It is difficult to find the penetrating foreign bodies in the head and neck area only with history taking and physical examinations. One of the most important things is to detect the precise location of foreign bodies or possibly remained materials. The detection of wooden foreign bodies is important because they can cause phlegmon formation and because wood is often contaminated by Clostridium tetani bacteria. CT has proved to be an expedient method for detecting foreign bodies of various materials in soft tissues, but the wooden foreign body is often misinterpreted as a gas bubble in soft tissue. We have experienced a case of wooden foreign body which has penetrated through nasal dorsum and remained for 4 months. It had been initially misinterpreted as longstanding inflammatory lesion and osteitis of maxilla and nasal bone.

Usually fungal infections caused by opportunistic and pathogenic fungi had been an important cause of morbidity and mortality among immunocompromised patients. However clinical data and investigations for immunocompetent pathogenic fungal infections had been rare and neglected into clinical studies. Especially Cryptococcal brainstem abscess cases mimicking brain tumors were also much more rare. So we report this unusual case. This 47-year-old man presented with a history of progressively worsening headache and nausea for 1 month and several days of vomituritions before admission. Neurological and laboratory examinations performed demonstrated no abnormal findings. Previously he was healthy and did not have any significant medical illnesses. A CT and MRI scan revealed enhancing $1.8{\times}1.7{\times}2.0$ cm mass lesion in the left pons having central necrosis and peripheral edema compressing the fourth ventricle. And also positron emission tomogram scan demonstrated a hot uptake of fluoro-deoxy-glucose on the brainstem lesion without any evidences of systemic metastasis. Gross total mass resection was achieved with lateral suboccipital approach with neuronavigation system. Postoperatively he recovered without any neurological deficits. Pathologic report confirmed Cryptococcus neoformans and he was successively treated with antifungal medications. This is a previously unreported rare case of brainstem Cryptococcal abscess mimicking brain tumors in immunocompetent host without having any apparent typical meningeal symptoms and signs with resultant good neurosurgical recovery.

The authors diagnosed a 54-year-old male as central mucoepidennoid carcinoma after undergoing clinical, radiological and histopathological examinations. The characteristics were as followed : 1. Clinically, the patient complained of the painless unilateral swelling of the left mandibular molar region and had a pus discharge through the fistula. Painful nodule was palpated on the scalp of the left frontal area and it was regarded as a metastatic lesion. 2. Plain radiographs showed the ill-defined permeative radiolucent lesion. The osteolytic lesions were also detected in the cranial bone, number 9 and 11 ribs, scapula, and vertebral bodies. 3. The mandibular CT and PNS MRI showed the swelling of the left mandible and the enlargement of the several lymph nodes of 1.5 cm in size. 4. Histopathologically, many solid epidermoid type cells were mixed with mucus-secreting cells and they were arranged in duct-like structure. Most of them were epidermoid type, which indicates a high grade tumor. Mucins could be found in mucicamrine staining.

A cystic compound odontoma in the maxillary sinus occurred in a 13-year-old boy. who had missing right upper third molar without having the history of extraction of the wisdom tooth. He complained nasal stuffiness. headache. and pain on the affected face. resembling any sign and symptoms of the maxillary sinus problems. The cystic compound. sized 2 x 1.5 cm in diameter was pedunculated and attached on the posterior wall of the right maxillary sinus and above the antral floor. The location of the compound odontoma in the maxillary sinus was confirmed after panoramic. waters. spiral tomographic. CT examinations and surgical exploration. Its location was on the medial. posterior. superior to the normal position of the maxillary third molar or the maxillary dental arch. The cystic odontoma in the maxillary sinus made the patient have the signs and symptoms of maxillary sinusitis. The cystic compound odontoma might be originated from the dental lamina of the missing upper right third molar. The 'V principle' of the upper jaw growth and the pneumatization process of the maxillary sinus could explain why the compound odontoma had peduncular shape and the location of odontoma was on the medial. superior to the normal position of the maxillary dental arch.

Purpose: To assess the effect and safety of lobaplatin combinated floxuridine /pirarubicin in transcatheter hepatic arterial chemoembolization(TACE) of unresectable primary liver cancer. Patients and Methods: TACE combined with the chemotherapy regimen was used to treat 34 unresectable primary liver cancer patients. DSA/MRI/CT/blood routine examinations were used to evaluate short term activity and toxicity after 4-5 weeks, the process being repeated if necessary. Results: Among the 34 cases, 1 (2.9%) showed a complete response, 21 (61.7%) a partial response, 8 (23.5%) stable disease, and 4 progressive disease, with a total effective rate of 67.6%. The content of alpha fetoprotein dropped by over 50% in 20 cases (58.8%). The rate of recovery was hepatalgia (88.2%), ascites (47.1%), appetite (55.9%), Performance Status(30.4%). The median follow-up time (MFT) was 281 days (63-558 days), and median progression-free survival was 118.5 days (95%, CI:88.8-148.2days). Adverse reactions (III-IV grade) were not common, with only 4 cases of vomiting and 2 cases of thrombocytopenia (III grade). Conclusions: Lobaplatin-based TACE is an effective and safe treatment for primary liver cancer.

