Meningioma Petroso Posterior Derecho

Abstract

Meningiomas are tumors originating meningothelial arachnoid cells. It has an incidence of 0.3 in 100,000 in teens, increasing with age to 8.4 per 100,000 in older adults, are common in the fifth and sixth decades of life and predominate in females.(1) Are the most common primary intracranial tumors in adults and account for about 30% of them; 90% are benign and are classified according to their pathological and aggressive characteristics. For decades these tumors have been handled in three ways: clinical and imaging observation, surgery, and radiation treatment. (1, 2) The next case to analyze is a patient female, 49 years old, born and resident in Latacunga, with a history of hypothyroidism diagnosed 8 years ago, surgical Background: surgery herniated disc L4-L5, 12 years ago; Family History: diabetic mother + IRC ; father died with prostate cancer, and mesenteric thrombosis.

Patient goes to hospital IESS Latacunga (Emergency) to present repetitive intense holocraneana headache a year of evolution as actual date and two months of evolution as apparent date, predominantly in the right parietal which was treated as a migraine with painkillers in the first months of presentation and gradually was exacerbating episodes of dizziness, vertigo, partial disorientation and memory loss, as well hearing loss in both ears, tinnitus and visual disturbances.

By observing the actual time evolution of this disease, she is derived from the of otolaryngology specialty with suspected pathology or inner ear disorders, but being discarded both the valuation of neurosurgery request more performing:

Simple TAC: isodense multiple images compatible with supratentorial level calcified lesions. In back of the petrous temporal partially calcified lesion of 2.2 x 2.3cm it does not cause displacement or compression of the ventricles is observed. RMN skull: Extra axial tumor lesion in the right cerebellopontine cistern with probable signs of calcification, compatible with meningioma. TAC proven skull: hyperdense level right cerebellopontine angle that captures contrast observed vessels territory of the posterior cerebral nurturing injury.

In the development of this case evolution be appreciated, the elements of diagnosis, differential diagnosis and possible complications taking into account that although it is a benign and rare condition is at risk of malignant transformation and therefore surgical treatment is essential; also it will discuss the stages of life that occurs more frequently and their symptoms and histopathologic classification, same as we will see varies according to the location of the tumor. The event concludes with the surgical resolution of meningioma, without complications. Finally procedure studied, the patient is discharged at 6 days post-surgery with satisfactory evolution.
