A 16-year-old female Bengal tiger (Panthera tigris tigris) infected with Paragonimus kellicotti was described. Noticeable clinical symptom was not observed before death. At autopsy, numerous cysts were found on the pleural surface of the lung. The cysts were spherical, approximately 1.0 cm in diameter, bulge the pleura, and dark red-brown in color. Such cysts were also found in the deeper lung parenchyma, and usually contained adult flukes in pairs. Histopathologically, the cyst was lined with stratified squamous epithelium which arose from metaplasia of bronchial epithelium. Partial hyperplasia and necrotic foci accompanied with inflammatory cells were often observed in the squamous epithelium. The outer part of the cyst was consisted of fibrous connective tissue in which leukocytes were infiltrated. Catarrhal pneumonia was manifested in the adjacent lung tissues.

Accuracy of rectal palpation and ultrasonography for differential diagnosis of subestrous dairy trows were investigatedl using the result of pIRsma progesterone assay. The ovaries were examined 2 times of 10 days interval in 520 posearom and postinsemination subestroHs dairy cows, using rectal palpation and B-mode transrectal ultrasonography. The results of rectal palpation, ultrasonographic examination and measurement of plasma progesterone profiles in 520 subestrous dairy cows were silent brat or error of estrus detection 303 (58.3%), persistent corpus luteum 59 (11.3%), follicular cyst 37 (7.1%), luteal cyst 16 (3.1%), inactive ovary 9 (1.7%), granulosa tumor 1 (0.2%), hydmsalphinx 1 (0.2%), endomehris 81 (15.6%), pyometra 12 (2.3%) and mummified fetus 1 (0.2%), respectively. Accuncy of rectal palpation and ultrasonography for diagiosing ovarian disordeir based on plasma progesterone profiles were silent heat or error of estrus detection 80.5% and 96.7%$\boxUl$ persistent corpus luteum 57.6% and 94.9%, follicular cyst 62.5% and 91.9%1 luteal cyst 62.5% and 87.5%, maclive ovary 55.6% and 88.9% and granulosa cell tumor 100% and 100%, respectively. Acnuucy of rectal palpation for diagnosing uterine disorders based on ultrasonography was pyometra 75.0%1 endometritis 51.9% and mummified fetus 100%, respectively. Cbaracteristic ultrasonographic appearances of ovaries in subestrous dairy cows were as follows; Silent heat or error of estrus detection: anechoic follicle or hypoechoic corpus luteum than ovarian stroma was alternately present on Day 0 (first examination) and Day 10. Follicular cyst: uniformly nonechogenic ovarian structure $\geq $ 25 mm in diameter with a wall < 3 mm was present in ipsilateral on Day 0 and Day 10. Luteal cyst: luteal cyst was similar to follicular cysts but thickness of cystic wall was $\geq $ 3 mm. Inactive ovary : structures within ovaries was not present on Day 0 Bnd Day 10. Characteristic uthssonograpsc appearances of uterus in subestrous dairy cows were as follows; Endometritis: characterized by uterine lumen containing fluid in which 'snowy'echogenic particles art suspended. Pyometra: ultrasonographic appearance of pyometra was diffuse echogenic particles distributed in fluid within the distended uterus, and a thickened uterine wall. These results indicated that ultrasonography was practical far diagnosing reproductive disorders. To diagnosing ovarian disorders, ultrasonography should be carried out 2 times of 10 days interval and rndometritis should be differentiated with uterus of luteal phase in normal cycling cows.

