“…The laboratory findings of that study revealed thrombocytopenia, low fibrinogen levels and elevated D-dimer levels, while antibodies against platelet factor 4 were positive in the majority of assays performed ( 2 ). However, it should be noted that sometimes, in certain age groups of patients, these symptoms may be associated with congenital vascular anomalies or drug abuse ( 3 , 4 ). Carbon monoxide, viper envenomation, methylenedioxymethamphetamine have been reported to lead to acute cerebral venous thrombosis ( 5-7 ).…”

The present study describes the case of a 25-year-old male patient who presented to the emergency department with severe headache and vertigo lasting for 3 days. The patient did not have a recent history of trauma. He was vaccinated with a second dose of the AstraZeneca COVID-19 vaccine ~1 month prior, and he suffered from a vitamin B12 deficiency due to nitrous oxide abuse. Upon an examination of his vital signs, he was found to have a body temperature of 36.4˚C, a pulse rate of 64 beats per minute, a respiratory rate of 18 breaths per minute and a blood pressure of 119/68 mmHg. A neurological examination only revealed left homonymous upper quadrantanopia. The serum platelet count of the patient was 361x1,000/µl and he had elevated D-dimer levels (0.98 µg/ml). A provisional clinical diagnosis of acute cerebrovascular accident was made. A computed tomography scan of the head revealed an abnormal hyperattenuation in the straight sinus and bilateral transverse sinuses. A diagnosis of cerebral sinovenous thrombosis (CSVT) was made following a consultation with a neurologist. The patient was treated with enoxaparin at 6,000 IU, levetiracetam at 1,000 mg and mannitol at 100 ml via an intravenous drip. After admission, magnetic resonance venography revealed the absence of flow in the straight sinus and bilateral transverse sinuses. A thrombophilic investigation revealed a plasma homocysteine level of 59.03 µmol/l (upper normal limit, 15.39 µmol/l), a vitamin B12 level of <148 (lower normal limit, 187 pg/ml). CSVT secondary to homocystinemia was diagnosed. The treatment included anticoagulation and vitamin B12 supplementation. The patient was administered vitamin B12 at 500 mcg twice per day, pyridoxine at 50 mg per day, folic acid at 5 mg two times per day and edoxaban at 60 mg per day. After 7 days of treatment, his headache and quadrantanopia were improved, and the patient was discharged.

Subarachnoid hemorrhage is a neurological emergency in which arterial blood accumulates in the subarachnoid space with cerebral aneurysmal rupture being the most common cause. Subarachnoid hemorrhage is often misdiagnosed in the emergency department and mortality rates range from 8% to 67%. It may be the manifestation of the chronicity of the migraine. The difference in severity or quality compared to previous headaches, and other symptoms, particularly neck stiffness, but also seizure, syncope, focal neurological deficit, and vomiting are the key factors differentiating subarachnoid hemorrhage from the migraine. We report a case of a 37-year-old female with a previous history of migraines who presented with acute onset of excruciating headaches in the occiput associated with nausea, vomiting, and photophobia in whom a non-contrast computed tomography scan of the head showed hyper-densities involving the bilateral cerebral cortical sulcus and Sylvian fissure and the cerebral angiography showed a complex aneurysm in anterior communicating artery.
