RESUMO
A 23-year-old East Indian woman with no significant medical history, except a depot-norethisterone enanthate injection taken 3 weeks prior to admission, presented with a gradually worsening headache for the past 5 days. She had no fever, vomiting, neck stiffness, focal weakness or rash, and examination was unremarkable with no focal neurological deficits. Vasculitic, thrombophilia and sepsis screens were normal. A brain CT scan showed a left parietal lobe venous infarct, secondary to a venous dural sinus thrombosis, with MRI and Magnetic Resonance Venogram (MRV) confirming a signal void. She was diagnosed to have multiple cerebral venous sinus thrombosis due to norethisterone enanthate. She made a complete recovery following treatment with mannitol, dexamethasone and anticoagulants. A follow-up brain MRI done at 6 months was normal.

Two cases of cerebral venous thrombosis are reported. Patients were apparently healthy 39 and 28year old females with nonspecific presenting features. Image findings were characteristic of cerebral sinus thrombosis. The younger patient received progesterone to treat placental abruption eight years previously; she had cerebral venous thrombosis while using oral contraception. Both patients had used contraceptive pills for a long time. Oral hormonal contraceptives may increase the risk of vascular events, even in people without personal or family history of venous thrombosis. Modern imaging methods have contributed to early diagnosis, but the possibility of under diagnosis still persists. This report aims to increase the awareness of healthworkers about cerebral venous thrombosis in women, an entity often misdiagnosed, under diagnosed and underreported.
Se informan dos casos de trombosis venosa cerebral. Las pacientes eran mujeres aparentemente saludables, 39 y 28años de edad, con presentación clínica nonespecífica. Los dados de exámenes de imagen eran característicos de trombosis del seno cerebral. La paciente más joven recibió progesterona para tratar desprendimiento de placenta, y ocho años antes había presentado trombosis venosa cerebral mientras usando anticoncepción oral. Ambas pacientes habían usado las píldoras anticoncepcionales durante mucho tiempo. Los contraceptivos hormonales orales pueden aumentar el riesgo de eventos vasculares, incluso en las personas sin antecedente personal o familiar de trombosis venosa. Las nuevas técnicas de imágenes han contribuido al diagnóstico temprano, pero la posibilidad de diagnóstico insospechado todavía persiste. El propósito de este informe es aumentar el índice de sospecha de profesionales de la salud sobre la trombosis venosa cerebral en mujeres, entidad a menudo erróneamente diagnosticada, infradiagnosticada y no reportada.
