Introduction: Pheochromocytoma is a rare tumor originating from the embryonic neural crest and secreting high levels of catecholamines. The average pheochromocytoma size is 7 cm in the previous publications (1). Sometimes these tumors may be bigger. In this abstract, a case of pheochromocytoma with a huge size presented with unusual presentation.Case study: Fifty-six year-lady presented with an incidental finding of suprarenal mass 14.5 cm after an inves...

Thirty-eight years gentleman presented with DKA as the first presentation of his diabetes. His HbA1c was 12%. On exam, he showed features of Acromegaly and normal BMI. His Growth hormone and IGF-1 were very high in confirming the diagnosis of Acromegaly. His Anti GAD and Anti Islet cell antibodies are negative. MRI dedicated pituitary showed pituitary macroadenoma. Treatment of his DKA was difficult. He was discharged on insulin. Later, the patient was seen in the endocrine cl...

Background: In the majority of cases, the results of TFTs are straightforward. In significant subgroup of patients, the interpretation of TFTs is more challenging, either because. The results appear discordant with the clinical picture (e.g. normal TSH in a patient with suspected thyrotoxicosis), Or measurements appear to contradict each other (e.g. raised TH concentrations, but with non-suppressed TSH).Case presentation: 29 year old Caucasian female com...

Introduction: The diagnosis of hereditary hemorrhagic telangiectasia (HHT) is definite if 3 of the following criteria are present, possible or suspected if 2 are present and unlikely if fewer than 2 are present:• Epistaxis.• Telangiectasias.• Visceral lesions: gastrointestinal, pulmonary, hepatic, cerebral and spinal).• Family history: a first-degree relative with HH...

Isolated hyperreninemic hypoaldosteronism presents in infancy with failure to thrive, hyponatremia, hyperkalemia, markedly elevated plasma renin activity, and low or inappropriately normal aldosterone. It is usually caused by mutations in the CYP11B2 gene encoding aldosterone synthase. Patients have normal cortisol levels and no features of congenital adrenal hyperplasia. We report a patient who presented with hyperreninemic hypoaldosteronism in early infancy.<p class="abs...

Hashimoto’s thyroiditis (HT) is the most common inflammatory condition of the thyroid gland. In addition to the classic variant of HT, several other subtypes have been identified, such as the fibrous variant (HTFV).Case history: A 38 years old man noticed a rapidly enlarging lump in his neck month ago. This resulted in discomfort with choking sensation and mild dysphagia. He mentioned weight loss, tiredness and night sweats. He was a smoker and dran...

The co-existence of thyrotropin (TSH) and growth hormone (GH) secreting pituitary adenoma is exceedingly rare. Less than 15 cases having been reported.Case report: A 75 years’ old man presented with new-onset atrial fibrillation. He had high FT4 with normal TSH. His ultrasound scan of the neck showed a solitary nodule. He had ablation twice and was started on bisoprolol and anticoagulant. He had an MRI scan for headaches and this showed a pituitary ...
