Objective. To report the unusual case of an adrenal lymphangioma presenting in a patient with an adrenal cystic lesion and biochemical testing concerning for pheochromocytoma. The pertinent diagnostic and imaging features of adrenal lymphangiomas are reviewed. Methods. We describe a 59-year-old patient who presented with hyperhidrosis and a 2.2 by 2.2 cm left adrenal nodule. Biochemical evaluat...
Adrenocortical tumour have been described in patients with 21-hydroxylase deficiency. These tumours are usually considered to be ACTH – dependent, as diffuse adrenal cortical hyperplasia is commonly seen. We report adrenal cortical tissue tumours developed in three patients with untreated congenital adrenal hyperplasia due to 21-hydroxylase deficiency. All of them had symptoms of adrenogenital ...
BACKGROUND Cavernous hemangiomas are rare tumors, mainly localized in the liver and skin, but also reported in the cerebellum and eye fundus as a part of von Hippel Lindau Syndrome. Adrenal hemangiomas are less than 1% of all the adrenal neoplasms and usually are reported as benign, non-functioning tumors, originating from the adrenal cortex and surrounded by normal or hyperplastic adrenal tiss...
Abstract Objectives Neuroblastoma (NB) is one of the most common tumor during perinatal period. The clinical features NB occurring in fetuses and neonates differ from that older age groups. Frequently, Congenital neuroblastomas are incidentally detected prenatally. Clinical presentations NBs highy variable. Case presentation A 24-day old preterm 32 weeks’ gestation male neonate developed choles...
introduction the dexamethasone test has been widely used for diagnosing hypercortisolism. materials and methods we assessed the relationship between the basal and suppressed cortisol values in urine and plasma during a low-dose dexamethasone test in patients with proved cushing's disease. results a statistically highly significant correlation was found (for urine cortisol: r = 0.66, p <0.0...
results out of 617 patients, 79.6% had 21-hydroxylase deficiency (21-ohd). in 21-ohd group 94.5% had classical type and 5.5% were non-classic. among the classic type 78% had salt-wasting form (sw) and 22% simple virilizing (sv). both 21-ohd-sv and sw were diagnosed more frequently in females. frequency of other types were as follow: 11-hydroxylase deficiency (11-ohd), 13.3%; 3ß-hydroxysteroid d...
ADRENAL-SPECIFIC RADIOLIGAND, 131I-6β-iodomethyl-19norcholest-5(10)-en-3β-ol (131I-adosterol)1 was developed in the 1970s. Increased uptake of the agent in tumor regardless of visualization of the contralateral gland suggests that the adrenal mass is usually a benign cortical adenoma.2 This agent has the potency to diagnose lesions of the adrenal cortex and has been widely used to diagnose lesi...
Adrenal rest tumor in liver is a very rare tumor. It originates from an adrenal rest, which is derived from the aberrant adrenocortical tissue. Adrenal rest tumor is an ectopic collection of adrenocortical cells in extra-adrenal sites. This tumor may be hormonally active and manifest endocrine syndromes. But, most tumors are non-functioning and benign. Histologically, hepatic adrenal rest tumor...
Primary aldosteronism (PA) is the most common cause of secondary hypertension and consists up to 11% of patients with hypertension. Adrenal venous sampling (AVS) is the recommended procedure for diagnosis of PA, but the technique is difficult and the right adrenal vein is especially hard to catheterize. We retrospectively examined the clinically relevant anatomy of the right adrenal vein in a s...
Phaeochromocytomas (PHEOs) and paragangliomas (PGLs) are catecholamine-secreting tumors, that arise from chromaffin cells of the adrenal medulla and extra-adrenal sites. Extra-adrenal phaeochromocytomas are called paragangliomas (Landers et al., 2005). The Prevalence of these tumors is 1:4500 and 1:1700 and an annual incidence of 3-8 cases per 1 million per year in the general population. PHEOs...
