A rare case of falx meningioma with extensive vacuolization was reported. A 57-year-old woman was admitted to Okayama University Hospital because of
numbness
in her left lower limb. A plain CT scan showed a hypodense mass in the right frontal region with marked enhancement after contrast medium injection. MRI on T1 weighted images showed low intense mass with the so-called "peritumoral band" of low intensity at the periphery of the mass. Angiogram showed a mass effect and a
tumor
stain fed by the right pericallosal artery and left middle meningeal artery. The mass was excised en bloc. Microscopic examination demonstrated
tumor
cells with varied sized vacuoles, which were mostly fat-negative, except for small islands with typical meningothelial cells in the periphery of the
tumor
. Ultrastructurally, there were two kinds of vacuole in the
tumor
cells. The smaller, round vacuoles were in the cytoplasm, while the larger ones were in the extracellular space. The cell processes had developed junctional complex, and numerous cytoplasmic filaments were evident. With these findings, this mass was diagnosed as vacuolated meningioma. It is important especially in frozen section not to misdiagnose the
tumor
as liposarcoma, chordoma, metastatic brain tumor and so on.

Loss of sensation
in the lower lip is a common symptom. Frequently, it can be ascribed to orosurgical procedures carried out in the region of the inferior alveolar nerve or its mental branch. Additionally, trauma, haematoma or acute infections may be the cause of the problem.
Neoplasms
, an excess of endodontic paste and some drugs are less frequently responsible. Three patients are described, in whom impaired sensation in the lip was the presenting symptom. In two of the cases, local factors were found to which this complaint could be ascribed. Further investigation, however, revealed that disease elsewhere was the underlying cause.

Transcatheter arterial chemoinfusion and/or chemoembolization of the internal iliac artery have been used for the treatment of pelvic malignancies. Intraarterial chemoinfusion is expected to deliver a higher concentration of chemotherapeutic agents directly to the
neoplasm
, reducing the problems of systemic side effects. In 35 cases of pelvic malignancies, 61 procedures of intraarterial chemoinfusion and/or chemoembolization of cisplatin (CDDP) and/or adriamycin (ADR) were performed in combination with or without occlusion of the superior and/or inferior gluteal arteries by the use of steel coils. For chemoinfusion and chemoembolization, the anterior division of the internal iliac artery was selected. In 19 procedures of 14 cases, pain of the lower extremities and the hips developed soon after chemoinfusion and chemoembolization, and gradually followed by paresthesia. Each patient was complicated with
numbness
, dysesthesia and/or weariness of the lower extremities, thighs and the plantar and dorsal of the foot. These symptoms continued long without recovery. Additionally, the most severe complication such as paralysis and muscular atrophy of the unilateral lower limb occurred in one patient, and at the 14 months follow-up the patient was still suffering from paralysis and gait disturbance. A neurologic examination revealed damage of the sciatic nerve at the level of L5, S1 and S2. It was suggested that the cause of the neurologic complications was attributed to ischemia and/or to deliver a higher concentration of chemotherapeutic agents of the sciatic nerves, and that any previous surgery, radiotherapy or intraarterial chemoinfusion combined with embolization was not related to the symptoms under discussion.

Diethyldithiocarbamate (DDTC) has been shown to provide protection against most clinically significant toxic effects from cisplatin (DDP) without inhibiting
tumor
response in a variety of murine animal models. We conducted a phase I clinical and pharmacokinetic study of DDTC in combination with DDP to establish the types and severity of toxic effects and to determine whether protection of normal tissues and tumors occurs. Twenty-two courses of DDP plus DDTC were given to 10 patients. No nephrotoxic effects were seen at DDP doses of 50-120 mg/m2, and three patients had amelioration of nausea and vomiting. Objective antitumor responses were observed. Dose-limiting toxic effects from DDTC occurred at 150 mg/kg; these consisted of
numbness
in the infusion arm often accompanied by severe diaphoresis, chest discomfort, and agitation during DDTC infusion. These toxic effects resolved spontaneously, however, after termination of the infusion. The preliminary results suggest that plasma levels of DDTC that provide excellent protection in rodents were exceeded at the doses used in our clinical study without compromising antitumor response.

The case described is thought to be the first report of ulnar neuropathy caused by a cystic myxomatous degeneration of fat necrosis. The 12-day preoperative duration of symptoms is also the shortest reported for nontraumatic ulnar neuropathy; the average period between onset of symptoms and operation is 10 months. At operation, the patient's nerve was found to be stretched severely over the
tumor
, which was excised, thus decompressing the ulnar nerve. The procedure relieved the patient's symptoms of tingling and
numbness
, and he remained asymptomatic at the 12-month follow-up examination.

The cases of 28 patients with neoplastic spinal cord compression were reviewed. The most common presenting symptoms were: back pain (68%), bilateral leg weakness (61%), urinary retention (36%), and bilateral leg
numbness
(32%). Twelve patients (43%) had known
neoplastic disease
prior to diagnosis of spinal cord compression. Only two patients (7%) were diagnosed within one week of the onset of major spinal symptoms. The commonest symptoms associated with delay in diagnosis were again back pain (50%) and bilateral leg weakness (38%). However, when certain symptoms were present, diagnosis was almost always delayed, particularly with unilateral leg weakness or pain (100%), ataxic gait (80%), and back pain (68%). Symptoms in the neck, chest, and arms were also always associated with delayed diagnosis.

