Background: The growth hormone (GH)/insulin-like growth factor-1 (IGF-1) axis has effects on renal growth and electrolyte regulation. However, data on adverse renal comorbidities such as renal cysts and stones in acromegaly is scarce. The current study aimed to investigate the prevalence of radiologically detectable renal comorbidities and possible related factors in the acromegaly population.Methods: A total of 125 patients with acromegaly (46.4±11.6...

Aim: To determine whether there is any factor that can predict sufficient results in second thyroid fine-needle aspiration biopsy (FNAB) after first nondiagnostic cytological result.Materials and method: Nodules with non-diagnostic result after first FNAB were included and separated into two groups as sufficient (Group-1) and insufficient (Group-2) second FNAB. Results: Second FNAB was performed on 643 nodules of 443 patients with ...

Objective: Thyroid nodules are one of the most common thyroid diseases. Ultrasonography is an reliable and the most commonly used imaging method in the evaluation of thyroid nodules with a high sensitivity (Sn) and specificity (Sp). The prevelance of obesity, especially severe obesity, is increasing at an alarming rate in the worldwide.

However ACTH secreting adenomas are one of the most common functional pituitary tumors, subtypes such as Crooke cell corticotroph adenoma(CCCA) are relatively rare. We present here a patient with CCCA who had severe hypercortisolism mimicking ectopic ACTH syndrome. A 69 years old female patient admitted to emergency department after a fall. On cranial MRI,’a 3.5x2.5x3cm mass appearance with a sellar-suprasellar location, which is compressing the optic chiasm, expanding th...
