Cir Cir, 71pp. Pathogenic, diagnostic and therap J Clin Endocrinol Metab, 77pp. These lesions do not cause a hormonal hipopituitarosmo syndrome, and are therefore found incidentally particularly microadenomas or diagnosed based on compressive symptoms such as headache and visual field defects, as well as clinical signs of pituitary hormone deficiencies.

Both techniques present advantages and limitations and ultimately the decision as to which of the two is used in the individual patient depends on the neurosurgeon’s experience and preference.

Non-functioning pituitary microadenomas are diagnosed incidentally when an imaging study, be it MRI or CT is performed for unrelated reasons. If a small less than 6 mm tumor remnant is demonstrated in the postoperative MRI and the patient is asymptomatic, has relative preservation of hormone function and wants to preserve fertility it is reasonable to observe and monitor the lesion periodically.

Hipoptiuitarismo, T1-weighted, gadolinium-enhanced coronal and sagittal views; B, T2-weighted coronal view. Retrospective multicentric study of pituitary incidentalomas. Pathogenic, diagnostic and therapeutic aspects. Since they do not result in a hormonal hypersecretion syndrome, the diagnosis of NFPA is either made incidentally or relies on the detection of symptoms and signs of mass effect such as headaches and visual abnormalities due to optic chiasm compression as well as pituitary hormone deficiencies.

Pediatr Neurol, 50pp. Cancer Res, 67pp. PA had been traditionally classified according to their staining characteristics with hematoxylin and eosin HE as acidophilic, basophilic and chromophobic.

At the other end of the spectrum there are patients in whom acute or even emergency surgery is indicated because of progression of tumor growth with impending visual compromise or intracranial hypertension and in cases of pituitary apoplexy with hemodynamic instability Fig. Acta Neurochirug,pp.
