Hipofisitis linfocitaria primaria. Caso clínico / Primary lymphocytic hypophysitis. Report of one case

Primary lymphocytic hypophysitis is an autoimmune disease characterized by lymphocytic infiltration of the pituitary gland, with a higher incidence during late pregnancy and the postpartum period. It causes glandular destruction, mass effect and symptoms such headache, visual field defects, ophthalmoplegia and symptoms of hypopituitarism. We report a 38-year-old postpartum woman who, after giving birth presented decreased left visual acuity associated with a non ictal headache. Magnetic resonance imaging demonstrated a sellar mass associated with decreased free thyroxine and cortisol levels. Suspecting a primary lymphocytic hypophysitis, she was treated with prednisone 60 mg/day and hormonal replacement therapy. One month later, size of the pituitary gland decreased, and the visual field defect improved. Steroidal treatment was maintained for 36 months and progressively tapered. After two years of follow-up, the imaging studies show a normal sized pituitary gland.

A trial of Oral Glucocorticoids in the resolution of recurrent Granulomatous Hypophysitis: A case report / Journal of the ASEAN Federation of Endocrine Societies

@#Granulomatous hypophysitis is an extremely rare condition, with no established definitive treatment. An elderly Asian woman was diagnosed to have recurrent granulomatous hypophysitis 5 years after transsphenoidal surgery. No other intervention was done post-operatively. Since another surgery was not advisable due to the high probability of recurrence, she was started on a trial of oral glucocorticoids. After 3 months of steroid therapy, complete resolution of symptoms and sellar mass were achieved.

Idiopathic Granulomatous Hypophysitis with Rapid Onset: A Case Report

Idiopathic granulomatous hypophysitis (IGH), a rare disease, requires differentiation from more common mass lesions of the sella such as pituitary adenoma, craniopharyngioma, Rathke's cleft cyst, or pituitary tuberculoma. IGH usually presents with an insidious onset of visual defects and headaches. On the other hand, rapid onset of neurologic and visual symptoms in an IGH patient is exceptionally rare. Here, we present a biopsy-proven case of IGH with rapid onset and satisfactory outcome after high dose steroid treatment.

Primary hypoparathyroidism and non-functioning pituitary adenoma: An incidental coexistence? / Journal of the ASEAN Federation of Endocrine Societies

@#Primary hypoparathyroidism is caused by a group of heterogeneous conditions in which hypocalcemia and hyperphosphatemia occur as a result of deficient parathyroid hormone (PTH) secretion. The most common cause is surgical excision and damage to the parathyroid gland(s). Nonetheless, autoimmune endocrine disorder of primary hypothyroidism has been well-described in polyglandular autoimmune syndromes (PAS).1 Its association with pituitary lesion may be autoimmune lymphocytic hypophysitis as the cause for pituitary disorder. In this report, we encountered a patient with primary hypoparathyroidism who had a non-functioning pituitary tumour. It was confirmed as pituitary adenoma rather than lymphocytic hypophysitis from the histopathological examination. To our knowledge, this is the first reported case of non-functioning pituitary macroadenoma and primary hypoparathyroidism.
