RADIOLOGICAL EXAMINATION OF SELLAR TURCLEA IN PATIENTS WITH PITUITARY ADENOMAS

By

Abstract

Neoplasm or tumor according to eminent British Oncologist, Willis, is an
abnormal mass of tissue, the growth of which exceeds and in uncoordinated with
that of normal tissue and persist in the same excessive manner after cessation of
the stimulus which evoked the change1. All tumors are grouped into two broad
categories-benign and malignant depending on their level of anaplasia and
proliferation. Benign tumors are designated by attaching the suffix -oma to the
cell of origin. Tumors of epithelial origin or tumors derived from glands are
termed adenoma. Therefore pituitary adenoma is an abnormal growth of the
pituitary gland.
Owing to the fact that this growth is abnormal, it is purposeless and preys on
the host and above all. it disrupts the structure and function of the organ involved.
In pituitary adenoma, the functionality and structure of the pituita~y gland is
uttered. This impairment of pituitary gland function which is the master gland
whose secretion controls other endocrine gland results in a hydra- headed effect as
it lead to the impairment of growth, lactation, female reproduction functioning,
thyroid functioning and adrenal gland function. It is therefore imperative that
accurate diagnosis of pituitary adenoma be made at the early stage to forestall these ugly incidences.
