This type of neuropathic pain(atypical odontalgia) is seen most often in middle-aged women or men after dentoalveolar operation. Atypical odontalgia probably is caused by deafferentation leading to intraneural changes in the medullary dorsal horn. Treatment of this problem is difficult, but some success has been reported in uncontrolled, open-labeled studies using high doses of tricyclic antidepressants. This is the management report of a patient case, that had a neuropathic atypical odontalgia recognized with the right maxillary lateral incisor. The patient was consulted to the Department of Pain Clinics, ENT & Neurology and diagnosed the adenoid cystic carcinoma on left cerebellum and right paranasal sinus with extension to the cavernous sinus. In spite of the osteoplastic craniotomy, neurosurgical mass removal and radiation therapy were done with chemotherapy, atypical odontalgia was continued. In addition to the consultation to Psychology, stress management and antidepressant medication were done and improved slowly.

Paraneoplastic limbic encephalitis, a remote effect of cancer without nervous system metastasis, is rare, especially in childhood. Here, we report a case of paraneoplastic limbic encephalitis associated with an ovarian mature teratoma in an adolescent girl. The 15-year-old girl developed neuropsychiatric symptoms, memory loss, seizures, and unconsciousness. Cerebrospinal fluid analysis and brain magnetic resonance imaging (MRI) findings were normal, while single photon emission computed tomography imaging showed hypoperfusion in both temporal lobes. Ultrasound and MRI of the abdomen revealed a left ovarian cystic mass. The patient experienced a significant recovery of cognitive function after surgical resection of the tumor, which was pathologically identified as a mature ovarian teratoma, and treatment with intravenous immunoglobulin.

Two female Yorkshire terrier was referred to Veterinary Medical Teaching Hospital, Seoul National University. In case 1, clinical signs were vomiting, anorexia and weight loss. Cystic intraabdominal mass was identified in radiographic and ultrasonographic examination. In case 2, clinical sign was abdominal distension. In radiographic and ultrasonographic examination, cellular ascites and bilateral intraabdominal masses next to kidneys were observed. Many clusters of glandular epithelial cells with anisocytosis, anisokaryosis, high N:C ratio coarse chromatin and prominent nucleoli were shown in cytologic examination of sanguineous ascites. In all two cases exploratory laparotomy was performed and enlarged ovaries were observed (Rt: 6$\times$5$\times$5 cm and Lt: 3$\times$2$\times$1 cm in case 1 and 3$\times$2$\times$1 cm bilaterally in case 2). After ovariohysterectomy histopathologic examinations were performed. Histopathologically the masses were diagnosed as ovarian adenocarcinoma and ovarian cystadenocarcinoma in case 1 and case 2, respectively. In both dogs no further chemotherapy was carried out. These two dogs had no gross evidence of tumor recurrence at the time of 3 months after tumor resection, but long-term follow-up might be needed.

Crossed renal ectopia is a congenital malformation in which both kidneys lie on the same side of the spine, usually side by side longitudinally. More often on the right side. Fusion of the two renal units is eight times more common than nonfusion. Although crossed renal ectopia is uncommon, this unusual entity must be considered in an infant when cystic mass in the abdomen or pelvis paticularly if no kidney can be found on the opposite side. In many cases of crossed fused ectopia with multicystic dysplastic kidney(MCDK), the diagnosis can be strongly suspected from the sonogram, and no other studies may be necessary. However, both intravenous urography and isotope renography is useful to assess the function of the crossed kidney. Crossed renal ectopia and MCDKs are associated with a greater incidence of ureteropelvic junction obstruction and reflux. So, screening voiding cystourethrography should be performed. Very few studies of MCDK in the setting of crossed fused ectopia have been reported. We have experienced a 3-year-old boy with crossed fused renal ectopia with multicystic dysplasia.

Intussusception is a frequent cause of bowel obstruction in the first five years of life and it is one of the most common surgical emergencies in infancy and early childhood. The age of five months child was administered in Department of Pediatrics of Chunchon Sacred Heart Hospital. His main symptoms were vomiting and high fever for three days. Abdominal sonography, air reduction and abdominal computerized tomography (CT) were performed and the conclusion of these study was intussusception due to cyst mass lesion; duplication cyst, mesenteric cyst or Meckel's diverticulum. He was transferred for operation. We had performed laparotomy for reduction of the intussusception. Operative findings revealed ileocolic type of intussusception due to cystic tumor on ileocecal valve that was invaginated into the cecum, and hyperplasia of the Peyer's patch were seen. But we failed manual reduction because of the tumor in the ileocecal area. So we had performed partial resection of the ileocecum. Diverticulum of the ileum was confirmed by pathologic examination. We experienced unusual cause of the intussusception. So we report this case with a review of the literatures.

One hundred fifty four cases of branchial anomaly treated from January 1987 to July 1993 were analysed to determine clinical features, embryologic and anatomic types of the branchial cleft anomaly, to investigate the differences between adults and pediatrics, and to establish the appropriate treatment plan. The male to female ratio was not signifiacntly different in pediatric and adult patients. The mean symptom duration was 0.5 years(range 0.08-14 years) in pediatric patients and 1.67 years (0.7-7 years) in adult patients. The clinical presentations of these anomalies were lateral neck mass in 112(72.7%), infected discharge in 22(14.3%), non-infected discharge in 6(3.9%), and abscess in 14 cases(9.l%). Sites of the lesions were upper third of the neck in 93(60.3%), infraauricular in 35(22.7%), middle third of the neck in 17(11.0%) and inferior third of the neck in 9 cases(5.8%). The anatomic types were cystic form in 117(75.9%), sinus in 24(15.5%), and fistula in 13 cases(8.4%). Embryologic classification were 124 second branchial cleft anomalies(80.5%), 29 first branchial cleft anomalies(18.8%), and 1 third branchial cleft anomaly(0.6%). Immediate surgery under the uncontrolled infection in 17 cases result in 82.4% recurrent rate(14 cases), and 17.6% cure rate(3 cases). Delayed surgery under the controlled infection in 8 cases recurrent rate(1 case), and 87.5% cure rate(7 cases). In summary, the most common branchial cleft anomaly is second type cyst both in pediatric and adult group, delayed surgical exterpation after infection control with I & D or antibiotics may give a good chance for care and may reduce the recurrence.

