Pituitary tumour apoplexy is a rare but life threatening condition. Cushing's disease usually presents with clinical features of Cushing's syndrome. We report a 30-year-old male patient with Cushing's disease who presented with severe headache and right third nerve palsy. MRI of the pituitary gland revealed a pituitary adenoma with infarction suggestive of apoplexy. After a transsphenoidal surgery he developed pan-hypopituitarism with diabetes insipidus. We also review the relevant literature.

Cushing's disease (CD) is usually caused by secretion of ACTH by a pituitary corticotroph microadenoma. Nevertheless, 7%-20% of patients present with ACTH-secreting macroadenomas. Our aim is to report a 36-year-old female patient with CD due to solid-cystic ACTH-macroadenoma followed up during 34 months. The patient presented spontaneous remission due to presumed asymptomatic tumor apoplexy. She showed typical signs and symptoms of Cushing's syndrome (CS). Initial tests were consistent with ACTH-dependent CS: elevated urinary free cortisol, abnormal serum cortisol after low dose dexamethasone suppression test, and elevated midnight salivary cortisol, associated with high plasma ACTH levels. Pituitary magnetic resonance imaging (MRI) showed a sellar mass of 1.2 x 0.8 x 0.8 cm of diameter with supra-sellar extension leading to slight chiasmatic impingement, and showing hyperintensity on T2-weighted imaging, suggesting a cystic component. She had no visual impairment. After two months, while waiting for pituitary surgery, she presented spontaneous resolution of CS. Tests were consistent with remission of hypercortisolism: normal 24-h total urinary cortisol and normal midnight salivary cortisol. Pituitary MRI showed shrinkage of the tumor with disappearance of the chiasmatic compression. She has been free from the disease for 28 months (without hypercortisolism or hypopituitarism). The hormonal and imaging data suggested that silent apoplexy of pituitary tumor led to spontaneous remission of CS. However, recurrence of CS was described in cases following pituitary apoplexy. Therefore, careful long-term follow-up is required.

The purpose of this study was to assess gender-related distinction in the performance of Cushing's disease (CD) regarding clinical features, radiological findings, neurological and endocrine status, surgical outcome, and quality of life in Han Chinese. A retrospective study was conducted on 87 patients treated by trans-sphenoidal surgery, between 2006 and 2011, at a single treatment center in Shandong Provincial Hospital, China. Features of CD were compared and quality of life was analyzed between genders. The female-to-male ratio was 2.78: 1. Results showed that men have a younger age of diagnosis (P<0.001), a larger adenoma diameter (P<0.001), and a higher invasion rate (P=0.032) and apoplexy rate (P=0.04) than women. To be specific, compared with women, men are more prone to suffering from osteoporosis, hypokalemia, sexual dysfunction, and hypertension (P<0.05), have significantly higher preoperative and postoperative (six months after surgery) cortisol levels (P<0.001, P=0.003) and a higher recurrence rate (30.43% vs. 7.81%; P=0.028). No significant differences were seen in the CushingQoL scores between genders. Therefore, male patients with CD need more careful and long-term follow-up than female patients.

Clinically NFPA is currently the preferred term for designing all the pituitary adenomas which are not hormonally active (in other words, not associated with clinical syndromes such as amenorrhea-galactorrhea in the context of prolactinomas, acromegaly, Cushing's disease or hyperthyroidism secondary to TSH-secreting adenomas). They account for 15-30% of pituitary adenomas. Diagnosis is usually made either in the context of mass effect due to a macroadenoma or, increasingly, fortuitously during imaging performed for some unrelated purpose; the latter case is known as pituitary incidentaloma. Surgery is indisputably indicated in case of tumoral syndrome, but other aspects of NFPA (hormonal work-up, follow-up, and especially postoperative follow-up, management of remnant or recurrence, the special case of incidentaloma, or apoplexy) remain controversial. The French Endocrinology Society (SFE) therefore set up an expert working group of endocrinologists, neurosurgeons, ophthalmologists, neuroradiologists, pathologists and biologists to draw up guidelines, at the 2012 SFE Congress in Toulouse, France. The present article presents the guidelines suggested by this group of French-speaking experts.

In this double case report, we present two special cases of pituitary apoplexy. First, we describe a patient with growth hormone deficiency despite clinical suspicion of acromegaly. Imaging showed evidence of a recent pituitary apoplexy, which might have caused spontaneous remission of the acromegaly before presentation at our outpatient clinic. Second, we describe a patient who presented with spontaneous remission of Cushing's disease after pituitary apoplexy, followed by a spontaneous remission of a relapse of the Cushing's disease due to a second pituitary apoplexy. These cases show that patients in spontaneous remission of hormonally active pituitary adenomas should be suspected of a pituitary apoplexy. Furthermore, even after spontaneous remission following pituitary apoplexy, careful long-term follow-up of these patients is mandatory, as relapses of hormonal hypersecretion can occur.

