Synthetic GH secretagogues (GHSs; GH-releasing peptides and their nonpeptide mimetics) stimulate GH release, activate the hypothalamo-pituitary-adrenal axis, and release PRL in vivo. Patients with acromegaly show an exuberant GH response to GHSs, whereas patients with pituitary-dependent ACTH-secreting tumors show an exaggerated rise in ACTH and cortisol. We, therefore, studied the presence of ...
, the tumor did show up as a focal " hot spot " on subsequent PET scanning (Fig 1). A gated MRI of the hot spot gave further, accurate localization. PET scanning therefore localized the tumor when other modalities had failed. In the second case (patient 2), an atypical carcinoid (moderately differentiated neuroendocrine tumor), the tumor was localized with a CT scan of the chest but subsequent ...
Primary ovarian carcinoid tumors of the ovary are rare and represent less than 0.1% of ovarian malignancy. One of its subtypes is the strumal carcinoid in which the thyroid tissue is seen in intimate association with carcinoid tumor. We here report a 47-year-old woman with strumal carcinoid of the right ovary presented with cessation of menstrual periods in the past 3 months and was referred du...
several cases reported in the literature1,3,5--7 (in addition to our case) where 18FDG-PET (alone or combined with CT) was of value for the localization of occult ECS due to carcinoid tumor. Moreover, various studies have shown its value in detecting neuroendocrine tumors in general (secreting and non-secreting),8,9 mainly atypical ones (showing greater hypermetabolism).10 The development of ne...
Background : Carcinoids are neuroendocrine tumors that typically occur in the gastrointestinal and respiratory systems. Carcinoid middle ear rare. Herein, we report a case of carcinoid developed spinal metastasis required decompression surgery more than 20 years after initial surgery.
Abstract Carcinoid tumors are well differentiated neuroendocrine tumors with secretory components. These tumors are uncommon but the most common primary tumors of the distal small intestine. We present a rare terminal ileum carcinoid tumor presenting with a small bowel obstruction. A 65 years old man presented with intermittent, gen-eralized, dull and colicky abdominal pain accompanied with int...
