Background Fibrocystic osteitis is rare PHPT manifestation. Poor management and delay in diagnosis of fibrocystic osteitis may lead to reduced quality of life and also provoke severe postoperative hypocalcemia – «hungry bone» syndrome.Clinical case We present a case of 66-years-old Caucasian woman, with history of urulithiasis/nephrocalcinosis (CKD stage 4), two pathological fractures, and fibrocystic osteitis. In Jan 2021...

Background: Detection of MRI-negative ACTH-producing pituitary adenomas is a challenge in the management of patients with Cushing’s disease. There are some data on the possibility of pituitary adenomas to accumulate 18F-fluorodeoxyglucose (18F-FDG) during the 18F-FDG positron emission tomography and computer tomography (18F-FDG PET/CT).Aim: To study the potential of brain 18F-fluorodeoxyglucose PET/CT for localization of MRI-negative ACTH-producing ...

Purpose: According to modern guidelines late night serum cortisol measurement is not considered to be among the first steps for screening of hypercortisolism. But in some cases it may be useful as it allows identifying the loss of normal circadian rhythm of cortisol secretion. This test is not rarely used in hospitalized patients when Cushing’s syndrome is suspected. But the cutt-off point of nighttime serum cortisol level for the diagnosis of hypercortisolism is inconsis...

Introduction: Growth hormone (GH) level is a direct marker of active residual adenoma tissue after acromegaly surgery. However, the value of early postoperative GH for prediction of surgical cure in acromegaly has not been established and therefore is not used in everyday clinical practice.Aim: The aim of our work was to study the 24-hour basal postoperative GH level and the nadir of GH level after the oral glucose tolerance test (OGTT) two weeks after s...

Purpose: Inferior petrosal sinus sampling (IPSS) is considered the gold standard test for the differential diagnosis of ACTH-dependent Cushing’s syndrome, but false-negative results have been reported in 1–10% cases. Cavernous sinus sampling (CSS) was suggested as a diagnostic tool in a complex ACTH-dependent Cushing’s syndrome cases.Aim: To study the role of bilateral combined cavernous and inferior petrosal sinus samplin...
