A 57-year-old woman complaining of hypertensive attacks associated with headache and palpitation was admitted to our hospital for examination of bilateral adrenal tumors in 1985. After right pheochromocytoma was diagnosed, right adrenalectomy was performed. The left adrenal tumor was small; thus, the left adrenal tumor was preserved to avoid adrenal insufficiency, although left adrenal pheochromocytoma could not be denied. In 1995, she was referred to our clinic again because of recurrent headache and palpitation, and enlargement of the left adrenal tumor. Although pheochromocytoma was suspected again, the enlarged left adrenal turned out to be a nonfunctioning cortical adenoma. This case was interesting, not only because of difficulty in identifying the left adrenal tumor, but also because of the rare coexistence of a pheochromocytoma and a nonfunctioning adrenal cortical tumor.

Fifty-six patients with craniopharyngiomas were operated by microsurgical techniques during a 20-year period. Of the 56 patients, 28 were males and 28 were females, with a mean age of 33 years (range 1 to 78 years). Twenty patients (35.7%) were less than 15 years of age. Remission was defined as clinical improvement with stable ophthalmological and neurological status, CT and/or MRI evidence of a decrease in tumor size or tumor disappearance when a patient was discharged from hospital. Ineffectiveness was defined as lack of change in the preoperative clinical status. The mean follow-up period in this study was 6.9 years, with 11 patients monitored. The most common presentation was visual dysfunction (69.6%). 33.9% of the patients presented with headache. The most frequent preoperative finding was a visual field defect, with 55.4% of the patients so affected; 39.5% of patients had preoperative hypothyroidism and 40% had hypoadrenalism. Diabetes insipidus was found preoperatively in 7.1%. Three female patients had amenorrhea. Hydrocephalus was uncommon, being present in only 10.7%. Unruptured aneurysms were found incidentally in 2 cases. A pterional approach was used in 29 patients (52%), a transcallosal approach in 13 (23%), a transcortical approach and a transsphenoidal approaches in 3 (5%), and a lamina terminalis approach in 1 patient. Multiple procedures were required in 8 patients in order to provide significant relief of compressive symptomatology. Overall, 12.5% of the tumors were completely resected. 92.9% of our patients were in remission, 2 had ineffectiveness result, and 2 died of postoperative complications. Except for the completely resected cases, all the other patients underwent radiotherapy postoperatively. The results of this series show that microsurgical management of craniopharyngiomas yields good operative results.

We report a case of a seventy-year-old woman with syndrome of inappropriate secretion of antidiuretic hormone (SIADH) and adrenal insufficiency induced by Rathke's cleft cyst. She experienced nausea, vomiting, diarrhea, and headache and disturbance of consciousness induced by hyponatremia at a serum sodium level of 100 mEq/l. In spite of severe hyponatremia, urinary sodium excretion was not suppressed and serum osmolality (270 mOsm/kg) was lower than urine osmolality (304 mOsm/kg), and arginine vasopressin (AVP) remained within normal range. SIADH was diagnosed because she was free from other diseases known to cause hyponatremia such as dehydration, cardiac dysfunction, liver dysfunction, renal dysfunction, hypothyroidism, and adrenal insufficiency. Cranial computed tomographic (CT) scan and cranial magnetic resonance (MR) imaging showed a cystic lesion of approximately 2 cm in diameter in the pituitary gland. These images suggested that the cystic lesion was a Rathke's cleft cyst, which was the cause of SIADH. Water restriction therapy normalized her serum sodium concentration and improved her symptoms. After one year, she suffered from general fatigue, appetite loss, fever, and body weight loss (5 kg/2 months). She had neither hypotension nor hypoglycemia, but her serum sodium level was low and serum cortisol, ACTH, and urine free cortisol were very low. Therefore, secondary adrenal insufficiency was suspected and diagnosed by stimulation tests. After start of hydrocortisone replacement therapy (10 mg/day), her symptoms disappeared. In conclusion, Rathke's cleft cyst should be kept in mind as a potential cause in a patient with SIADH, hypopituitarism, and/or adrenal insufficiency.