To establish the differential diagnosis and treatment method in bovine ovarian cysts, specially ovarian cysts with corpus luteum, serum progesterone (P$_4$) concentration and ultrasonography for measuring the cystic wall thickness and diameter of cyst and corpus luteum were investigated from slaughtered cows with ovarian cysts. Ovarian cysts were classified 8 types by the number of cyst, cystic wall thickness and present of corpus luteum. Ovarian cysts with corpus luteum were 11 (13.6%) of 81 cows and ovarian cysts without corpus luteum were 70 (86.4%) cows. The incidence rates of 8 various types of ovarian cysts were as follows; 2Ba 33.3%, 2Aa 25.9% and 2Bb 14.8%, respectively. The incidence rates of ovarian cysts without corpus luteum were follicular cyst 59.2% and luteal cyst 27.2%. The cystic wall thickness were 2Ab 3.7 mm and 2Bb 3.5 mm, and the serum P4 concentrations were above 2.0 ng/ml in 1Aa, 1Ab, 1Ba, 2Ab and 2Bb, respectively. In ovarian cysts with corpus luteum, the correlation coefficients between corpus luteum area and serum P$_4$ concentration were 0.45. In ovarian cysts without corpus luteum, there was significantly positive correlations between cystic wall thickness and serum P$_4$ concentration ($r^2$= 0.54, p＜0.01). These results indicate that PGF$_2$$\alpha$ analogues can be choice for treatment of ovarian cysts with corpus luteum and above 3 mm the cystic wall thickness because serum P$_4$ concentrations were above 2.0 ng/ml in ovarian cysts with corpus luteum and thickened cystic wall. In conclusion, it is suggest that ultrasonography is useful diagnostic tool for diagnosis and selection of treatment remedy in cystic ovaries of bovine.

Diagnosis on reproductive failures of dairy cows by ultrasonography was performed for 151 dairy cows. To diagnose types of reproductive failures, ultrasonography (SA 600, Medison, 5.0 MHz rectal linear transducer) was carried out in combination with rectal examination. Of 151 dairy cows, pregnant cows were 13 and the cows in normal estrual cycle were 40 cows, thereby the cows with reproductive failures were 98 cows. 1. Of 98 cows with reproductive failures, the cows with ovarian diseases were 34 cows (34.7%) and the cows with uterine diseases were 41 cows (41.8%). 2. The diameter of follicle in proestrus was 1.94 cm and it was longer than that of follicle in diestrus (p<0.05). 3. The mean size of corpus luteum of pregnant cows was bigger than that of corpus luteum in normal diestrus (p<0.05). 4. The length of cystic corpus luteum was 3.26 and the width of that was 1.91 cm. The length of corpus luteum tissue was 1.95 and the width of that was 1.91 cm excluding the size of cavity in corpus luteum. 5. The mean length of follicular cyst was 3.31 and the mean width of that was 2.3 cm. 6. The mean length and width of luteal cyst was 3.45 and 2.25 cm, respectively. The mean length and width of corpus luteum tissue was 1.15 and 0.67 cm, respectively, excluding the size of cyst in the luteal cyst. 7. The width of uterine horn associated with endometritis was significantly reduced as the period after parturition was elapsed (p<0.05). The mean width of uterine horn within 40 days after parturition was 4.55 cm. These results indicated that ultrasonography is of great use for accurate diagnosis both on ovarian diseases and uterine diseases and that it is very effective to diagnose endometritis in dairy cows.

To evaluate the functional status of ovarian cyst in Korean native cows, progesterone ($P_4$) and estrogen ($E_2$) level of cystic follicular fluid, ultrasonography for measuring the cystic diameter and thickness of cystic wall, and histological findings were investigated in cystic ovaries from slaughtered Korean native cows. Ovarian cysts were classified as single follicular cyst 51 cows (59.3%), multiple follicular cysts 19 cows (22.1%), single luteal cyst 13 cows (15.1%) and multiple luteal cysts 3 cows (3.5 %) by anatomical and ultrasonography. Ovarian cysts were classified as follicular cysts (54 cows), luteal cyst (16 cows) and non-functional ovarian cyst (16 cows) by hormone analysis, anatomical finding and ultasonography The luteal cyst was accurately diagnosed by cystic wall thickness, but follicular cysts was misdiagnosed 16 cows of 70 cystic cows The cystic fluid $P_4$ concentration was 3.3 ng/ml in follicular cysts and 30.1 ng/ml luteal cysts. There was significantly positive correlations between cystic wall thickness and serum $P_4$ concentration in follicular ($r^2=0.59$, p<0.001) and luteal cysts ($r^2=0.65$, p<0.001). These results indicated that ovarian cysts had various stages of degeneration and luteal cyst was accurately diagnosed measurement of cystic wall thickness by ultrasonography, but follicular cysts were not diagnosed only cystic diameter and cystic wall thickness.

