Abstract: | A case of cortical vein thrombosis presenting as intracranial haemorrhage is described in a patient with ovarian hyperstimulation syndrome (OHSS) after IVF and embryo transfer. Veno-occlusive disease of the brain could appear as a haemorrhagic lesion on magnetic resonance imaging (MRI) and this made the initial diagnosis of cortical vein thrombosis difficult. The patient developed deep vein thrombosis 2 weeks after the intracranial event and the diagnosis of cortical vein thrombosis was made at that time on MRI study after the resolution of the haemorrhage. This patient actually developed generalized thrombosis as a complication to OHSS. Although the initial MRI picture may be misleading, the diagnosis of thrombosis should always be kept in mind, as it is the commonest cause of intracranial lesions after OHSS. |
