Schwannomas are benign neoplasms arising from the sheath of myelinated nerve fibers and may occur in any part of the body. They mostly occur in the head and neck region, accounting for about 25% to 45% of all cases. The eighth cranial nerve is the most common site of origin. About 4% of all head and neck schwannomas originate in the nasal cavity and paranasal sinuses. The best treatment of schwannomas is surgical excision. Since it is an encapsulated tumor, difficultly is rarely encountered in its complete removal, and recurrence is unlikely. We present a unique and rare case of a 71-year-old man with a recurrent septal mass, finally diagnosed as a schwannoma, with a review of the literature.

While ancient schwannoma (AS) from the cervical sympathetic chain is very rare. Preoperative Horner's syndrome resulting from cervical sympathetic chain schwannoma (CSCS) is extremely rare. A 58-year-old woman visited our clinic with a huge lateral neck mass that had been present for thirteen years. Ptosis and enophthalmos were observed on the left eye. After radiologic evaluation, we assessed the CSCS by performing surgical excision. Finally, pathologic examination revealed it to be AS. There has been no recurrence for 15 months after discharge, however Horner's syndrome has become more prominent. We report this unique case of ancient schwannoma with literature review.

In most cases, skull base osteomyelitis arises from infections of external auditory canal, middle ear or paranasal sinuses. On the other hand, atypical or central skull base osteomyelitis has no evidence of external otitis or other infection sources. It is often found located on clivus and involves lower cranial nerves and brainstem through the foramina of skull base. The overall rate of mortality reaches 10% and long-term neurologic sequelae are seen in additional 31% of cases regardless of aggressive treatment. We recently encountered a 68-year-old man with right facial pain and generalized headache, and we achieved good outcome with the recovery of vocal cord palsy and disappearance of headache by surgical debridement and long-term antibiotics. We report it with a review of literature.

The laryngeal granuloma (LG) is non-neoplastic lesion that mainly develops in the posterior vocal folds. It is welknown that mis- or overuse of voice, habitual coughing, and endotracheal intubation can become the cause of LG. The laryngopharyngeal reflux also comes into the spotlight as an etiologic factor. Although LG has a tendency to recur easily, it is not a premalignant lesion. The co-existence with granuloma and laryngeal cancer has not been reported earlier. Recently, we encountered a 72-year-old man with a posterior glottic mass, which was diagnosed as squamous cell carcinoma coexisting with granuloma. To our knowledge, this is a first report on two coexisting carcinomas in the glottis.

Mucosa-associated lymphoid tissue (MALT) lymphoma, known as a distinctive type of non-Hodgkin's lymphoma, is an extranodal marginal zone B-cell lymphoma. It most frequently occurs in the stomach but has also been described in various non-gastrointestinal lesions, such as the salivary glands, conjunctiva, thyroid, orbit, lung, breast, kidney, liver, and prostate etc. It occurs very rarely in buccal mucosa. The MALT lymphoma tends to remain localized for long periods and respond to locally direct therapy. We recently encountered an 80-year-old male presenting with a foreign body sensation in the oral cavity; he was finally diagnosed as MALT lymphoma. We report this rare and unique case with a review of literature.

Mucocele of the appendix is basically a cystic dilatation of the appendix distal to an obstruction of the appendiceal lumen. It develops in unusual situations in which the distal lumen does not contain enough bacteria to initiate appendicitis when obstruction develops. The continuing mucous secretion causes gradual distention of the appendix and thinning of the wall until mucous secretion stops. The changes after the sudden blocking of the lumen of the appendix depend on the amount and character of the content distal to the obstruction. If the lumen is empty, the appendix distends with mucus to form a mucocele. Here we report a case which we experienced a 68-years-old female patient whose vermiform appendix had mucoceles with appendiceal intussusception.

PURPOSE: To determine the hepatic and vascular enhancement profiles with nonionic dimeric, iodixanol, contrast agent in the rabbit and to compare them with nonionic monomeric, ioversol, contrast agent. MATERIALS AND METHODS: Seven rabbits initially underwent hepatic dynamic CT scan with either iodixanol or ioversol, followed by repeated CT scan with other unused contrast agent with one week interval between scans. Pre and post contrast attenuation values of hepatic parenchyma, aorta and portal vein were measured sequentially. The mean enhancement of the hepatic parenchyma, aorta and portal vein were compared between two agents. The mean peak enhancement and peak enhancement time of the liver, aorta, and portal vein were also compared. RESULTS: The attenuation values of ioversol showed a greater mean hepatic enhancement than iodixanol from 18 seconds to 39 seconds after injection (from late arterial phase to early portal venous phase) with a statistical significance (p<0.05). The mean peak enhancement of hepatic parenchyma, aorta and portal vein was also greater using ioversol than iodixanol, but the mean peak enhancement times of ioversol and iodixanol were nearly identical. CONCLUSION: Ioversol may have the greater effects than iodixanol on hepatic tumor conspicuity, especially from late arterial phase to early portal veneous phase.

Salmonellosis is one of communicable disease and still occur in sporadic in Korea frequently. They are four main clinical manifestations in salmonellosis. They are gastroenteritis, typhoidal or septisemia syndrome, focal manifestation and carrier state. Among them, focal manifestation is rarely seen. Saphra, et al. reported that localized salmonella infection is about 5%. Localized salmonella infection frequently occur during salmonella bacteremia, but may also occur with enteric fever or gastroenteritis. Gray, et al reported 3390 cases of minor gunshot wound infection that bacterial isolates from infected wounds consisted of Staphylococcus aureus(90%), Streptococcus sp.(6%), and mixed organisms(4%). Incresed host susceptibility to infection secondary to lowered resistance due to debilitating disease is an important determinant of Salmonella infection. Since salmonella is seldom suspected as a cause of soft tissue infections,there is usually a dangerous delay in the institution of appropriate antimicrobial therapy and isolation procedure. We experienced one case of subcutaneous salmonella abscess developed on gunshot wound area in lung cancer patient, which was confirmed by pus culture.

PURPOSE: To evaluate the feasibility and usefulness of the transradial approach for intra-arterial chemoembolization therapy in patients with hepatocellular carcinomas. MATERIALS AND METHODS: Twenty-nine patients with hepatocellular carcinoma who underwent intra-arterial chemoembolization via the radial artery approach were involved in this study. All underwent Allen's test to check ulnar arterial patency. In all cases, we used the radial approach hepatic artery (RHA) catheter designed by ourselves, evaluating the selection ability of the hepatic artery using an RHA cathter, the number of punctures, the procedure time, and compression time at the puncture site as well as complications occurring during and after the procedure. RESULTS: Except for three in which puncture failure, brachial artery variation or hepatic artery variation occurred, all procedures were successful. The mean number of punctures was 3.5, and the average duration of the whole procedure was one and half hours. This gradually decreased as the number of procedures increased. The average duration at a compression of puncture site was 12 minutes. There were no major complications. Minor complications included minimal intimal dissection of the radial artery (3.8%), reversible vasospasm of the radial artery (7.7%), hematoma at a puncture site (7.7%) and transient neurologic deficit (3.8%). CONCLUSION: The transradial approach using an RHA catheter for intra-arterial chemoembolization therapy in patients with hepatocellular carcinomas was technically feasible, with acceptable levels of safety. It may be a good alternative to absolute bed rest with a sand bag after the femoral approach.