Objective : Management of recurrent vestibular schwannomas[VS] after microsurgery or radiosurgery is a complicated subject. However, few studies have documented the outcome of recurrent VS. The authorsreviewclinicalexperience of recurrent VS management and analyzed the efficacy of treatment modalities. Methods : Between 1990 and 2002, 293 patients harboring unilateral VS underwent, microsurgery, radiosurgery, microsurgery followed by radiosurgery. Of these, 26 procedures [in 20 patients] were performed to assessed from an increased tumor size by magnetic resonance imaging[MRI]. The mean age of patients with recurred VS was 46.9 years and the mean follow-up period was 68 months. Radiological characteristics were investigated and growth rates of recurred tumors were calculated by measuring changes in tumor diameter on MRI after treatment. Results : MRI characteristics revealed a lobulated contour in 75% and a cyst in 60% of the patients. Only 1 patient showed neither lobulation nor a cyst. The average diameter of the recurrent tumors were 36.9mm. The overall tumor control rate for initial management was 87.4%, 94.7%, and 98.5% for microsurgery, radiosurgery, and microsurgery plus radiosurgery, respectively. However, control rates for recurrent tumors were lower at 85%, 63%, and 80%, respectively. Conclusion : A cystic nature and a lobulated tumor contour are frequent clinical characteristics of recurrent VS. Microsurgery or microsurgery followed by radiosurgery shows little difference in tumor control rate for primary and recurrent VS. However, radiosurgery alone appears to be less beneficial for recurrent VS.

Objectives: Ganglion cysts require a sustainable treatment that suppresses their frequent recurrence. This study aimed to explore the clinical effects of Scolopendra pharmacopuncture (SP) and electroacupuncture on ganglion cysts. Methods: We retrospectively reviewed the patient records and follow-up reports for 20 patients with wrist ganglion cysts who received SP and electroacupuncture from April 2016 to March 2017. The cyst diameter, recurrence, visual analog scale (VAS) scores for pain, the Korean version of the disabilities of arm, shoulder, and hand (K-DASH) score, and the Korean version of the patient-rated wrist evaluation (K-PRWE) score before and after treatment were noted. Results: After treatment, the cyst diameter decreased significantly from 13.61 ± 6.41 mm to 5.15 ± 6.18 mm (p < 0.001), and VAS score for pain decreased from 1.31 ± 1.77 to 0.41 ± 0.33 (p = 0.021). Further, the K-DASH score decreased significantly from 8.97 ± 12.66 to 2.21 ± 7.39 (p = 0.016), and score for the function subscale of K-PRWE decreased from 11.37 ± 4.48 to 9.1 ± 3.67 (p = 0.046). No recurrences were reported from the followed-up patients. Any complication related to SP or electroacupuncture was not observed, except mild rash, itching, and swelling at the injection site in four patients. Conclusion: Combination of SP and electroacupuncture may be effective in treating ganglion cysts; further prospective studies with large population are needed to clarify the effect of SP and electroacupuncture.

Purpose: Glomus tumor is a benign neoplasm of the normal glomus body, occurring as painful subcutaneous nodules, frequently located in the subungual area. There are few cases of facial glomus tumor reported and we report a case of glomus tumor developing on the columella of nose. Methods: A 68-year-old female presented with a mass of the columella grown for 2 years. The nodule was 0.6 cm in diameter, red-colored without any symptoms such as pain, tenderness and cold hypersensitivity. The pathologic result after punch biopsy was hemangiopericytoma. Excision with local anesthesia was executed. Results: The postoperative recovery of the patient was uneventful, Histopathological examination indicated a glomus tumor. Immunostaining revealed positivity for vimentin, actin, and negativity for desmin, CD-34. After 8 months follow up, there is neither complication nor evidence of local recurrence on clinical examination. Conclusion: To accomplish an accurate diagnosis of glomus tumor, the histopathological examination is essential together with immunochemical studies. The differential diagnosis include hemangioma, lipoma, epidermal inclusion cyst, dermoid cyst and arteriovenous malformation in this region. We report a case of glomus tumor on the face with uncommon clinical features.
