A 45-year-old female presented with blurred vision, headache, and abnormal thirstiness. She was not pregnant nor postpartum. She had diabetes insipidus and bitemporal hemianopsia. Radiological evidence suggested a mass arising in the sella turcica with extension into the parasellar and suprasellar regions. Carotid angiography showed occlusions of bilateral internal carotid arteries at the cavernous portions. The mass was subtotally removed by the trans-sphenoidal approach and was histologically diagnosed as an adenohypophysitis. Laboratory data showed the patient to be in an active state of autoimmune disorder and hypopituitarism. When a patient presents with pituitary insufficiency and an enhanced intrasellar mass lesion on computed tomographic scan, lymphocytic adenohypophysitis must be included in the differential diagnosis.

We herein report a case of a variant form of septo-optic-pituitary dysplasia (SOPD). A 40-year-old man was admitted due to sudden occurrence of left blurred vision and lasting polyuria. He showed short statue of height of 144 cm and the neurological examination revealed hypesthesia of the left trigeminal nerve and temporal pallor in the left fundus oculi. Brain MR imaging demonstrated agenesis of the septum pellucidum and hypoplasia of the corpus callosum with subcortical spotty lesions, but optic nerve hypoplasia was not detected. The left eye showed a prolonged P100 latency of pattern reversal VEPs. He was diagnosed as having hypopituitarism since growth hormone-releasing factor did not stimulate growth hormone secretion and restriction of water-intake did not induce secretion of antidiuretic hormone. Thus we regarded this case as a variant form of SOPD. The mutation of HESX 1 gene, however, was not detected in the case. P100 of the left eye showed a reduction in latency four months after discharge. This case was considered to be a variant form of SOPD complicated by acute optic neuritis.

Ovulation induction is seldom reported to cause pituitary abnormality and the physiological enlargement of the pituitary gland during pregnancy is asymptomatic. We report a woman who became pregnant after ovulation induction. She had symptomatic pituitary enlargement with a pituitary height of 2 cm on cranial magnetic resonance imaging (MRI) in the second trimester. Her symptoms (headache and blurred vision) improved greatly after delivery but she had absence of lactation. The height of the pituitary gland decreased to 1 cm on the second cranial MRI 40 days after delivery and her third cranial MRI only revealed a mild central bulge in the pituitary gland eight months after delivery. This article shows that the abnormal enlargement of the pituitary gland during pregnancy might remit spontaneously after delivery and these patients might have higher risk of postpartum hypopituitarism. Neurological symptoms and signs should be closely monitored during pregnancy and neurosurgery may not be necessary. Endocrine surveys should be performed regularly after delivery to detect hypopituitarism as early as possible.

Pituitary abscess is an uncommon pituitary lesion. Its clinical diagnosis can be difficult to distinguish from other pituitary lesions. This pathology is characterised by vague symptoms of headaches, generalised tiredness and hypopituitarism manifestations. A history of recent meningitis, paranasal sinusitis or head surgery can be a suggestive of the source of infection.A 20-year-old man was admitted to neurosurgery department with complain of headache, fatigue, polyuria, polydipsia, blurred vision and sexual dysfunction. MRI of the head revealed a suprasellar mass that was centrally hyperintense lesion on T2-weighted images with peripheral hypointensity and isointense centrally on T1 images with peripheral hyperintensity images. Treatment of this lesion pituitary abscess was surgical drainage of the pituitary area through a trans-sphenoidal approach and broad spectrum antibiotic therapy with ceftriaxone, metronidazole and vancomycin for 6 weeks. The patient continues to have pituitary insufficiency and treated with oral hydrocortisone.Although pituitary abscess is a rare condition, it should always be kept in mind when evaluating a patient with hypopituitarism. After the diagnosis, the surgery and antibiotics should be commenced rapidly. The outcome is usually good with proper treatment.

Primary non-neuroendocrine tumours of the pituitary gland and sella are rare lesions often challenging to diagnose. We describe two cases of clinically aggressive primary glomus tumour of the pituitary gland. The lesions occurred in a 63-year-old male and a 30-year-old female who presented with headache, blurred vision and hypopituitarism. Neuroimaging demonstrated large sellar and suprasellar tumours invading the surrounding structures. Histologically, the lesions were characterised by angiocentric sheets and nests of atypical cells that expressed vimentin, smooth muscle actin and CD34. Perivascular deposition of collagen IV was also a feature. Case 2 expressed synaptophysin. INI-1 (SMARCB1) expression was preserved. Both lesions were mitotically active and demonstrated a Ki-67 labelling index of 30%. Next-generation sequencing performed in case 1 showed no mutations in the reading frame of 37 commonly mutated oncogenes, including BRAF and KRAS. Four pituitary glomus tumours have previously been reported, none of which showed features of malignant glomus tumour. Similar to our two patients, three previous examples displayed aggressive behaviour.
