We report a rare case of thyroid metastasis from early gastric cancer with lymph node metastasis in a 63-yr old woman. She was diagnosed with metastatic adenocarcinoma one and a half years after distal subtotal gastrectomy, by fine needle aspiration (FNA) using thyroid sonography. Thyroid metastasis from gastric cancer is extremely rare, and this case is particular in that it is the first report of thyroid metastasis from early gastric cancer.

Delayed-onset continuous bruxism due to brain stem infarction has not yet been reported. A 49-year old man presented with quadriplegia and ophthalmoplegia. Brain MRI showed acute infarction in the bilateral midbrain, right thalamus and the superior cerebellum. One month later, the patient developed bruxism which persisted during sleep. A palatal myoclonus was not observed. Follow up MRI taken 4 months later showed bilateral olivary hypertrophy. We suggest that the patient's bruxism may be related to the olivary hypertrophy. The bruxism generator may be located in the pontine-reticular-formation (PRF). Bilateral large midbrain lesions interrupting the cortical inhibition may have produced bilateral olivary hypertrophy, which could stimulate the PRF, producing continuous bruxism.

A 34-year-old male patient was first admitted to our Department on October 16, 1965. He complained of frontal headaches especially in the morning and ild right hemiparesis over the previous 6 months, which were progressively more severe as time went by. On examination, he was mentally clear ut slightly dysphasic: there were mild right hemisparesis and marked bilateral papilledema. Angiogram showed a left posterior frontal vascular tumor. At operation on November 3, 1965, total excision of a posterior frontal parasagittal tumor was performed. To the naked eye, this seemed to be a meningioma; the tumor was egg-sized, round but somewhat lobulated, graysish white in color, firm and fibrotic appearance, and it attached to the superior longitudinal sinus, involving without occluding it. Histologically. It was considered a meningioma of firbrolastic type, containing small amount of capillaries and some areas of collegen deposition around the fibroblasitc cell masses with foci of meningoendothelial cluster; though some doubt was expressed over its innocence. He tolerated the resection of frontal tumor well, and remained in relatively good health for 7 years, as to do his usual farmer work with minimal right hemiparesis. There were some episodes of generalized seizure during there periods. The patients was readmitted on December 25, 1972, however, because of frontal headaches and vomiting over recent 6 months and dysphasia, mental confusion developing rapidly over the previous 3 months. Urinary incontinence was also complained of. On examination he was drowsy, apathetic and mentally confused, more so than when first admitted. There was a goose-egg sized tense bulging in the left frontotemporal region, previously operated. Central-typed right facial palsy, right hypoglossal palsy and bilateral marked papilledema were noted. There were spastic hemiparesis, greater in the upper extremity, and long tract signs on the right side. Angiogram revealed a posterior frontal parasagittal vascular tumor, much as before. At operation on January 5, 1973, subtotal resection of tumor was performed, remaining the deep-seated parasagittal posterior frontal mass. The gross appearance of tumor was necrotic partially on the surfaces, potato-shaped with nodularith and pinkish white in color. On sectioning cut surface was slightly myxoid with cystic degeneration in the center. There was also patchy degeneration, showing yellow tinge in the cut surface. Microscopically, there were prominent hypercellularity with many mitoses, atypism, pleomorphism and degenerative process. Vascutar reaction with amyloid-like infiltration in perivascular area was also demonstrated as with focal pseudocartilagenous degeneration and partial hemorrhage; overall findings were highly suggestive of recurrent memingioma with malignant change (sarcomatous change) in left posterior frontal parasagittal region.

Trigeminal neurinoma is a rare condition arising from the gasserian or trigeminal nerve root. It comprises 0.2% of all brain tumors, and usually affects middle life, but about 10% of it appears in adolescents. Middle fossa syndrome, symptoms and signs of cerebellopontine angle tumor and mixture of these may be developed through the extension of the tumor. Symptoms and signs of cerebellar and midbrain compression may also be elicited in some stage of the tumor. Erosion of the Anteromedial portion of the petrous apex and defect of the flow of the middle fossa contribute to the diagnosis. Air studies and cerebral antiography have been used, and recently pantopaque basal cisternography has been introduced. The route of operation depends upon the main localization of the tumor, but transtemporal approach with tentorial section is widely used for dumbbell-shaped tumor. A case of cerebellopontine angle tumor which had been postoperatively proved to be a trigeminal neurinoma is reported.

