Stereotactic radiosurgery, including gamma knife radiosurgery (GKS), can in rare cases result in
de novo cavernous malformations (CMs). Here, we present a case of de novo CM induced by GKS
following treatment of a cerebellar arteriovenous malformation (AVM). A 48-year-old woman was
diagnosed with left unilateral Moyamoya disease. Conventional cerebral angiography also revealed an
AVM in the left cerebellum. The patient underwent GKS using a 50% isodose of 15 Gy at the margin
of the left cerebellar AVM. Magnetic resonance imaging (MRI) taken 3 years after GKS revealed
small chronic hemorrhages with perilesional edema in the left cerebellum. Five years later, the lesions
became aggravated, but were asymptomatic. Eight years following GKS, the patient was admitted
complaining of headache and dizziness. Brain MRI revealed a 1.3cm hemosiderin deposit with an
inner hyperintense nodular portion that was enhanced in the left cerebellum. An open craniotomy was
performed and the mass was removed, from which pathological findings were compatible with those
for CM. The patient recovered to the prehemorrhagic state. This case shows that De novo CMs can
rarely develop after radiosurgery. Most CMs have been reported to develop following radiosurgery
for brain tumors. As shown in this patient, CMs can also develop after radiosurgery for cerebellar
AVM in adults.

Recurrent dislocation of the peroneal tendon is infrequent but often the injury is a disabling one, and the result of conservative treatment is unsatisfactory. Dislocation of these tendons may be the result of a congenitally shallow groove in the lateral malleolar or of a complete abscence of the groove and the dislocation may be present at birth or may be caused by trauma. We are reporting one case of bilateral recurrent dislocation of the peroneal tendons with- out any history of trauma in which disturbed superior peroneal retinaculum was reconstructed by transposition of the calcsneofibular ligament to the lateral side of the peroneal tendons. The calcaneal insertion of the calcaneofibular ligament was mobilised with a small bone block and reinserted in its bed after the transposition. After a follow up of 13 months, the result was satisfactory.

Cryptococcus is native to the environment and thrives in any type of environment inhabited by birds. Cryptococcal genito-urinary infection has been reported in immunnocompromised patients and can involve the adrenal gland, kidney, prostate, or penis. To our knowledge, there have been no reports of cases where cryptococcal epididymo-orchitis infects an uncompromised healthy host. Here, we report a case of primary cryptococcal epididymo-orchitis in a healthy male.

The number of post-irradiated surgical specimen appears to have risen in recent years due to the increasing utiliz ation of radiotherapy for cancer patients. Radiation therapy damages cells by its effects on the deoxyribonucleic acid and the spectrum of injury ranges from acute self-limited lesion to irreversible chronic lesion. We reviewed 24 cases of post-irradiated specimen and thought that time interval is the main factor influencing the morphologic change. Within six weeks, the individual cytologic changes such as biz arre nuclei, altered nucleus/cytoplasm ratio, amphophilic and vacuolated cytoplasm are noted. Chronic injury resulting from progressive changes in the fibrovascular tissue of the radiated area occur in six months after the initial course of radiation and the vascular changes of intimal thickening and fibrosis, foamy histiocytes within media, periadventital fibrosis and chronic inflammatory cells infiltration are present. Althouhg above mentioned finding are not pathognomonic, we thought them quite constant nd reproducible characteristics of radiation injury.

Matrix metalloproteinases (MMPs) play an important role in the normal morphogenesis, maintenance, and repair of matrix and also have important functions in pathologic conditions characterized by excessive degradation of extracellular matrix, such as rheumatoid arthritis, osteoarthritis, periodontitis and in tumor invasion and metastasis. In this study, expression of MMP-1 and -2 mRNA in retrodiscal tissue of the temporomandibular joint (TMJ) was examined and compared with magnetic resonance imaging (MRI) and surgical findings. MMP mRNAs in the retrodiscal tissue samples were detected by reverse transcription - polymerase chain reaction. TMJ internal derangement (ID) was categorized as normal disc position, disc displacement with reduction, early stage of disc displacement without reduction (DDsR) and late stage of DDsR. TMJ osteoarthrosis (OA) was classified with normal, mild and advanced OA. The amount of synovial fluid collection was divided into not detected, small, large and extremely large amount on MR T2-weighted imaging. Perforation and adhesion were examined during open surgery of the TMJ. Six out of 37 samples were excluded because of little amount of extracted total mRNA. MMP-2 mRNA was detected whole joints, and so the MMP-2 mRNA seems to be expressed normally in retrodiscal tissue. However, MMP-1 mRNA was expressed in 8 of 31 joints. Frequencies of MMP-1 mRNA expression according to the TMJ IDs, amount of synovial fluid and surgical findings made no significant difference. MMP-1 mRNA was detected more frequently in OA groups (7/16 joints, 43.8%) than in normal bony structure group (1/15,joints, 6.7%). Expression of MMP-1 mRNA in retrodiscal tissue might be related with OA of the TMJ.
