Parathyroid nodular hyperplasia: when imaging exams fail

Osorio Ana Sofia , Rocha Jose , Faria Carolina , Barbosa David , Nobre Ema , Bugalho Maria Joao

Introduction: Parathyroid hyperplasia is the second cause of primary hyperparathyroidism (PH), representing 15–20% of all cases. The scintigraphy with Tc-99m-Sestamibi is a preoperative exam used to identify parathyroid adenomas or hyperplasia. It has a sensibility of 50–90%, which increases with larger parathyroid size. The neck ultrasonography (US) has also an important role detecting parathyroid enlarged glands with 70% sensibility. We report a case of parathyroid...

Not what it seems: an exuberant case of hirsutism in polycystic ovary syndrome

de Grine Severino Mariana , Vaz Lopes Marta , Peixe Carolina , Vicente Rocha Jose , Lacerda Nobre Ema , Joao Bugalho Maria

Introduction: Hirsutism is the presence of terminal hair growth in females with a male distribution pattern. It affects 5-15% of women, being an important sign of androgen excess. The main causes of hirsutism are polycystic ovary syndrome (PCOS) and idiopathic hyperandrogenism. Other significant but less frequent causes of hirsutism include nonclassic congenital adrenal hyperplasia (NCAH), androgen-secreting tumors, and Cushing’s syndrome.Case repor...

Primary bilateral macronodular adrenal hyperplasia: Is unilateral adrenalectomy enough?

Lopes-Pinto Mariana , Fialho Mafalda Pinho , Ricca Lacerda Nobre M Caetano Ema Paula , Rocha Jose , Barbosa Ana Paula

Introduction: Primary Bilateral Macronodular Adrenal Hyperplasia (PBMAH) represents <2% of causes of Cushing’s Syndrome (CS). Clinical course is insidious, with adrenal bilateral macronodules and gradual cortisol excess, only rarely presenting with overt CS. The pathophysiology remains unclear, however, hyperactivation of the cAMP/PKA pathway, in 77-87% of cases through aberrantly expressed G-protein coupled receptors (GPCRs), has been described. Despite being a benig...

Primary hyperparathyroidism: A rare form of presentation

Lopes Marta Vaz , Rocha Jose Vicente , Peixe Carolina , de Grine Severino Mariana , Gomes Ana Coelho , Bugalho Maria Joao

Introduction: Primary hyperparathyroidism (PHPT) is characterized by parathyroid hormone (PTH) overproduction, causing hypercalcemia. The most common cause is a parathyroid adenoma. PHPT most frequently presents as asymptomatic hypercalcemia or with nonspecific symptoms. Less frequently, it presents with the classical manifestations of bone disease and nephrolithiasis. Acute pancreatitis (AP) as the initial manifestation of PHPT has been reported rarely. Hypercalcemia can caus...
