OBJECTIVE Primary central nervous system (CNS) non-Hodgkin's lymphoma is a rarely encountered clinical entity. Here we present a case of a primary CNS diffuse large B-cell non-Hodgkin's lymphoma developed on a previously operated and irradiated pituitary macroadenoma. DESIGN-RESULTS: A 60-year-old woman presented with muscle weakness and eye lid ptosis. Thirty years ago, she was diagnosed with ...

Introduction The ectopic posterior pituitary is an aberrant accumulation of neurosecretory materials at the median eminence or infundibular stem resulting in functional preservation of hormonal production and release, which is often seen in patients with transection of the pituitary stalk (1). W can also be developed due to compression to the hypothalamohypophsial tract by alarge macroadenoma (...

OBJECTIVE To assess frequency, symptoms and outcome of pituitary apoplexy (PA) among pituitary adenoma patients, to gain better insight into risk factors for bleeding into pituitary adenoma and to estimate the sequelae of PA by means of a matched control group. METHOD By reviewing charts of 574 patients with pituitary adenoma, we analysed incidence, symptoms and outcome of PA and potential ri...

Pituitary tumors are benign that occur in the pituitary gland with a presentation of 10% all intracranial tumors. If size tumor is > 1 cm, called macroadenoma, large will have mass effect so there an emphasis on area and its surroundings. This manifest hyposecretion hormones produced pituitary. We report case 57-year-old male complaints decreased vision since 3.5 months. The patient had prev...

The aim is to present unusual clinical course and magnetic resonance imaging (MRI) features of pituitary abscess. A 59-year-old man presented with fever, polyuria, polydipsia and marked weight loss within the last two months. Basic endocrinology tests revealed the presence of anterior pituitary dysfunction, associated with central diabetes insipidus and increased levels of inflammatory markers....

SUMMARY The role of mechanical forces influencing the growth of a pituitary adenoma is poorly understood. In this paper we report the case of a young man with hyperprolactinaemia and an empty sella secondary to hydrocephalia, who developed a macroprolactinoma following the relief of high intraventricular pressure. LEARNING POINTS The volume of a pituitary tumour may be influenced not only by ...

Simultaneous occurrence of morphological distinct, discreet intracranial tumors sharing the same cell lineage is a rarity. Pituitary tumors and craniopharyngiomas share a common lineage. Simultaneous occurrence of these two tumors in the same patient is rare and has been reported only nine times so far (Table 1). While pituitary tumours are centred in the sella, craniopharyngiomas may occur any...

with radiation) is the most common treatment option. Treatment of adenomas with surgery alone is associated with a 9% risk of significant complications other than hypothyroidism. Additionally, there is a significant recurrence risk with surgical treatment alone. Park et al found a 5-year recurrence rate of 15.2% and a 10-year recurrence rate of 50.5% for 132 patients having nonfunctioning macro...