A 12-years-old Maltese (castrated male) dog with jaundice and purulent discharge from the shoulder was referred to the Veterinary Medical Teaching Hospital of Chungnam National University. A physical and laboratory examination revealed that the mucosa of the conjunctiva and the sclera were icteric, and the liver functional enzyme level and the total bilirubin level were increased. Duodenal caudal deviation caused by suspected masses in diameter of about 2 cm was shown by radiographic and ultrasonographic examinations. Using fine needle aspiration (FNA) and computed tomography (CT), the dog was diagnosed with alimentary lymphoma. The dog was treated with chemotherapy. Hematuria was discovered and dysuria occurred because of sterile hemorrhagic cystitis, which is a unique complication resulting from the use of cyclophosphamide.

We experienced a case of the papillary thyroid carcinoma seen as a huge solid lateral neck mass. The mass grew very slowly over the period of 30years up to 10cm in diameter while relatively well sparing the surrounding tissues. Physical examinations, CT scan, and fine needle aspiration cytology did not reveal any strong suggestions for evidence of malignancy. But it was pathologically diagnosed as metastatic thyroid carcinoma by excisional biopsy. We emphasize that for a large solitary neck mass which persists for several decades, head and neck surgeons should always keep in mind the possibility of metastasis from the malignancy of thyroid gland.

Purpose: Schwannoma is one of common neoplasm in the central and peripheral nervous systems. However, schwannoma of sciatic nerve is rare, especially large schwannoma arising in sciatic nerve is extremely rare. This is a report of our experience with large schwannoma arising in sciatic nerve with minimal neurologic symptoms. Methods: A 65 - year - old man presented with palpable mass in middle portion of posterior thigh. No definitive neurologic deficits were detected on physical examinations. CT and sonography showed well - defined mass with large dimension. The mass was excised and confirmed histologically as a schwannoma. In postoperative period, NCS and EMG were followed. Results: The patient complained of difficulty in dorsiflexion of ipsilateral ankle joint postoperatively. NCS and EMG obtained immediately and showed sciatic neuropathy. After 2 months postoperatively, NCS and EMG were followed and abnormal findings of previous NCS and EMG were not found. Dorsiflexion of ankle joint was improved to normal range of motion. Conclusion: We report a rare case of large schwannoma arising in sciatic nerve with no definitive neurologic symptoms.

Sleep related breathing disorders(SRBDs) are a group of diseases accompanied by difficulties in respiration and ventilation during sleep. Central sleep apnea, obstructive sleep apnea(OSA), sleep-related hypoventilation, and hypoxemia disorder are included in this disease entity. OSA is known to be the most common SRBDs and studies show its significant correlation with general health problems including hypertension, arrhythmia, diabetes, and metabolic syndrome. The diagnostic process of OSA is composed of physical examinations of the head and neck area and also the oral cavity. Radiologic studies including cephalography, CT, MRI, and fluoroscopy assist in identifying the site of obstruction. However, polysomnography(PSG) is still considered the gold standard for the diagnosis of OSA since it offers both qualitative and quantitative recording of the events during a whole night's sleep. The dentist who is trained in sleep medicine can easily identify patients with the risk of OSA starting from simple questions and screening questionnaires. Diagnosis is the first step to treatment and considering the high rate of under-diagnosis for OSA the dentist may play a substantial role in the diagnosis and treatment of OSA which will eventually lead to the well-being of the patient as a whole person. So the objective of this article is to assist dental professionals in gaining knowledge and insight of the diagnostic measures for OSA including PSG.

The cisterna chyli, a dilated lymphatic sac in the retrocrural space, is usually located to the right of the aorta. We report a case of a left-sided cisterna chyli, which was incidentally detected on the radiologic examinations of a preoperative workup for cholangiocarcinoma. Computed tomography (CT) and magnetic resonance (MR) images revealed a cisterna chyli measuring 2.5 cm in length in the left retrocrural space. The dilated lumbar lymphatics joined with the cisterna chyli, which was continuous with the left-sided thoracic duct. To the best of our knowledge, this is the second antemortem case of a left-sided cisterna chyli in literature. The cisterna chyli can mimic retrocrural lymphadenopathy, solid tumor with cystic degeneration, abscess or hematoma. The left-sided cisterna chyli should be referred to as a structure so as to be cautious in surgical approach.