A case of spinal dumbbell shaped melanotic schwannoma was reported. A 58-year-old housewife had a 3-months history of progressive gait disturbance. She also complained of mild backache and
numbness
in both legs. Her family history was not remarkable. When examined on admission, October 10, 1982, mild weakness of both legs with spasticity and sensory impairment below the level of T10 dermatome without sacral sparing were evident. Her deep tendon reflexes were hyperactive on both sides and plantar responses were extensor bilaterally. Sphincteric disturbance was not significant. The function of her cranial nerves was intact. She had neither cutaneous lesions, abdominal mass nor organomegaly. Thoracic plain X-rays revealed erosion of the right side vertebral body and pedicle of the 10th thoracic vertebra. Myelography disclosed a complete block at the same level by an epidural mass. On CT-myelogram, soft tissue density mass compressing the thoracic cord was apparent in the right epidural space of the spinal canal which extended to the paravertebral region through the right intervertebral foramen. Partial destruction of the body and the right side pedicle was easily recognized. Laminectomy from T9 to T11 exposed a large extradural mass which was encapsulated, elastic soft and pigmented in nature. The
tumor
was dumbbell shaped and extended to the right paravertebral region through the intervertebral foramen. Costotransversectomy was performed to excise the mass entirely. Following the total removal of the
tumor
, internal fixation was carried out by means of Harrington instrumentation with methylmethacrylate.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of trigeminal neurinoma with marked extracranial extension is reported with a review of the literature. A 60-year-old female noticed
numbness
over the left side of the face during the proceeding 15 years. Two years prior to admission, she began to complain of itching and lancinating pain at the left lateral aspect of the nose. Neurologic examination on admission revealed diminished corneal reflex on the left side and hypesthesia in the distribution of the left trigeminal nerve. There was no weakness or atrophy of the ipsilateral masticatory muscles. The remaining cranial nerves and cerebellar functions were normal. Craniograms showed destruction of the left petrous apex, enlargement of the left superior orbital fissure and an extensive bone defect in the floor of the left middle cranial fossa. CT disclosed a huge heterogeneously enhancing mass lesion in the left middle cranial fossa, which extended posteriorly into the left cerebellopontine angle and inferiorly into the pterygoid and infratemporal fossae. Cerebral angiograms revealed medial displacement of the left internal cerebral artery in the ganglionic, cavernous and supraclinoid portions, and elevation of the left middle cerebral artery in the sphenoidal portion. Although the left meningohypophyseal trunk was dilated, no
tumor
stain was observed. A transantral biopsy specimen provided the diagnosis of neurinoma with Antoni type A tissue. The patient was followed up at the outpatient clinic as radical operations were not agreed upon. Eight cases of trigeminal neurinoma with extracranial extension are reviewed including the presented case. There were two males and six females, and the age varied from 16 to 65 years.(ABSTRACT TRUNCATED AT 250 WORDS)

A case of epidermoid carcinoma arising in an epidermoid cyst in the cerebellopontine angle is presented. Clinical features and CT appearance are discussed in comparison with those of benign epidermoid cyst. A 43-year-old man was admitted to the Department of Neurosurgery, University of Tokyo Hospital on April 14, 1983, with complaints of right facial
numbness
and weakness of six months' history. On neurological examination, sensation of the right half of the face was decreased in all modalities. Marked atrophy of the ipsilateral temporal muscle was also noted. Right facial paresis of peripheral type was evident. Gag reflex was decreased on the same side. Except for a slightly increased left deep tendon reflexes, there were no pyramidal tract signs. A CT without contrast material failed to show any abnormalities. A postcontrast CT demonstrated an irregular enhancement in the right cerebellopontine angle. The finding of asymmetry of the ambient cistern indicated minimum mass effect on the metrizamide CT cisternography. Suboccipital exploration of the right cerebellopontine angle was carried out on April 28, 1983. Leaving a part of the capsule indenting the pons between the roots of the fifth and the seventh nerve, we removed a white pearly
tumor
. Histological diagnosis was typical epidermoid cyst. He left the hospital one month later with signs of the right seventh and the eighth nerve. His postoperative course, however, was beyond our expectation. Over a few months following his discharge, left hemiparesis as well as horizontal and vertical nystagmus gradually developed. He was readmitted on November 10, 1983. A postcontrast CT revealed enlargement of the enhanced lesion filling the right ambient cistern.(ABSTRACT TRUNCATED AT 250 WORDS)

The purpose of this paper is to evaluate the short latency somatosensory evoked potentials (SSEP) in the diagnosis of cervical lesions. Recordings were obtained from 59 patients with cervical lesions which included 24 cases of cervical spondylosis, 4 cases of disc herniation, 14 cases of OPLL, 4 cases of intramedullary
tumor
, 7 cases of extramedullary
tumor
and 6 cases of syringomyelia. SSEP changes in these cases were classified into three major types as follows: type I; normal SSEP, type II; prolongation of interpeak latency, and type III; absence of the component of SSEP. Types II and III were subdivided into two subgroups, respectively, as follows: type IIa; prolongation of interpeak latency between P9 and P11, type IIb; prolongation of P11-P13, type IIIa; no responses after P11 and type IIIb; no responses after P13. Type I was detected in 25 cases (42%), type II in 16 cases (27%), and type III in 18 cases (31%). These SSEP findings were compared with clinicoradiological findings. In type I, the locations of the lesions confirmed by the radiological findings were variable, and there was no definite tendency in the localizations. 80% of type I showed only
numbness
of extremities or disturbance of the superficial sensations. The cervical lesion was located just under the C5 vertebral level in type IIa and IIIa, while the lesion was extended above the C4 vertebral level in type IIb and IIIb. These results were explained by the generation sites of P11 and P13 (P11 originated from the lower dorsal column, and P13 from nearby the dorsal column nucleus).(ABSTRACT TRUNCATED AT 250 WORDS)