Adrenal insufficiency combined with gastric ulcer due to herpes simplex virus (HSV) infection is a very unusual condition. A 75-year-old woman suffered from a 4-day history of poor appetite, constipation, dysuria, severe headache, generalized pain and malaise. Hyponatremia was noted. Escherichia coli infection was identified from urine culture. Poor pituitary-adrenal axis response to hyponatremia and infection, as well as a history of intermittent treatment with steroids, led to a diagnosis of iatrogenic tertiary adrenal insufficiency. During hospitalization, the patient passed tarry stools. In addition to an antral ulcer, panendoscopy revealed an ulcer in the gastric cardia with a clean base and irregular margins. Biopsy of the cardia demonstrated multinucleated giant cells in the stratified squamous epithelium. Polymerase chain reaction studies confirmed HSV type 1 infection. In patients suffering from gastric cardia ulcer, the possibility of herpes infection must be considered, especially when complicated by steroid treatment or misuse. Because herpes infection in the squamous epithelium is self-limiting, practitioners should be aware of it, so that overtreatment can be avoided.

Pituitary apoplexy during pregnancy is a rare but serious event with significant morbidity and even possible mortality if not recognised in time. A 26-year-old woman was admitted with sudden onset of severe headache, vomiting, disturbed consciousness and photophobia. MRI showed a pituitary apoplexy. Adrenal insufficiency with circulatory shock was present together with deficiency of the other hormones produced by the adenohypophysis. After treatment with glucocorticoids, diabetes insipidus developed for which treatment was given. She was treated conservatively and the clinical picture improved in a few days, followed by an uneventful pregnancy and delivery. A second MRI showed regression of mass effect with tumour expanding into the left cavernous sinus. No signs of tumour progression or abnormal hormone secretion have occurred up to one year after the event. Complete pituitary insufficiency has remained. The literature on the subject is reviewed with special emphasis on the circumstances in which pituitary apoplexy occurred and on the treatment of this endocrine emergency. In conclusion, pituitary apoplexy is a rare complication of pregnancy. The severe consequences of missing the diagnosis underline the importance of this potentially lethal endocrine emergency.

We review the clinical, hormonal and imaging features of 24 consecutive patients with symptomatic Rathke's cleft cysts (RCCs), and assess the long-term effectiveness and complications of transsphenoidal cyst removal. Out of 250 consecutive patients, 24 (10%) underwent endonasal transsphenoidal surgery for RCC; 19 (79%) were women. Symptoms at presentation included headaches (83%), hyperprolactinemia (38%), central hypothyroidism (21%), galactorrhea (13%), diabetes insipidus (13%), IGF-1 deficiency (13%), central adrenal insufficiency (8%) and visual loss (8%). In total, 37% of women had irregular menses and 60% of men sexual dysfunction and hypogonadism. Two girls presented with precocious puberty. Cyst size varied from 7 to 25 mm. Fifteen (60%) had a suprasellar component. Initial and 3-month post-operative imaging revealed complete cyst resection in 23 of 24 patients. Headaches resolved in 65% of subjects and visual loss resolved in both patients who presented with this symptom. Of those presenting with endocrinopathy, 56% had improvement of at least one anterior pituitary axis; two subjects (8%), both with suprasellar RCC, developed a new hormone deficiency post-operatively and two sujects young girls, (8%) had RCC recurrence, one at 36 months after surgery, requiring a second operation, and the other had a small asymptomatic recurrence 6 months after surgery. In conclusion, RCC accounts for 10 % of surgically treated sellar and suprasellar masses. Headache, hyperprolactinemia, menstrual irregularities and sexual dysfunction are common presenting symptoms. Simple cyst removal via a transsphenoidal approach offers a safe and effective treatment. Cyst recurrence may be more common in children.

A 67-year-old man first noticed loss of pubic and axillary hair in 1992 and then a visual field defect in 2001. He experienced loss of consciousness attributed to hyponatremia in April 2002. Magnetic resonance imaging showed a giant intrasellar cystic mass, 40 mm in diameter, that had compressed the optic chiasm. The patient complained of chronic headache, and neurological examination revealed bitemporal hemianopsia. Preoperative endocrinological examination indicated adrenal insufficiency, and hypothyroidism due to hypothalamic dysfunction. The patient underwent endonasal transsphenoidal surgery. The cyst membrane was opened and serous fluid was drained. Histological examination identified the excised cyst membrane as arachnoid membrane. The patient's headaches resolved postoperatively, but the bitemporal hemianopsia and endocrinological function were unchanged. This arachnoid cyst associated with hypothalamic dysfunction might have been caused by an inflammatory episode in the suprasellar region.

