RESUMO
We describe a case of a man aged 41 years who presented with a history of generalised headaches for 1 week and an acute episode of tonic-clonic seizures. He had no history of medical illness, was non-smoker, with an extensive family history of haematological disorders. Initial CT brain with contrast did not show any abnormalities in brain parenchyma. X-ray and CT right shoulder showed shoulder dislocation secondary to trauma associated with seizure prior to hospital admission. Subsequently, MRA and MRV brain was arranged, which revealed extensive expansible occlusive filling defect dominating the middle of superior sagittal sinus with left frontal cortical and subcortical acute oedema. He was promptly started on anticoagulation therapy. Considering the unusual site and unprovoked nature of thrombosis, further investigations including JAK2 mutation were arranged which revealed latent myeloproliferative disorder. He was referred to haematology services for further follow-up and monitoring of latent myeloproliferative disorder.

We describe a case of 52-year-old man who presented with an episode of tonic-clonic seizures. He had right ocular melanoma 23â years ago with subsequent enucleation which was the standard treatment at that time. CT scans of the brain and of the thorax-abdomen-pelvis revealed widespread metastatic lesions in the brain, lung and liver. Further investigations including bronchoscopy with cytopathology uncovered that the metastatic disease was a recurrence of ocular melanoma. He received palliative radiotherapy and died 6â months later. Ocular melanoma is often associated with fulminant metastatic disease after a period of dormancy. Thus, despite successful treatment of the localised disease at initial presentation, an effort is needed for optimal long-term follow-up plan in order to improve survival in case of recurrence.
