Clinical Detection and Treatment of Benign and Malignant Pituitary Diseases
The pituitary gland weighs about 0.5-1 g and is divided into an anterior and a posterior lobe. The pituitary gland sits in the sella turcica immediately behind and superior to the sphenoid sinus. Cavernous sinuses are located laterally on each side of the sella and include the internal carotid artery and cranial nerves III, IV, V1, V2, and VI. Magnetic resonance imaging (MRI) is the best method for visualization of hypothalamic-pituitary anatomy (Figure 17.1). Anterior pituitary hormones are regulated by hypothalamic releasing and inhibitory hormones as well as negative feedback action of the target glandular hormones at both the pituitary and hypothalamic levels (Table 17.1).
