Adenoid cystic carcinoma is an uncommon tumor, especially in cases of its extension into the cranial cavity. Two cases of this tumor involving Gasserian ganglion were reported. The first case was a 47 year old female who developed paresis of the right side fifth cranial nerve. The plain skull X-ray of the axial view demonstrated enlargement of the right sided foramen ovale. The tumor was removed exploring the middle fossa extradurally, however its extention through the foramen ovale remained behind. A small induration was found at the base of the oral cavity postoperatively, and the biopsy revealed characteristic findings of adenoid cystic carcinoma histologically. Radiation therapy was followed by considerable clinical improvement.

The authors review the etiological, and therapeutic data obtained from a statistical study of a homogenous group of 50 patients after submandibular gland resections. The operation was conducted for calculi in the gland in 56% of cases, infections in 24% and for other causes in the few remaining cases, including 4% with glandular tumors. From the technical point of view, the two cutaneous approaches with section of the vessels and simple enucleation were able to be employed in 76% and 24% of the cases respectively; the ease with which cleavage was obtained being the main factor whatever the etiology. Wharton's duct must be systematically and completely removed when calculi are present. The indications for therapy can be summarized as follows: -- systematic operation on any suspicious tumor for which the etiology is not rapidly discovered, -- determining factors for operation are also infections, recurrences, and a posterior localization of the calculi, -- postoperative complications are minor and consist mainly of paresis of the VIIth cranial nerve, which always regressed in this series.

A metastatic seminoma of the right temporal fossa, with facial pain, extraocular paresis, otitis, and abdominal symptoms, was found in a 34-year-old man one year after orchidectomy for a primary testicular tumor that had been treated by surgery and radiotherapy. This is an unusual intracranial metastatic tumor that merits active treatment.

A rare case of mesenchymal chondrosarcoma originating from the thoracic spinal dura was reported. A 10-year-old girl complained of paresis of the right leg in June 1977. Then she became unable to walk early in August, and a complete paraparesis developed on August 18. She was admitted to our department on August 22. On admission she had complete paraparesis, bilateral ankle clonus, upward plantar reflexes, sensory disturbance below T7, shincter disturbance and neck stiffness. Plain thoracic X-ray revealed bilateral decalcification of pedicles of T6. Myodil myelography showed a complete block between T6 and lower end of T7 vertebrae. Bilateral laminectomy from T3 to T8 was performed. A tumor originating from the spinal dura was located in the right dorsal extradural space. The tumor was totally removed together with a small area of the affected dura. Light microscopy showed mesenchymal chondrosarcoma. Her recovery from neurological deficiencies was excellent and now she can run 14 months after surgery. Metastasis or recurrence has not yet been seen.

A diagnosis of vertebral multiple myeloma, based on radiographic evidence of osteolytic lesions and the finding of monoclonal paraprotein and large numbers of plasma cells in bone marrow biopsies, was made in a mature Doberman Pinscher. The abnormal serum paraprotein was a cryoglobulin of the immunoglobulin A class. Neurologic signs associated with the tumor included pain, progressive pelvic limb paresis, and paraplegia that developed during a 6-week period.

An ectopic muscle was found in the hypotympanum of a 31-year-old Japanese male. The muscle produced symptoms quite similar to those seen in cases of glomus jugulare tumor: a red mass visible through the ear drum, conductive deafness, a compressed jugular bulb demonstrable by retrograde jugulography, and VIIth and IXth nerve paresis. However, the audible pulsating tinnitus of glomus jugulare tumor was absent. The mass proved to be a muscle speculated as being a part of the levator veli palatini muscle. In view of our findings, ectopic muscle should be included in the differential diagnosis of glomus jugulare tumor.

Three cases of histologically verified neurinomas of the oculomotor nerve are reported. The preoperative diagnosis in all three cases was not made; on the contrary all cases were diagnosed as sphenoid ridge meningiomas. The oculomotor neurinoma manifests itself in the beginning with a discrete progressive palsy of the oculomotor nerve leading in later stages to complete ophthalmoplegia. Proceeding the oculomotor nerve paresis or going parallel to it is a functional loss of the homolateral optic nerve sometimes progressing to amaurosis. Unilateral exophthalmos as well as frontal or orbital neuralgic pain with or without sensory disorders in the area of trigeminus-I are characteristic for the clinical picture in later stages, all symptoms characteristic for the syndrome of the apex orbitae, resp. the superior orbital fissure, resp. the anterior cavernous sinus. The differential diagnosis has to consider above all the sphenoid ridge meningioma, the trigeminal neurinoma and the numerous tumors within the cavernous sinus (aneurysmas, meningiomas, chondromas, metastases of carcinomas, pituitary adenomas etc.) or the middle cranial fossa. Plain X-ray, carotid angiogram and computer tomogram are essential diagnostic means for localization and extension of the tumor but not for histological diagnosis. Oculomotor neurinomas are very seldom. The three observed cases did not have any relation to a possible generalized neurofibromatosis.

Eighth nerve specimens were removed during acoustic neuroma surgery, and findings were related to cochlear and especially to superior vestibular nerve function as studied by conventional caloric testing in 21 cases. The origin of the tumor was in eight cases the inferior and in two cases the superior vestibular nerve, and in eight cases the vestibular nerve without more specific localization. In three advanced cases the exact site of origin could not be determined. Leaving age-related changes out of account, the utricle and horizontal canal ampulla appeared normal in all ears except one in which the ampulla was replaced by tumor tissue. In 11 ears the superior vestibular nerve was histologically intact and three of these ears also showed normal caloric responses. In seven ears there was a canal paresis, and in three no reaction was obtained. The ten ears with partial or total nerve invasion by tumor either showed a weak reaction or no response at all. It is likely that an early conduction block arises in both cochlear and vestibular nerves, and reduced reactions to appropriate stimuli do not warrant conclusions that the numbers of anatomically intact nerve fibers possibly are reduced.

The paper reports on a 5 year old boy showing a sprawling haemangioma racemosum of the right side of the mediastinum. The vascular tumor is fed by a tortuous A. thoracica interna dextra and numerous arterial vessels arising from the right subclavian artery and from the aorta including the right coronary artery and branches from the abdominal aorta. The child presents also paresis of the right diaphragm probably secondary to the pressure of the pulsatile tumore along the course of the phrenic nerve. After ligation of three major feeding arteries the continuous murmur disappeared and fatigability and anorexia became less. Apart from this report a review of the literature on vascular malformations of the arterio-venous fistula type within the thorax sums up the most important features of these vascular anomalies: haemodynamics, localisation, clinical signs, therapy, natural history, therapy and etiology.

Report on a newborn with left-sided radial paresis due to a solitary angioleiomyoma in the lateral distal third of the upper arm. The literature does not disclose that this rare benign tumor can produce radial palsy. A palpable soft-part tumor in the new born suggests malignancy. The tumor including the atrophic radial nerve was radically excised. When histology proved it to be benign, a nerve graft with the sural nerve was carried out. After 6 months of electrical and physiotherapeutic treatment partial radial function had returned. In differential diagnosis of radial palsy of the neonate, birthtrauma is a likely cause. Tumors as a cause are rare and are found almost exclusively in adults, due to lipoma, neuroma or ganglia. In the neonate the socalled "idiopathic" radial paresis does not occur and in adults is usually due to the "supinator syndrome".
