Cirugía neurológica en meningioma del tercio medio del ala del esfenoides. Presentación de un caso / Neurological surgery in meningioma of the middle third of the wing of the sphenoid. Presentation of a case

RESUMEN Se presentó un caso de una paciente de 70 años de edad, con antecedentes patológicos personales de hipertensión arterial controlada, además de un síndrome demencial instaurado hace 5 años aproximadamente. Con un diagnóstico presuntivo de una demencia tipo Alzheimer y sin estudios desde el punto de vista imagenológico. Se le realizaron diversos estudios que arrojaron una lesión extraaxial interpretada como un meningioma del tercio medio del ala del esfenoides. Se le aplicó una resección tumoral de la totalidad de la lesión, su evolución postquirúrgica fue satisfactoria (AU).

ABSTRACT The case presented is the one of a female patient aged 70 years, with personal pathological antecedents of controlled arterial hypertension besides dementia syndrome for around five years, presumptively diagnosed as Alzheimer-kind dementia without imaging studies. She underwent several studies showing an extra axial lesion that was interpreted as meningioma of the medial third of the sphenoid wing. The tumor resection of the entire lesion was carried out; the post-surgery evaluation was satisfactory (AU).

Metaplastic Meningioma Overspreading the Cerebral Convexity.

Meningioma is relatively common, benign, and extra-axial tumor accounting for about 20% of primary brain and spinal cord tumors. The World Health Organization (WHO) classified these tumors into Grade I (benign), Grade II (atypical), and Grade III (anaplastic) meningioma. Grade I meningioma which is slowly growing tumor and have some rare subtypes. Among them, metaplastic subtype is defined as a tumor containing focal or widespread mesenchymal components including osseous, cartilaginous, lipomatous, myxoid or xanthomatous tissue, singly or in combinations. We report a rare metaplastic meningioma overspreading nearly whole cerebral convexity from main extra-axial tumor bulk in the parietal lobe.
