2/78. Suprasellar cystic germinoma.

    We report on a germinoma in the suprasellar region, which had multiple large cystic components. A 13-year-old girl with disturbed visual acuity and growth retardation was admitted to our hospital for treatment of an intracranial tumor. The lesion was difficult to diagnose as a germinoma preoperatively, because of its radiographic characteristics. Histopathological examination revealed that the tumor was a germinoma. Surgery, chemotherapy with carboplatin and etoposide, and radiotherapy (30 Gy) were successful in inducing complete remission of the tumor. The patient's endocrine status remained normal, except for a low GH concentration and diabetes insipidus.

3/78. Rosai-Dorfman disease presenting as a pituitary tumour.

    A 45-year-old woman had pyrexia, headaches, collapse and hyponatraemia. Intracerebral abscess, bacterial meningitis and subarachnoid haemorrhage were excluded. She was given intravenous antibiotics and gradually recovered. One month later she was readmitted with diplopia, headache and vomiting. serum sodium was low (107 mmol/l) and a diagnosis of inappropriate ADH secretion was made. MRI scan showed a suprasellar tumour arising from the posterior pituitary gland. A skin rash gradually faded. serum cortisol, prolactin, gonadotrophins and thyroid hormone levels were low. A pituitary tumour was removed trans-sphenoidally, she had external pituitary radiotherapy, and replacement hydrocortisone and thyroxine. She was well for 12 months when she developed progressive weakness and numbness of both legs. Examination suggested spinal cord compression at the level of T2 where MRI scanning showed an intradural enhancing mass. This spinal tumour was removed and her neurological symptoms disappeared. Nine months after this she developed facial pain and nasal obstruction. CT scan showed tumour growth into the sphenoid sinus and nasal cavities. A right Cauldwell-Luc operation was done and residual tumour in the nasal passages was treated by fractionated external radiotherapy and prednisolone. Histological examination of the specimens from pituitary, spinal mass, and nasal sinuses showed Rosai-Dorfman disease, a rare entity characterized by histiocytic proliferation, emperipolesis (lymphophagocytosis) and lymphadenopathy. aged 48 she developed cranial diabetes insipidus. Although Rosai-Dorfman syndrome is rare, it is being reported with increasing frequency, and should be borne in mind as a possible cause of a pituitary tumour.

4/78. Symptomatic Rathke's cleft cyst coexisting with central diabetes insipidus and hypophysitis: case report.

    We describe a 48-year-old female with acute onset of central diabetes insipidus followed by mild anterior pituitary dysfunction. magnetic resonance imaging (MRI) revealed enlargement of the hypophysis-infundibulum accompanied by a cystic component. She underwent a transsphenoidal exploration of the sella turcica. Histological examination showed foreign body type xanthogranulomatous inflammation in the neurohypophysis which might have been caused by rupture of a Rathke's cleft cyst. The MRI abnormalities and anterior pituitary dysfunction improved after a short course of corticosteroid administration, but the diabetes insipidus persisted. The histological findings in this case indicated the site of RCC rupture and the direction of the progression of RCC induced neurohypophysitis and adenohypophysitis.

5/78. MRI detection of suprasellar germinoma causing central diabetes insipidus.

    This is a case report of an 18-year-old man with central diabetes incipidus (DI). An MRI done three months after the onset of the DI did not disclose a responsible lesion. Four months later, a second MRI showed the location of the tumor origin at the upper pituitary stalk and median eminence. Eight months later, the tumor occupied the hypothalamic area. The tumor became large and contrast-making enough to be visible on MRI between 3 and 4 months after the onst of DI. Besides the suprasellar tumor, another mass was noted in the pineal region. The growth pattern of the latter mass corresponded well to that of the former. Although the MRI is a sensitive diagnostic tool for the detection of intracranial tumors, no adequate rationale has been given as to how the MRI might be repeated for children and adolescents who have been diagnosed as having the central DI, when their initial MRIs may have been normal. In our patient, the superconductive thin slice MRI revealed the suprasellar germinoma 4 months after the onset. The suprasellar and pineal tumors in this report originated and developed simultaneously. This may indicate a multi-center origin of the tumor. Another possibility is a very early dissemination from the onset of the tumor development.

