Cerebral Venous Thrombosis, an Extremely Rare Complication of Iron Deficiency Anemia
INTRODUCTION: Cerebral venous thrombosis (CVT) is a rare type of stroke and can be challenging to diagnose. It is seen in most commonly young females and has been linked to thrombophilia, pregnancy, and contraceptive pills. Here we present a rare case of CVT in a young female with iron deficiency anemia.
CASE REPORT: A 19-year-old female patient presented with severe headache, CT scan of the head on admission showed acute superior sagittal sinus thrombosis which was confirmed with CT venogram and MRI of the brain. The patient had intact neurologic exam upon admission. She was started on heparin and admitted for monitoring. Later on she developed expressive aphasia and right sided weakness. She ultimately underwent catheter directed thrombolysis. Follow up CT and MRI scans showed significant decrease in clot burden, and the patient’s neurologic function started to improve.
Her initial labs were significant for thrombocytosis with platelet count 840,000/μL, and microcytic anemia with hemoglobin 9.6 g/dL and MCV 79 fL. She had low serum ferritin and iron levels with high total iron binding capacity consistent with iron deficiency anemia. An extensive hypercoagulable work up was done including antithrombin, protein C and S, factor V Leiden mutation, prothrombin gene mutation, hyperhomocysteinemia, antiphospholipid antibodies, anti-nuclear antibodies which all came back negative. Given her high platelet count, a myeloproliferative disorder was entertained however testing of mutations JAK2V617F, CALR, MPL, and BCR-ABL was negative. She also had a bone marrow biopsy that revealed normal bone marrow. The patient had no prior personal or family history of venous thrombosis, she was not taking any hormonal mediation and pregnancy test was negative. She did report menorrhagia for couple of months prior to admission.
CONCLUSION: After ruling out genetic prothrombotic states, autoimmune disease, and bone marrow disorders. We determined this was a case of cerebral venous thrombosis secondary to reactive thrombocytosis in setting of untreated iron deficiency and menorrhagia. The patient was started on iron supplements with improvement in her iron and hemoglobin levels, and subsequent decrease in her platelet count to normal values. She continued anticoagulation with rivaroxaban for 3-6 months period.