The aim of this study was to analyse the complete profile and outcome of patients with idiopathic giant cell granulomatous hypophysitis. Six consecutive cases of idiopathic giant cell granulomatous hypophysitis were studied from 1993 to 2002. Headache and visual disturbances were the most frequent presenting symptoms. All patients had hypogonadism, four had hypoadrenalism and three were hypothyroid at presentation. None of them had diabetes insipidus preoperatively. A sellar mass with suprasellar extension on MRI with loss of the posterior pituitary 'bright spot' was a consistent observation in all patients. All patients underwent surgical excision of the mass lesion with histopathological confirmation of giant cell granulomatous hypophysitis. Other systemic granulomatous diseases were excluded by appropriate investigations. Postoperatively, all patients became hypothyroid and hypogonad, five patients had adrenal insufficiency, while two developed permanent diabetes insipidus. The clinical presentation of giant cell granulomatous hypophysitis is that of an expanding sellar mass lesion with a varying degree of endocrine dysfunction. Preoperative diagnosis of 'hypophysitis' is usually difficult; however, stalk thickening and loss of posterior pituitary 'bright spot' on MR imaging are clues to the diagnosis.

Androgens are defined as the steroids having a binding affinity of the androgen receptor. In the reproduction age a daily production of testosterone is equally divided between the ovaries and adrenal and local tissue conversion of androstenedione and DHEA. After menopause the 80% of testosterone is produced in ovaries, but majority of precursors for peripheral conversion is adrenal origin. Androgen receptors are present throughout in the body; over 200 cellular actions of androgens have been described. Androgenic action is determined by quantitative level of the androgen present in the circulation, its degree of binding to proteins, the degree of interconversion to other androgens and estrogens, and the biological potency and androgen receptor binding affinity of the androgen. The most common clinical symptoms of androgen deficiency are the reduction of sex motivation, sex fantasy, sex enjoyment, sex arousal, vaginal vasocongestion, but also reduction of pubic hair, bone mass, muscle mass, worsening of quality of life (mood, affect, energy), more frequent vasomotors symptoms, insomnia, depression, headache. All these signs and symptoms can be multifactorial. Most common conditions associated with hypoandrogenism in women are hypothalamic-pituitary abnormalities, lack or insufficiency of ovaries, adrenal insufficiency, glucocorticoid therapy, exogenous estrogen administration. Besides the clinical picture the free testosterone measuring is important for diagnosis. The method of choice of this measure is equilibrium dialysis assay. Despite of clinical importance of androgen insufficiency in women, none of methods of androgen substitution is approved by FDA.

A 14-year-old female with perinatally acquired HIV on boosted protease inhibitor (PI) therapy with atazanavir and ritonavir rapidly developed cushingoid features with excessive weight gain and moon facies within 2 weeks of receiving inhaled fluticasone/salmeterol for asthma treatment. Soon after discontinuing PIs and inhaled steroid, she required hospitalization for dyspnea, headache, muscle weakness, and extreme fatigue requiring hydrocortisone replacement therapy for presumed adrenal insufficiency. Cushing syndrome and adrenal suppression were very likely caused by elevated steroid systemic concentrations resulting from the cytochrome p450 interaction between the protease inhibitors and fluticasone. The Naranjo probability scale score of 5 suggests that the event was probably drug related. This is the first case report of fluticasone and PI-induced Cushing syndrome and adrenal suppression in a pediatric patient without a history of recent or concomitant treatment with systemic steroid therapy. Additionally, this case is unique as it is the most rapid (<2 weeks) presentation documented, thus far. Health care professionals should be conscious of this important drug-drug interaction in HIV-infected children and adolescents and be aware that rapid onset of hypercortisolism and adrenal suppression are possible.
