A 25-year-old primigravida with a history of pre-eclampsia was brought to the emergency department with sudden onset of severe headache. The headache started two days after delivery. It was followed by confusion and loss of consciousness over a few hours. On initial evaluation, the patient was confused with a Glasgow Coma Scale (GCS) of 12/15, blood pressure of 130/90 mmHg, pulse rate of 82 beats/min, respiratory rate of 30/min, temperature 98°C, and oxygen saturation of 97 mmHg at room temperature. On physical examination, bilateral equivocal planters were noted with no other significant findings, and bilateral papillary edema on fundoscopy was seen. The rest of the review system was unremarkable. She underwent an urgent MRI with magnetic resonance venography (MRV) of the brain, which showed right transverse sinus thrombosis with an element of SAH (Figure ).\nCoagulation profile, including thrombin time (TT), prothrombin time (PT), partial thromboplastin time (PTT), antithrombin III, fibrinogen, proteins C and S, antiphospholipid antibody titers, and homocysteine levels, were normal. She was started on a half dosage of low molecular weight heparin (LMWH) (60 mg subcutaneously once a day) with regular monitoring of her blood pressure and GCS. Her GCS started improving; therefore, she was continued on a half dose of LMWH for 10 days, and brain MRI was repeated after 10 days, which showed the gradual resolution of SAH (Figure ). The quantity of LMWH was doubled, and warfarin was started after a full dose of LMWH. After improving her GCS and achievement of international normalized ratio (INR) of two to three, she was discharged with the advice of regular INR monitoring and follow-up to the outpatient department. On follow-up at six weeks, MRI with MRV was repeated, which showed thrombosis had resolved, although a mild filling defect was noted. She was kept on anticoagulants for one year, and on further follow-up at six months, she was doing well.
A 38-year-old woman on oral contraceptives presented with headache and difficulty speaking. She had no other significant past medical history. A left frontal SDH and left temporal venous infarct with a left transverse sinus thrombosis was demonstrated on CT and MRI []. A hypercoagulable work-up did not reveal any additional thrombophilias. She was initially managed with systemic anticoagulation using intravenous heparin. After serial neurologic examinations and repeat CT, head imaging demonstrated no further bleeding; she was transitioned to oral warfarin and discharged home. She had excellent neurologic recovery (modified Rankin score 0) at 3 months follow up visit.
