We report a case of 29-year-old woman referred to us for management of refractory epilepsy. Under observation, she was detected to have recurrent hypoglycaemia during the episodes of seizures. On investigation, she was found to have hyperinsulinemic hypoglycaemia. Her triple-phase CT scan of abdomen
The article briefly reviews the specific features of target-organ lesions in multiple endocrine neoplasia type 1 (MEN1) syndrome and a clinical case of genetically confirmed MEN1 syndrome in a young female patient. Despite the relative rarity of this disease, timely diagnosis, treatment and
Hypoglycemia is a well recognized cause of acute symptomatic seizures. The fact that hypoglycemia can cause peripheral neuropathy is less appreciated. We describe a case of insulinoma associated peripheral neuropathy. A 17 year-old previously healthy man was referred for investigation of refractory
Multiple endocrine neoplasia (MEN) mutation is an autosomal dominant disorder characterized by the occurrence of parathyroid, pancreatic islet, and anterior pituitary tumors. The incidence of insulinoma in MEN is relatively uncommon, and there have been a few cases of MEN manifested with insulinoma
Pancreatic neuroendocrine tumors may be associated with multiple endocrine neoplasia type 1 (MEN1) in 15-25% of cases, and up to 10% develop insulinomas, which are the most frequent cause of persistent hyperinsulinemic hypoglycemia in adults. The objective is to show a clinical case that presents
Insul(in)oma is a usually solitary or, in some cases, multifocal tumor of pancreatic beta cells. It may be a component of multiple endocrine neoplasia type 1. or von Hippel-Lindau syndrome. In typical forms the diagnosis - based on the Whipple triad - is simple, however, it may be difficult to
MEN-1 is an autosomal dominantly inherited disorder, characterised by the occurrence of multiple tumours, particularly in the parathyroid glands, the pancreatic islets, the pituitary gland and the adrenal glands, as well as by neuroendocrine carcinoid tumours. Various clinical manifestations are
Since 1982, 25 consecutive patients with benign sporadic (non-multiple endocrine neoplasia type I) insulinomas have been studied. Most were referred because either the tumor was not identified at the referring institution or the diagnosis was unclear. Each patient suffered severe neuroglycopenic
Insulinomas are rare, functional pancreatic neuroendocrine tumors arising from the pancreatic multipotent stem cells or neuroendocrine islet, occurring with a higher proportion in females. Majority of insulinomas have a sporadic etiology; however, only 5%-10% develop as a part of multiple endocrine
Eighteen cases of insulinoma treated at the Instituto Nacional de la Nutricion in Mexico City are presented. The cases were operated on between 1959 and 1988, and include 10 women and 8 men with a mean age of 38. The duration of symptoms ranged between 4 and 96 months with a median of 27; 78% of the
Multiple endocrine neoplasia (MEN1) is a rare autosomal dominant disorder characterized by primary hyperparathyroidism, enteropancreatic neuroendocrine tumors, and anterior pituitary adenomas. A 16-year-old male presented to the emergency outpatient clinic with tonic convulsions. Physical
A 23-year-old male was referred to our hospital for evaluation of new-onset seizures. Signs and symptoms of neuroglycopenia, including weakness, dizziness, and confusion, appeared during fasting and resolved promptly with intravenous dextrose administration. Insulin, proinsulin, and C-peptide levels
BACKGROUND
Hyperinsulinism is the most common cause of recurrent and persistent hypoglycemia in infancy and childhood. Causes can include nesidioblastosis, pancreatic islet cell tumors such as insulinoma, and associations with multiple endocrine neoplasia syndromes. Although new, improved imaging
BACKGROUND
Insulinomas, which are rare tumors causing hyperinsulinemic hypoglycemia are usually sporadic but may also occur in association with multiple endocrine neoplasia type 1 (MEN-1) syndrome an autosomal dominant disorder caused by MEN1 gene mutations. MEN1 encodes a nuclear protein Menin, a
A 9-year-old boy with convulsions is herein described. He was diagnosed and treated for epilepsy and insufficient adrenal function for four years with no response. Hypoglycemia from hyperinsulinism was found and the source of the hyperinsulinism was a tumor of the tail of the pancreas--located by
