Background. Adrenal collision tumors (ACTs), in which distinct tumors coexist without intermingling in the same adrenal gland, are rare and their actual prevalence is unknown. ACTs commonly consist of adrenal cortical adenoma, pheochromocytoma, or metastatic malignant tumor. Case Report. A 32-year-old woman who had been experiencing gastric discomfort for one month was referred to our hospital ...

OBJECTIVE The purpose of our study was to evaluate the utility of apparent diffusion coefficient (ADC) values for characterizing adrenal lesions and determine if diffusion-weighted imaging (DWI) can distinguish lipid-rich from lipid-poor adenomas. MATERIALS AND METHODS We retrospectively evaluated 160 adrenal lesions in 156 patients (96 women and 60 men; mean age, 63 years). ADCs and signal i...

Congenital adrenal hyperplasia (CAH) with 17α-hydroxylase/17,20-lyase deficiency is usually characterized by hypertension and primary amenorrhea, sexual infantilism in women, and pseudohermaphroditism in men. hypertension, and sexual infantilism in women and pseudohermaphroditism in men. In rare cases, a huge adrenal gland tumor can present as a clinical manifestation in untreated CAH. Adrenal ...

BACKGROUND Ultrasonography to visualize adrenal gland lesions and evaluate incidentally discovered adrenal masses in dogs has become more reliable with advances in imaging techniques. However, correlations between sonographic and histopathological changes have been elusive. The goal of our study was to investigate which ultrasound features of adrenal gland abnormalities could aid in discriminat...

We report a 32-year-old female case of a right adrenal gland mass detected on CT scan at medical checkup. CT and MRI showed a mass of 5.1 cm made of fat and calcification in the right adrenal gland, leading to the clinical diagnosis of adrenal myelolipoma. Because of its relatively large size and the patient's desire, the patient underwent gasless single-port retroperitoneoscopic adrenalectomy ...

Frequent use of abdominal ultrasonography (USG) increases discovery of incidental adrenal tumors. Our experience and concise review of recent opinions on management of adrenal incidentalomas is presented. In four out of 23 patients with adrenal incidentalomas false positivity of USG was found (all on the left side), 4 cases were identified as pseudoadrenal masses. Hormonal activity was proved i...

Adrenocortical carcinoma (ACC) is an uncommon malignancy originating from cortex of adrenal gland. The most common pitfall in diagnosis of ACC is to distinguish it from pheochromocytoma. Here we report a 62-year-old hypertensive man with presentation of dyspnea. The laboratory data showed an increase in urine cortisol and renin with a mild increase in aldosterone, but decrease in adrenocorticot...

The existence of renin in the adrenal gland of the mouse was determined by its enzymatic activity and by immunohistochemical techniques using monospecific antibodies to mouse submandibular gland renin. The adrenal gland of mouse was found to contain a very high level of renin significantly greater than other mouse tissues except for the kidney and submandibular gland. Also, the renin level in m...

There are few reported series of endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) of the right adrenal gland, probably because sampling of this gland at EUS is technically more difficult, given its retrocaval location and long endoscope position [1–4]. Here, we describe two successful cases of EUS-FNA of the right adrenal gland without any immediate or delayed complications. Prior ...

BACKGROUND Thyroid nodules with cystic content or mixed sponge-like aspect on ultrasonography and a concordant cytology are strongly predictive of benignity. OBJECTIVES We present 8 patients with honeycomb-like papillary thyroid carcinoma with multiple small cysts on ultrasonography. METHODS The patients were 6 women and 2 men aged between 30 and 57 years. The tumors of these patients showe...