6/78. Panhypopituitarism associated with diabetes insipidus in a girl with a suprasellar arachnoid cyst.

    We report on a female patient with a large suprasellar arachnoid cyst (3.5 x 2.5 cm) combined with right optic nerve hypoplasia. She developed growth hormone deficiency and hypothyroidism at the age of 8.5 years, adrenal insufficiency at the age of 11 years, diabetes insipidus and hypogonadotropic hypogonadism at the age of 15 years. When last seen at the age of 19 years she was extremely obese ( 5.9 BMI SDS). The endocrine picture suggests that arachnoid cysts might be involved in far more complex hypothalamic-pituitary disturbances than previously thought.

7/78. Pituitary insufficiency after penetrating injury to the sella turcica.

    We report a 28-year-old male patient with a pituitary insufficiency after a simple fracture of the sella turcica. He was injured by a long nail that punctured the lower jaw. No fracture other than that of the sella turcica was detected. An endocrinological examination revealed both anterior and pituitary dysfunction and diabetes insipidus that continued for about two months.

8/78. Transient diabetes insipidus and hypopituitarism after pituitary apoplexy: a rare association with pericardial effusion and painless thyroiditis.

    pituitary apoplexy in a 38-year-old male patient with acromegaly who presented with pericardial effusion, anterior pituitary dysfunction, and diabetes insipidus is described. With corticosteroid therapy, there was good initial recovery of pituitary function and regression of pericardial effusion. On withdrawal of corticosteroids, he developed painless thyroiditis, with transient thyrotoxicosis. Subsequently, the pituitary function tests remained normal for a year, but later he gradually developed hypogonadotropic hypogonadism, hypocortisolism, growth hormone deficiency, and progressive pituitary atrophy, resulting in empty sella syndrome.

9/78. From macroprolactinoma to concomitant ACTH-PRL hypersecretion with Cushing's disease.

    Multiple pituitary hormone hypersecretions have been already described, but the combination of PRL and ACTH excess is rare. This report deals with a 42-yr-old woman affected by macroprolactinoma (PRL 12,720 microg/l, huge tumor with extrasellar extension at imaging). After one year on dopaminergic treatment causing PRL normalization and tumor shrinkage, she developed hypercortisolism (UFC 1,000 microg/24 h, ACTH 200 ng/l). Cushing's disease was diagnosed. After neurosurgery (at immunocytochemistry mixed ACTH-PRL adenoma was shown) hypercortisolism remitted, whereas pathological hyperprolactinemia with tumor remnant in cavernous sinus persisted and hypopituitarism developed. The patient reported seems atypical for the following reasons: 1) the concomitant PRL and ACTH hypersecretions; 2) the clinical presentation with hypercortisolism following hyperprolactinemia; 3) the surgical cure of hypercortisolism with persisting hyperprolactinemia.

10/78. Pituitary metastasis from uterine cervical carcinoma: a case presenting as diabetes insipidus.

    The authors report a case of symptomatic pituitary metastasis from an adenocarcinoma of the uterine cervix. Only two cases of intrasellar metastasis from an adenocarcinoma of the uterine cervix have been previously reported; both were identified at autopsy. Our patient presented with clinical features of diabetes insipidus and a right sixth nerve palsy. Trans-sphenoidal surgery was performed and partial removal of the tumour was achieved. The tumour was an epidermoidal carcinoma of the uterine cervix located primarily in the posterior lobe of the pituitary. The patient's neurological symptoms were relieved following surgery. The possibility of a secondary location must always be considered in a differential diagnosis when treating an intrasellar lesion in a patient with a documented primary malignancy.