Dystrophic calcifications themselves in the breast are classified as typically benign according to the Breast Imaging Reporting and Data System. However, we experienced a patient with invasive ductal carcinoma surrounding large dystrophic calcifications that could be regarded as long-standing benign conditions such as fat necrosis or hematoma. A 61-year-old woman presented with two large dystrophic calcifications within an irregular mass in the right upper outer breast on mammography. Ultrasonography revealed an irregular mass with dense calcifications showing strong posterior acoustic shadowing. On contrast enhanced magnetic resonance imaging, an irregular mass showed a persistent enhancement pattern and high signal intensity on a diffusion weighted image with non-enhancing areas corresponding to the calcifications. No abnormal uptake was observed on Tc-99m methylene diphosphonate bone scan. Invasive ductal carcinoma was observed on ultrasonography-guided core needle biopsy. In this case, we conclude that typical dystrophic calcifications within a breast mass cannot guarantee a benign diagnosis if the imaging characteristics of the mass are suspicious.

BACKGROUND AND OBJECTIVES: Sudden deafness in the elderly is rare and its prognosis is poorer than in adults. The unaffected ear also may have hearing impairment of variable severity and physiological hearing threshold shift termed presbycusis in the elderly. The old person often had various systemic complications including diabetes and hypertension. This study was designed to evaluate clinical manifestations and prognosis of sudden deafness in the elderly and to compare with sudden deafness in adults and children. SUBJECTS AND METHOD: We reviewed the medical and audiological records of 96 patients (102 ears) who are more than 60 years of age, and admitted to the Department of Otolaryngology, Pusan National University Hospital from January 1990 to December 2001. RESULTS: The total recovery rate of sudden deafness was lower in the elderly than in adults and children. Hearing recovery was significantly poorer in the patients with diabetes and hypertension. Hearing recovery was significantly poor in the patients with profound degree of hearing loss. The patients who had been treated within 7 days after onset of hearing loss showed better recovery rate than those treated 7 days later. CONCLUSION: We consider the effect of treatment of sudden deafness in the elderly to be best judged in various degrees of hearing impairment in the unaffected ear. The poor prognosis observed in patients with the concurrent disease is likely to have been brought about by preexisting microvascular diseases of the hearing organ, which is highly affected by aging. Good hearing recovery in the elderly is considered to be associated with time of initial treatment and expected in patients without concurrent diseases.

PURPOSE: The purpose of this study was to evaluate the anti-tumoral effect of recombinant vaccinia virus (rVV) (Thymidine kinase (-)/GM-CSF (+)) that was administered as a US guided intratumoral injection in a rabbit model of hepatic VX2 carcinoma. MATERIALS AND METHODS: VX2 carcinoma was implanted in the livers of 12 rabbits. US was performed at every week interval to detect hepatic mass after the implantation of VX2 carcinoma. The accurate tumor size and volume was evaluated with CT when the tumor was detected on US. US guided injection of rVV (109 pfu/ml) was preformed in three rabbits, intravenous injection of the same dose of rVV was done in two rabbits and another seven rabbits that were without any treatment were selected as a control group. We evaluated the change of the hepatic tumor size and extrahepatic metastasis on serial CT. Tumor specimens were harvested from rabbits that were killed at 8 weeks after VX2 implantation. These tissues were histoimmuopathologically compared to each other (the virus injection group and the control group). The differences between these groups were statistically assessed with student t-tests. RESULTS: Tumor growth was significantly suppressed in the US guided injection group compared with the intravenous injection group or the control group (p< 0.01). The intravenous injection group showed statistically significant tumor suppression compared to the control group (p< 0.01) until 2 weeks after virus injection. Quantification of the pulmonary metastatic nodules was performed in view of both the number and volume. The average number or volume of the pulmonary metastatic nodules in the US injection group was much smaller than these in the control group. Histopathologically, the tumors of the US guided injection group showed less extensive necrosis than those of the control group. Immunohistochemically, the tumor of the US guided injection group showed more prominent infiltration of CD4 (+) and CD8 (+) lymphocytes than did the tumors of the other group. CONCLUSION: rVV was markedly effective in suppressing hepatic tumor growth and extrahepatic metastasis in a rabbit model of hepatic VX2 carcinoma. US guided intra-tumoral injection was more effective than systemic intravenous injection.
