Type C closely resembles nonfunctioning pituitary adenomas with bitemporal hemianopsia and hypopituitarism. C型类似无功能垂体腺瘤，除视野缺损外，还有双颞侧偏盲。
Polyuria in 3 of 5 patients and hypopituitarism in 2 of 4 patients were improved after operation. 3例尿崩症、2例垂体功能低下改善，1例术后2年复发。
Type B causes fewer visual disturbances, but more memory distubance and hypopituitarism. B型除引起视力障碍外，还有垂体功能低下；
We report a 43-year-old patient of auricular ossification with hypopituitarism and secondary hypoadrenalism to remind clinicans of this somewhat forgotton sign of adrenal insufficiency. 我们报告一例脑下垂体低能症，合并续发性的肾上腺低能症及耳壳骨化，希望此一在肾上腺低能症中被遗忘的症状于理学检查时应该受到重视。
Conclusion:Pituitary abscess should be considered when patients presented diabetes insipidus,hypopituitarism,sella bone erosion and sella neoplasm similar to a cyst tumor in CT or MRI. 结论：若鞍区病变不大，但引起较严重的蝶鞍骨质破坏，表现为尿崩症和垂体功能低下时，应首先考虑垂体脓肿。
