ABSTRACT
We present a case of a 20 years old woman who consults for amenorrhea and mild hyperprolactinemia. Within the functional study hypopituitarism was discover and MRI showed a cystic lesion with ring enhancement. Transsphenoidal resection was performed, showing purulent material. Cultures were positive for MSSA and Neisseria cinerea. Antibiotic treatment was started completing 21 days. She evolved without relapse but did not recovered pituitary function.

Los aneurismas de la arteria espinal posterior (AEP) se presentan en su gran mayoría asociados a patologías que generan aumento del flujo arterial como malformaciones o fístula arteriovenosas y también asociadas a enfermedades del colágeno. Su presentación aislada es rara, con 11 casos publicados en la literatura a nuestro conocimiento. Presentamos una paciente de 56 años de edad, usuaria de anticoagulantes orales por accidente cerebro vascular antiguo no secuelado secundario a fibrilación auricular, que se presenta con dolor lumbar súbito no irradiado, al que luego se agrega paraplejia fláccida. En resonancia nuclear magnética se observa hemorragia subaracnoidea espinal con importante compresión medular secundaria. Estudio con angiografía demostró aneursima de aspecto disecante en arteria espinal posterior. Debido a pequeño calibre de arteria nutricia se optó por tratamiento quirúrgico. Angiografia de control mostró exclusión completa de aneurisma. En los controles posteriores la paciente ha mostrado recuperación progresiva del déficit neurológico. Tanto el tratamiento endovascular como el quirúrgico se han reportado para la exclusión de aneurismas de la AEP. El presente caso muestra que el tratamiento quirúrgico precoz es una alternativa sobre todo si además se requiere realizar descompresión medular.
Aneurysms of the Posterior spinal artery (PSA) usually present secondary to high-flow pathologies such as arteriovenous malformations or dural arteriovenous fistulas, also can be associated whit collagen diseases. Isolate PSA aneurysms are rare, whit 11 cases reported, to our knowledge. We present a 56 years old patient, user of oral anticoagulant for an old isquemic stroke, secondary to atrial fibrillation, who presented whit subit lumbar pain and flaccid paraplejia. The magnetic resonance image shows an extensive spinal subarachnoid hemorrhage and secondary medular compression. Spinal angiography study demonstrated a dissecting aneurysm of PSA. Due to the small size of the artery, on which the aneurysm was located, surgical treatment was performed. Follow up angiography shows complete exclusion of the lesion. The patient has had a progressive recovery on her deficit. Both surgical and endovascular treatment have been reported. The present case shows that early surgical treatment is an option, especially if medular decompression is needed.
