Petrosal sinus sampling

Young Soo Chung, Minkyun Na, Cheol Ryong Ku, Se Hoon Kim, Eui Hyun Kim
Esthesioneuroblastoma as a source of ectopic Cushing's syndrome is rare, and to the best of our knowledge, only 20 cases have been reported worldwide. A 46-year-old healthy man visited a local clinic for general weakness and hyposmia, and underwent examination with serial endocrinological workup and brain imaging. 68 Gallium-DOTA-TOC positron emission tomography scan was helpful where diagnosis of sellar MRI and inferior petrosal sinus sampling were discordant. Combined transcranial and endoscopic endonasal approach surgery was performed, and a diagnosis of esthesioneuroblastoma was given...

Objective: Glaucoma is a well-recognized side effect of corticosteroids. However, steroid-induced glaucoma typically refers to that caused by exogenous corticosteroid administration. Glaucoma secondary to endogenous overproduction of corticosteroids has only been reported in a few case reports. We aim to bring attention to glaucoma as a rare but important manifestation of endogenous hypercortisolism. Methods: Patient history, physical exam, laboratory results, and imaging studies were reviewed...

The authors report the case of a 30-year-old female patient with suspected Cushing's disease with an anatomical variation of hypoplastic inferior petrosal sinuses and nearly exclusive anterior drainage from the cavernous sinus, who underwent external jugular venous blood sampling with successful disease confirmation and microadenoma localization. The patient presented with signs and symptoms consistent with Cushing's syndrome, but with discordant preliminary diagnostic testing. She underwent attempted bilateral inferior petrosal sinus sampling; however, she had hypoplastic inferior petrosal sinuses bilaterally and predominantly anterior drainage from the cavernous sinus into the external jugular circulation...

Cushing's syndrome (CS) is a classical rare disease: it is often suspected in patients who do not have the disease; at the same time, it takes a mean of 3 years to diagnose CS in affected individuals. The main reason is the extreme rarity (1-3/million/year) in combination with the lack of a single lead symptom. CS has to be suspected when a combination of signs and symptoms is present, which together make up the characteristic phenotype of cortisol excess. Unusual fat distribution affecting the face, neck, and trunk; skin changes including plethora, acne, hirsutism, livid striae, and easy bruising; and signs of protein catabolism such as thinned and vulnerable skin, osteoporotic fractures, and proximal myopathy indicate the need for biochemical screening for CS...

Endoscopic transsphenoidal surgery is a form of treatment for Cushing's disease that is initially preferred compared with other types of treatment. Peritumoral tissue is inactivated by cauterization if a clear border of the lesion cannot be identified. In order to compare the surgical outcomes and post-operative complications between patients who underwent inactivation (cauterization of peritumoral tissues is referred to as inactivation) and those who did not, the medical records of patients treated between January 2010 and June 2016 were retrospectively reviewed...

CONTEXTS: Bilateral inferior petrosal sinus sampling (BIPSS) can differentiate Cushing's disease (CD) and ectopic ACTH syndrome (EAS). The traditional cutoff of inferior petrosal sinus to peripheral (IPS:P) ACTH gradient was 2 before stimulation and 3 after stimulation, which yielded unsatisfactory sensitivity in some studies. OBJECTIVES: To determine the optimal cutoff in BIPSS before or after desmopressin stimulation, and to evaluate the necessity of stimulation...

BACKGROUND: Clinical care of patients with cyclic Cushing's syndrome (CS) is challenging. Classical pitfalls include incorrect subtyping, unnecessary surgical procedures and delayed definite treatment. CASE PRESENTATION: A 43-year-old female suffered from a rapidly cycling ectopic CS. She experienced six cycles of severe hypercortisolism within a 2 year period (maximum plasma cortisol 5316 nmol/L, normal range 124.2-662.4 nmol/L; maximum urinary free cortisol 79,469 nmol/24 h, normal range < 414 nmol/24 h) lasting 2-9 weeks...

Nocardia spp. is a genus of Gram-positive bacteria which can cause cutaneous, pleuropulmonary, or disseminated disease. The latter two forms are encountered in immunocompromised patients, with prolonged usage of corticosteroids being a well-recognized risk factor. However, endogenous Cushing's syndrome is less frequently associated with nocardiosis. We report on a 40-year-old woman who presented for further workup of abnormal findings in the chest computed tomography (three lung nodules, one of which being cavitary)...