An 18-year-old male with Cushing's disease presented with generalised skin eruptions and backache. He was diagnosed with varicella infection. During the course of the illness, he developed persistent vomiting. Hormonal evaluation suggested adrenal insufficiency. MRI of brain showed features of pituitary apoplexy. Initially, he required hydrocortisone replacement. Later on his hypothalamic-pituitary-adrenal axis recovered and he is currently asymptomatic without any treatment.

Pituitary diseases such as acromegaly and Cushing's disease require surgical or medical therapy. In some functioning pituitary tumors, a spontaneous remission of hormonal hypersecretion is observed, mainly associated to apoplexy or pituitary infarction. We report the evolution of two female patients older than 70 years at the time of diagnosis, with multiple comorbidities. In case 1, acromegaly was diagnosed at 74 years of age. Sellar CT scan showed a 10-mm adenoma. During her follow-up, IGF1 levels remained normal. Nine years later, a magnetic resonance (MR) showed a 7-mm adenoma. In case 2, clinical and biochemical diagnosis of Cushing's disease was done being 71 years old. Sellar MR showed a 6-mm adenoma. Three years later, urinary cortisol normalized with no changes in adenoma at MR. Seven years later, she remains without clinical or biochemical signs of hypercortisolism. In both cases, no signs of hemorrhage were observed at MR.

The diagnosis and treatment of pituitary disease in pregnancy represents a special clinical challenge. Not least because there is very little data on the treatment of pregnant patients with pituitary disorders. A selective search of the literature was carried out with the aim of compiling evidence about the diagnosis and treatment of pituitary disease in pregnancy. The search covered the databases PubMed/MEDLINE including PubMed Central and also used the Livivo (ZB MED) search engine. Recent studies were evaluated for recommendations about the care of pregnant patients with hormone-inactive and hormone-active pituitary adenomas (prolactinoma, acromegaly and Cushing's disease), pituitary insufficiency, pituitary apoplexy and hypophysitis. The most well-established forms of treatment are for prolactinoma, due to the incidence of this disease and its impact on fertility. When pregnancy has been confirmed, prolactinoma treatment with dopamine agonists should be paused. Although microprolactinomas rarely increase significantly in size after the administration of dopamine agonists is discontinued, symptomatic tumor growth of macroprolactinomas can occur. In such cases, treatment with dopamine agonists can be resumed. If the primary tumor is large and the risk that it will continue to grow is high, it may be necessary to continue medical treatment from the start of pregnancy. If one of the partners has a pituitary disorder, it is often still possible for many couples to achieve their wish of having children if they receive medical support to plan and the pregnancy is carefully monitored. Given the complexity of pituitary disease, pregnant patients with pituitary disorders should be cared for and treated by a multidisciplinary team in centers specializing in the diagnosis and treatment of pituitary disease.

Pediatric pituitary adenomas (PPAs) are rare neoplasms with a propensity for unusual presentations and an aggressive clinical course. Here, the authors describe 6 highly atypical PPAs to highlight this tendency and discuss unexpected management challenges.A 14-year-old girl presented with acute hemiparesis and aphasia. MRI revealed a pituitary macroadenoma causing internal carotid artery invasion/obliteration without acute apoplexy, which was treated via emergent transsphenoidal resection (TSR). Another 14-year-old girl developed precocious galactorrhea due to macroprolactinoma, which was medically managed. Several years later, she re-presented with acute, severe, bitemporal hemianopia during her third trimester of pregnancy, requiring emergent induction of labor followed by TSR. A 13-year-old boy was incidentally diagnosed with a prolactinoma after routine orthodontic radiographs captured a subtly abnormal sella. An 18-year-old male self-diagnosed pituitary gigantism through a school report on pituitary disease. A 17-year-old boy was diagnosed with Cushing disease by his basketball coach, a former endocrinologist. A 12-year-old girl with growth arrest and weight gain was diagnosed with Cushing disease, which was initially treated via TSR but subsequently recurred and ultimately required 12 operations, 5 radiation treatments involving 3 modalities, bilateral adrenalectomy, and chemotherapy. Despite these efforts, she ultimately died from pituitary carcinoma.

Interventional neuroradiology (INR) has evolved from a hybrid mixture of daring radiologists and iconoclastic neurosurgeons into a multidisciplinary specialty, which has become indispensable for cerebrovascular and neurological centers worldwide. This manuscript traces the origins of INR and describes its evolution to the present day. The focus will be on cerebrovascular disorders including aneurysms, stroke, brain arteriovenous malformations, dural arteriovenous fistulae, and atherosclerotic disease, both intra- and extracranial. Also discussed are cerebral vasospasm, venolymphatic malformations of the head and neck, tumor embolization, idiopathic intracranial hypertension, inferior petrosal venous sinus sampling for Cushing's disease, and spinal interventions. Pediatric INR has not been included and deserves a separate, dedicated review.
