Pituitary stalk lesions.
PURPOSE OF REVIEW To describe the diverse causes of pituitary stalk lesions, their diagnosis, and treatment. RECENT FINDINGS Pathology of the pituitary stalk is often distinct from disease processes that affect the hypothalamus and/or pituitary. Pituitary stalk lesions fall into one of three categories: congenital, inflammatory/infectious, and neoplastic lesions. SUMMARY Stalk thickening ma...
full textCT of the normal pituitary stalk.
A prospective study assessed the size and frequency of visualization of the normal pituitary stalk on high-resolution computed tomography (CT). The normal pituitary stalk can be seen on the vast majority of high-resolution scans obtained with thin sections and intravenous contrast material. The upper size limit of the normal pituitary stalk is 4 mm at the level of the dorsum sellae and 4.5 mm a...
full textCT of the abnormal pituitary stalk.
Seven cases are presented in which enlargement of the pituitary stalk was demonstrated by computed tomography (CT). Histiocytosis X, sarcoidosis, and metastatic cancer were the proven or presumed causes. The discovery of pituitary stalk enlargement prompted radiation treatment in three patients and led to the diagnosis of previously unsuspected diabetes insipidus in one.
full textHyperprolactinemia associated to calcification of the pituitary stalk. Case report.
In this work, the authors report the case of a female patient with 24 years of age with hyperprolactinemia, who presented a pituitary stalk calcification as seen by CT scan. Once other possible etiologies were excluded, we concluded that the calcification was probably related to hyperprolactinemia caused by interruption of the input of dopamine to the pituitary gland.
full textMicroscopic surgery for pituitary adenomas to preserve the pituitary gland and stalk.
Surgery is the primary treatment of choice for all symptomatic pituitary adenomas except prolactinomas. Common postoperative complications include endocrinopathies, vision impairment and cerebrospinal fluid leak. The present study assessed 153 continuous microscopic surgeries for pituitary adenomas performed by an author of the present study between 2010 to 2014. Patients underwent either trans...
full textGranular Cell Tumor in the Pituitary Stalk: A Case Report
Granular cell tumors (GCTs) have been reported in various tissues, especially the skin and subcutaneous soft tissue of the head and neck. We report a 60-year-old man who presented with intermittent headache and dizziness for 3 months, but no other neurological symptoms. Magnetic resonance imaging (MRI) showed the presence of a mass in the pituitary stalk, and contrast-enhanced MRI showed nodula...
