation therapy,10,11) or thrombocytopenia.14) Our case was complicated by DIC and received antithrombotic therapy and was therefore compatible with previous reports.

COVID-19 infection sometimes induces arterial and venous thrombosis along with an abnormality of coagulation markers and thrombosis.15-17) DIC has been shown to develop in 2% of patients with COVID-19, and thrombocytopenia, in 10.3% of patients with COVID-19.9) The International Society of Thrombosis and Haemostasis thus recommends using heparin for COVID-19-infected patients with coagulopathy.18) However, ischemic stroke has also been shown to develop in 1.2% of patients with COVID-19.15) We assume that more and more people who are treated with anticoagulation therapy, especially with DIC, will be diagnosed with CSDH without head trauma.

To conclude, we propose that we should be aware of not only acute ischemic disease and acute bleeding diseases but also CSDH after a COVID-19 infection treated with anticoagulation therapy, especially in the presence of DIC.
