1/374. Pituitary macroadenoma manifesting as an isolated fourth nerve palsy.

    PURPOSE: To describe an unusual ophthalmic manifestation of a pituitary adenoma. methods: Case report. RESULTS: A 32-year-old man had left supraorbital and frontal headaches and new-onset vertical diplopia. Examination showed a left fourth nerve palsy and increased vertical fusional amplitudes. magnetic resonance imaging disclosed a sellar mass consistent with a pituitary macroadenoma. CONCLUSION: A pituitary adenoma may rarely manifest with an isolated fourth nerve palsy.

2/374. A huge pancreatic cystic adenoma misdiagnosed as an ovarian cyst.

    pancreatic cyst mimicking an ovarian cyst ultrasonographically has not yet been reported. We report an elderly woman with such a huge pancreatic cyst whose initial presentation was low abdominal pain. Ultrasound showed a hypoechoic cyst measuring 13.6 x 13.2 x 11.8 cm occupying pelvic cavity. She received laparotomy under the impression of ovarian cyst. Interestingly, the cyst was found to have originated from the pancreas. Total cyst excision was performed and pathologic report was pancreatic microadenoma. The patient's postoperative course was unremarkable.

3/374. Median sternotomy for parathyroid adenoma.

    Most mediastinal parathyroid tumours lie within the thymus gland and may be retrieved when cervical thymectomy is carried out in the course of neck exploration for primary hyperparathyroidism (HPT). We report 4 patients, each of whom required sternotomy for removal of a true mediastinal parathyroid adenoma. Subtraction isotope scintigraphy suggested the presence of a mediastinal tumour prior to cervical exploration in 2 individuals and prior to re-exploration in a third. When localisation before initial exploration for HPT suggests a parathyroid tumour within the chest, consideration should be given to proceeding to sternotomy, at first operation if a comprehensive neck exploration, including cervical thymectomy, fails to uncover the adenoma. Uniquely, one of our patients underwent sternotomy for HPT when 23 weeks pregnant.

4/374. Multiple canalicular adenomas: a case report and review of the literature.

    The canalicular adenoma is an uncommon, benign salivary gland tumor that most frequently occurs in the upper lip. Rarely, it manifests itself clinically and histologically as a multifocal lesion, a feature not generally seen with other intraoral salivary gland tumors. Here we report a case of canalicular adenoma that manifested itself with 13 clinically discrete tumor masses involving the upper lip and anterior buccal mucosa. In addition to the clinical nodules, there were microscopic foci of tumor cells in the adjacent normal-appearing salivary gland tissue surrounding the tumors. This article also reviews previously reported multifocal canalicular adenomas and discusses their features, emphasizing differences in the reported growth patterns of this unusual tumor.

5/374. A large intrathoracic parathyroid adenoma.

    A case is described in which an unusually large parathyroid adenoma was visible on the plain chest radiograph taken during the investigation of hypercalcaemia. This was diagnosed preoperatively and a scheme is suggested whereby such a disgnosis can now readily be made. The differential diagnosis is discussed ant the literature is reviewed.

6/374. Coexisting carcinoid tumors in familial adenomatous polyposis-associated upper intestinal adenomas.

    Upper gastrointestinal polyps and extraintestinal tumors are well recognized in association with familial adenomatous polyposis (FAP). Although carcinoid tumors have been reported in association with sporadic colonic neoplasms and ulcerative colitis, to date, carcinoids have not been reported in association with FAP. We report a patient with FAP who has recurrent carcinoid tumors located at the bases of duodenal adenomas. The genetic basis of carcinoid neoplasms is still uncertain. This report may represent the clinical effect of the APC gene mutation on the enterochromaffin cell line manifesting as recurrent carcinoid tumors in physical association with intestinal adenomas. Future genetic analysis and epidemiological studies may be of value in determining whether a true association exists.

7/374. Unusual MRI finding of multiple adenomas in the pituitary gland: a case report and review of the literature.

    The simultaneous occurrence of multiple adenomas in the pituitary gland is a rare event. We report the coexistence of three non functioning pituitary microadenomas in a 37-year-old woman, referred to us for oligomenorrhea and headache. Biochemical evaluation revealed prolactin (131 U/liters), follicle-stimulating hormone (4.1 U/liters), luteinizing hormone (3.9 U/liters), 17beta-estradiol (74 pg/mL), free (2.0 pg/mL) and total testosterone (0.5 ng/mL), dehydroepiandrosterone-sulfate (3.5 microg/mL), 17OH-progesterone (0.8 ng/mL), cortisol (13.1 microg/dL), free triiodothyronine (4.8 pmol/L), free thyroxine (18.5 pmol/liters), thyrotropin (1.6 mU/L), and growth hormone (0.2 ng/mL) levels in the normal range, as for as the response to dynamic endocrine tests. MRI showed an enlarged sella turcica, occupied by three distinct hypointense areas that measured less than 5 mm in diameter in the left, medium and right side of the pituitary, respectively. This finding was confirmed 6 months later by a second MRI that revealed also a light increase in microadenomas dimensions. The patient, therefore, underwent neurosurgery by transfenoidal approach. Histologic examination showed no morphologic differences between the specimens obtained from the different microadenomas. immunohistochemistry evaluation revealed a positive staining for the common alpha-subunit of glycoproteic hormones and negative for the other pituitary hormones tested, while electron microscopy showed cells with a poor secretory apparatus and a variable grade of cell differentiation. In conclusion, we report the fifth case described with multiple pituitary adenomas diagnosed in vivo and the first with three coexisting tumors revealed by MRI before neurosurgery. The occurrence of multiple pituitary tumors emphasizes the role of pituitary and extrahypophiseal factors in the clonal expansion of genetically altered cells.

8/374. Transsphenoidal microsurgical selective removal of multiple (triple) adenomas of the pituitary gland.

    This is the first case of multiple (triple) pituitary micro-adenomas documented by magnetic resonance imaging (MRI) in a living patient and treated by a transsphenoidal microsurgical approach. The patient, a 37-year-old woman, complained of a long history of bifrontal headache, weight gain and oligomenorrhea. physical examination revealed moderate hirsutism and a slight fat pad overlying the vertebrae. Routine laboratory studies and endocrinological biochemical investigations were normal. A gadolinium-enhanced MRI of the pituitary region revealed three intrapituitary micro-adenomas. A transsphenoidal microsurgical approach to the pituitary gland was carried out and micro-adenomas were completely removed one at a time. One year follow-up showed complete resolution of clinical symptoms and signs and normal biochemical parameters of pituitary function.

9/374. Clinics in diagnostic imaging (34). Invasive pituitary macroadenoma.

    A 44-year-old woman presenting with headache and decreased visual acuity was found to have bilateral papilloedema. Radiograph showed an enlarged pituitary fossa. MR scans demonstrated a large solid tumor with central necrosis, and both suprasellar and infrasellar extension. The invasive pituitary macroadenoma was surgically debulked, followed by radiotherapy. The clinical and imaging features of pituitary macroadenomas are discussed.

10/374. A review of heterotopia and associated salivary gland neoplasms of the head and neck.

    Salivary tissue neoplasms may involve normal, accessory and heterotopic salivary gland tissue. A case of Warthin's tumour originating from heterotopic salivary gland tissue of the upper neck is reported. The radioactive uptake of 131I, evidenced in the neck mass in its pre-diagnostic assessment, suggested a diagnosis of cervical node involvement from a primary malignant thyroid neoplasm. A critical review of the literature on heterotopic salivary gland tissue neoplasms of the head and neck is also presented.