Summary: ACTH-dependent hypercortisolism is caused by an ectopic ACTH syndrome (EAS) in 20% of cases. We report a rare cause of EAS in a 41-year-old woman, presenting with clinical features of Cushing's syndrome which developed over several months. Biochemical tests revealed hypokalemic metabolic alkalosis and high morning cortisol and ACTH levels. Further testing, including 24-hour urine analysis, late-night saliva and low-dose dexamethasone suppression test, confirmed hypercortisolism...

Here we describe the bony anatomy of the inner ear and surrounding structures seen in three plesiomorphic crown mammalian petrosal specimens. Our study sample includes the triconodont Priacodon fruitaensis from the Upper Jurassic of North America, and two isolated stem therian petrosal specimens colloquially known as the Höövör petrosals, recovered from Aptian-Albian sediments in Mongolia. The second Höövör petrosal is here described at length for the first time. All three of these petrosals and a comparative sample of extant mammalian taxa have been imaged using micro-CT, allowing for detailed anatomical descriptions of the osteological correlates of functionally significant neurovascular features, especially along the abneural wall of the cochlear canal...

Summary: Ectopic ACTH-secreting pulmonary neuroendocrine tumors are rare and account for less than 5% of endogenous Cushing’s syndrome cases. We describe an unusual case of metastatic bronchial carcinoid tumor in a young woman presenting with unprovoked pulmonary emboli, which initially prevented the detection of the primary tumor on imaging. The source of ectopic ACTH was ultimately localized by a Gallium-DOTATATE scan, which demonstrated increased tracer uptake in a right middle lobe lung nodule and multiple liver nodules...

Background Cyclic Cushing's disease (CCD) is reported to occur in approximately 15% of patients with Cushing's disease (CD). CCD is a rare phenomenon in children. Case presentation A Portuguese female with well-controlled type 1 diabetes (T1DM) on an insulin pump developed transient uncontrolled blood sugar every morning. Increased basal and bolus insulin dosing was ineffective in lowering blood sugar and she began to miss school because of nausea, vomiting, fatigue, but no ketoacidosis. Therefore, other causes of sporadic hyperglycemia were explored...

BACKGROUND: Asymmetric inferior petrosal sinuses (IPS) are not infrequently encountered during bilateral IPS sampling. There is little data on whether IPS symmetry influences success in predicting the adenoma side in patients with ACTH-dependent Cushing's syndrome (CS). OBJECTIVE: To assess the influence of IPS drainage patterns on detection of an adenoma in CS. METHODS: Retrospective single-center cohort analysis reviewing records of patients with CS and negative MRI findings who subsequently underwent BIPSS...

Treatment of Cushing syndrome depends on diagnosis of etiology responsible for hypercortisolism in the body, which sometimes presents with a challenge. Inferior petrosal sinus sampling for ACTH levels, followed by peripheral venous sampling is a proven tool to be a gold standard for differentiating between peripheral and central cause of ACTH dependent Cushing syndrome. This case report is of an elderly female who presented as an outpatient in the endocrinology clinic of Aga Khan university hospital on 22/6/2017 with clinical features of hypercortisolism...

Cushing's syndromes (CS) due to thymic carcinoids are rarely seen. In this text, a case with CS due to ectopic adrenocorticotropic hormone (ACTH) secreting atypical thymic carcinoid tumor is presented. A 50-year-old Turkish male patient was admitted to our emergency department with typical CS features. Basal hormone profile, low- and high-dose dexamethasone suppression tests, and inferior petrosal sinus sampling results were consistent with ectopic ACTH secretion. Thorax computerized tomography showed an upper mediastinal mass, and trans-thoracic biopsy showed atypical thymic carcinoid with positive ACTH staining...

A 69-year-old man was admitted because of subacute development of lower limb weakness from one month ago. He showed central obesity, gynecomastia, dorsal fat pad ("buffalo hump"), and proximal muscle weakness in the lower extremities (manual muscle test 4). Needle EMG, muscle MRI and labolatry screening including CPK were negative for neuromuscular diseases, except for the hypogenitalism accidentally detected in MRI. Although blood corticol was in normal range, the levels of serum ACTH and 24-hour urinary free cortisol excretion were high, and the dexamethasone suppression tests were positive...