A 5-year-old, 2.7 kg female maltese dog was presented a local veterinary clinic with one week history of hindlimb lameness associated with patellar luxation. Reduction of bilateral medial patellar luxation was operated using trochlear resection and lateral reinforcement technique. Three weeks after the surgery, the dog showed bending spine with pain in thoracic and lumbar region, continuous ataxia and intermittent convulsion. Magnetic resonance imaging scanning revealed a hyperintense mass in right frontal lobe of brain and abnormal cavitation from cervical cord to third lumbar cord. Histopathologically, neoplasm in brain composed of meningothelial cells showed loosely reticular or lace-like morphology with numerous extracellular cystic spaces of variable size and shape. Neoplastic cells were positive for vimentin and negative for neuron specific enolase and glial fibrillary acidic protein. Irregular shaped enlarge central canal-like cavity was existed in cervical and lumbar cords. In our best knowledge, this report described the clinical findings, imaging and histopathologic characteristics of unusual intracranial microcystic meningioma with secondary syringomyelia in a dog.

We have experienced 50 cases of mediastinal tumors and cysts from March, 1979 to August, 1985 at Kyung Hee University Hospital. The results of this cases analysis were as followings; 1. Of all 50 mediastinal tumors and cysts, 26 patients were male and 24 patients were female. There was no sex preference. The age distribution was from 27 months to 64 years, and mean age was 33.5 years old, and also no age preference. 2. The most common mediastinal tumor was benign cysts [12 cases], which comprise 24% of all mediastinal tumors and cysts. The second common mediastinal tumor was teratoma [9 cases-18%], and followed by thymic tumors and tuberculous granuloma [7 cases-14% each], neurogenic tumors [5 cases-10%], and other tumors [10 cases-20%]. 3. The anterior mediastinum was most common tumor location, and followed by middle, superior, and posterior. 4. All 9 teratomas were developed at anterior mediastinum, and 4 of 5 neurogenic tumors were developed at posterior mediastinum. Thymomas were developed at anterior and superior mediastinum. The bronchogenic cysts had no predilection of location. 5. The most common chief complaint at admission was chest pain or discomfort [23 cases-46%], and followed by cough with or without sputum, and exertional dyspnea. Asymptomatic patients were only 7 patients [24%]. 6. Of all 50 cases, 38 cases [76%] received radical tumor resection, 7 mediastinoscopic biopsy, 3 explo thoracotomy and biopsy, and 1 neck mass biopsy. 7. There were 2 hospital deaths, one of which was a patient who suffered malignant thymoma and Myasthenia Gravis. The patient received radical tumor excision, but died at 7th POD. The other patient was a patient with malignant transformation of the benign cystic teratoma. The operative mortality was 4%.

Pulmonary artery aneurysms are extremely rare conditions usually associated with congenital cardiac defects that cause increased pulmonary blood flow and pulmonary hypertension. The prognosis of pulmonary artery aneurysms is fatal due to the potential for rupture of the aneurysm and the underlying severe pulmonary hypertension. A 40-year old woman was admitted to our hospital with headache following traffic accident. On admission a continuous murmur was heard over the 2nd to 3rd intercostal space along left sternal border and a calcified cystic mass at left hilar portion was incidentally discoverd on chest reontgenogram. Cardiac catherization was diagnostic of a left to right shunt at main pulmoanry artery level and pulmonary hypertension. Pulmonary angiogram demonstrated a large aneurysm of main pulmonary artery extending into proximal left pulmonary artery. The pulmonary artery aneurysm associated with patent ductus arteriosus was diagnosed definitively and the patient was underwent resection of pulmonary artery aneurysm, closure of PDA and Dacron prosthetic graft replacement under cardiopulmonary bypass. The postoperative course was uneventful and the patient was discharged without any problem.

Recently ultrasound and scintigraphic study are most useful modality for diagnosis of scrotal diseases. They are able to determine the nature, anatomic extent of the lesion, and possible to differential diagnosis of the scrotal lesion. The ultrasound and scintigraphic findings were analyses in 59 patients of confirmed scrotal disease at Seoul Red Cross Hospital from June 1986 to Aug. 1989. The results were as follows. 1) Most patients were below the 30 years old age (69.4%), and most prevalent age was $11\sim30$ Yrs. in trauma, $31\sim40$ Yrs. in inflammation, and $51\sim60$ Yrs. in mass lesion of scrotum. 2) The diagnostic accuracy of scrotal disease was 94.9% in ultrasound and 72% in scintigraphic study. The ultrasound study showed high accuracy in all kind of scrotat disease, but scintigraphy showed only high detection rate in inflammatory disease. 3) Scrotal ultrasound is first choice of study for the diagnosis of scrotal lesion, and useful determine the cystic or solid lesion and anatomic extent of disease. However it can't be differentiate the acute epididymitis with acute testicular torsion. 4) Scrotal scintigraphy is useful study for the diagnosis of acute painful scrotal disease, and showed specific findings in acute epididymitis and acute torsion for differential diagnosis. 5) In consideration of age, history and clinical findings of patient, appropriate study will be chosen firstly in ultrasound and scintigraphy, and combined all of findings of these studies will be helpful for the accurate diagnosis and adequate treatment of scrotal disease.
