Pituitary incidentaloma

Pituitary incidentaloma.

All patients with pituitary incidentaloma should be investigated for pituitary hyperfunction. The single most important test is measurement of serum prolactin (PRL). Elevated PRL can indicate either direct tumour secretion (levels are typically 800–2,000 mU/l for microprolactinoma, >2,000 mU/l for macroprolactinoma and <600 normally) or ‘disconnection’ of the hypothalamus and normal pituitary g...

Acromegaloidism Associated with Pituitary Incidentaloma.

Acromegaloidism with pituitary microadenoma has not been previously reported. We present a case of a 28-year old male with typical features of acromegaly for 11 years.with a pituitary tumor. He had characteristic acromegaloid facial features, clubbing of hands and feet, enlargement of fingers and toes. The natural history of the disease is reviewed and the differential diagnosis is discussed.

A survey of pituitary incidentaloma in Japan.

OBJECTIVE The development of computed tomography (CT) and magnetic resonance imaging (MRI) has resulted in the discovery of unsuspected endocrinologically silent pituitary masses (pituitary incidentalomas). The aim of this study was to perform a national survey on pituitary incidentalomas in order to establish an appropriate approach to them. DESIGN AND METHODS Five hundred and six patients w...

Pituitary “incidentaloma”: Neuroradiological assessment and differential diagnosis

Large pituitary incidentaloma in a patient with sarcoidosis

A 60 year old male with a medical history of pulmonary sarcoidosis and chronic low testosterone presented to his allergist for excessive lacrimation. Computed tomography (CT) scan of sinuses ordered for possible blocked nasolacrimal duct revealed an abnormal expansion of the sella turcica. Magnetic resonance imaging suggested a homogeneously enhancing 4 cm soft tissue mass enveloping the intern...
