A man of 74 years of age, suffering from a left-sided ophthalmoplegia and a radiologically detected opacification of the sphenoid sinus with destruction of the bony roof of the sphenoid sinus, was operated on because a malignant tumor was suspected. A destruction of the bony walls of the sphenoid sinus was found. The histological examination of the "glue"-like "tumorous" material revealed an aspergillosis. The patient developed an aspesrgillus meningitis postoperatively. Intrathecally administered Amphotericin B led to an improvement of the meningitis, but caused a fatal renal failure. A review of the literature showed that only 7 cases of aspergillosis of the sphenoid sinus have been reported, 3 of which presented with a tumor-like destruction of the sinus. An aspergilloma of the sphenoid sinus is therefore a rare but important differential diagnosis in patients with a suspected malignancy of the infrasellar region.

Acute exophthalmos and ophthalmoplegia of the left eye developed in a 58-year-old woman convalescing from a right hemicolectomy for a carcinoid tumor of the colon. Roentgenograms of the orbit and computed tomograms showed a large posterior left orbital mass. Lateral orbitotomy and biopsy confirmed the diagnosis of metastatic carcinoid tumor. Irradiation with radioactive cobalt (60Co) resulted in early relief of the ocular symptoms. To the best of our knowledge, this is the second documented case of orbital metastatic carcinoid tumor and the first patient with orbital involvement from a primary carcinoid tumor of the colon. Orbital irradiation for metastatic orbital carcinoid tumor has not been previously reported and should be used for symptomatic relief, because long-term survival is possible in patients with metastatic carcinoid tumors.

It appears that more than a hundred cases of trigeminal neurinomas have hitherto been reported, but massive extracranial extension of a benign neurinoma into the sphenoid sinus and soft part tissue of the neck is unusual. A 36-year-old woman was admitted to our clinic with complaints of left blindness, vertigo and left nasal stuffiness. Neuroradiological examinations, including plain craniography, angiography and CT, showed a huge mass which destroyed the left middle fossa and extended into the left sphenoid sinus and soft part tissue of the neck. On December 14, 1978, left fronto-temporal craniotomy was carried out, and intracranial portion of the tumor was removed, leaving its extracranial portion intact. Pathological examination revealed benign neurinoma. The postoperative course was uneventful except temporary left total ophthalmoplegia. It was emphasized that, to obtain cure for trigeminal neurinoma, early diagnosis is extremely important, and, for this purpose, CT, including coronal one, was considered to be one of the most useful examinations.

We describe the unusual association of two ocular motor abnormalities: upbeat nystagmus and internuclear ophthalmoplegia in a young woman originally believed to have demyelinating disease. Quantitative eye movement recordings documented a unidirectional defect in upward visual pursuit with preservation of the vertical vestibulo-ocular reflexes. The ocular oscillation was characterized as a type of "pursuit defect" nystagmus. An enhancing lesion of the upper brainstem seen on computerized tomography was primarily localized to the midbrain on pneumoencephalography. Biosy of the lesion disclosed a malignant glial tumor. The patient's course initally progressed but became stable following radiotherapy and chemotherapy during the next eight months. We believe the association of upbeat nystagmus and internuclear ophthalmoglegia should prompt a detailed search for a structural lesion.

In 1964, a 51-year-old man experienced a right abducens nerve palsy, which resolved spontaneously. In 1978, he developed painful ophthalmoplegia on the right with paresis of the right oculomotor and trigeminal nerves. Neuroradiographic evaluation was reported unremarkable, and the painful ophthalmoplegia was attributed to the Tolosa-Hunt syndrome. High-dose corticosteroids were administered with transient improvement of signs and symptoms. In 1979, cranial computerized tomography demonstrated a low-density lesion adjacent to the right cavernous sinus, which at operation proved to be an epidermoid tumor.

A 49-year-old woman with multiple sclerosis diagnosed by her classical clinical history and bilateral internuclear ophthalmoplegia was found to have an epidermoid tumor of the fourth ventricle. Removal of the tumor resulted in resolution of her neurological symptoms and signs.

Progressive, painful ophthalmoplegia developed in a 34-year-old man. MRI scan revealed an enhancing mass in the left cavernous sinus. Histologic examination of resected tumor revealed reticulin staining and cytologic features of hemangiopericytoma. Characteristics of intracranial hemangiopericytoma are reviewed.

A prospective study was conducted to evaluate the usefulness and limitations of conservative treatment in patients with pituitary apoplexy. Twelve patients presenting sudden headache, visual impairment, or ophthalmoplegia had the diagnosis of pituitary apoplexy established by computerized tomographic scans. Initially, 11 patients received iv dexamethasone (2.0-16.0 mg/day). Surgery was indicated when dexamethasone failed to improve visual or consciousness impairment. Among the 7 patients who were treated conservatively, ophthalmoplegia recovered completely in 6 and improved in 1. Follow-up computerized tomographic scans showed resolution of the tumor in 4 patients and residual masses in 3 patients who were treated conservatively. Five patients had surgery and experienced improvement of vision and consciousness. Follow-up computerized tomographic scans showed residual masses in all surgical patients. Recurrences were observed in 2 patients, one in each group. The prevalence of pituitary deficiencies in the conservative group (9 of 17) was similar to that of the surgical group (3 of 14), but when only patients whose tumors were resolved by the apoplexy were analyzed, a significantly higher prevalence (8 of 12) was observed (P = 0.02). A retrospective analysis of presenting clinical and computerized tomography data on the basis of the response to dexamethasone showed that visual impairment did not improve during treatment with dexamethasone, whereas the presence of a large hypodense area within the tumor predicted complete tumor resolution. These results support conservative management of pituitary apoplexy in patients who are selected on the basis of clinical and tomographic findings.

Pituitary apoplexy is a rare but sometimes dramatic complication of pituitary tumors. We report the case of a 64-year-old man with a macroadenoma who complained of a sudden and intense headache after a dynamic TRH (200 micrograms) and GnRH (100 micrograms) test. Two days later, he presented an acute ophthalmoplegia with fever and deteriorating consciousness. Emergency CT scan showed contrast hypofixation compatible with necrosis of the adenoma. Surgical, tumoral decompression resolved quickly almost all symptoms. Immunohistochemical study of the tumor confirmed the diagnosis of gonadotropinoma. Several similar cases of pituitary apoplexy occurring after TRH or GnRH tests have been described the last ten years. As this test may sometimes confirm the diagnosis of gonadotropinoma, it should be performed with caution in cases of clinically non functioning pituitary macroadenoma.

A 3-year-old boy presented with uniocular proptosis and ophthalmoplegia. Investigation revealed a mass involving the right orbit with extension into the left orbit and paranasal sinuses, and intracranial extension involving both frontal lobes. Biopsy of an enlarged cervical node and the intranasal mass revealed esthesioneuroblastoma. This tumor has been reported rarely in a child this age, and only 12 case reports document patients under 10 years of age. The presentation as an orbital mass is previously unreported and must now be considered in the differential diagnosis of proptosis in childhood. The usual clinical, radiological, and pathological features of olfactory esthesioneuroblastoma are reviewed.
