Discoid lateral meniscus is a well-known entity of the knee whereas Wrisberg ligament-type discoid lateral meniscus is extremely rare. This is a report of a case of bilateral discoid lateral meniscus with peripheral detachment.

Anaplastic lymphoma kinase (ALK) rearrangement, is a kind of driver mutation, accounts for 3%-5% of non-small cell lung cancer (NSCLC). NSCLC patients harboring ALK fusion genes have distinct clinical features and good response to ALK inhibitors. Metastasis from lung cancer to the ovary has rarely been known. We report a case of a 54-year-old woman with bilateral ovarian metastases from ALK rearranged NSCLC. She underwent bilateral salpingo-oophorectomy for ovary masses, which were progressed after cytotoxic chemotherapy although primary lung mass was decreased. Histopathological examination of the ovary tumor showed characteristic adenocarcinoma patterns of the lung and ALK rearrangement.

A castrated male, 6 year-old Shih-Tzu, weighing 4.6 kg with a discharge from the external ear canal and a mal-odor was referred to Verterinary Medical Teaching Hospital, Seoul National University. Radiographic findings were narrowing and focal loss of an air density in the left ear canal and bilateral thickening of the osseous bullae. For more detail examination, computed tomography was used. In computed tomographic findings, bilateral thickening of the bulla wall and increased opacity of the bulla space were observed. Thus this dog was diagnosed as bilateral otitis media. Then surgical correction, total ear canal ablation, was performed successfully and the patient showed a good prognosis thereafter. It is considered that computed tomography might serve as an useful imaging tool for otitis media and that it supplies information not obtained with a conventional radiography.

This paper presents synchronization of bilateral teleoperation system with time delay using genetic algorithm. In general, bilateral teleoperation system has two main goals; stability and transparency. In the presence of time delay between the master and the slave, we guarantee stability, and optimize the parameter of synchronization control law using genetic algorithm.

Bilateral traumatic carotid-cavernous fistulae (TCCFs) is rarely encountered neurovascular disease. For treatment of TCCF, detachable balloons have been widely used. Nowadays, transarterial and/or transvenous coil embolization with placement of covered stents is adopted as another treatment method. We experienced a patient with a bilateral TCCFs who was successfully treated with covered stents. However, cerebral hemorrhage occurred in the bed of previous infarction one day after treatment. Hyperperfusion syndrome was considered as a possible cause of the hemorrhage, so that barbiturate coma therapy was started and progression of hemorrhage was stopped. We emphasize that cerebral hyperperfusion hemorrhage can occur even after successful endovascular treatment of TCCF.

Bilateral coronary artery-pulmonary artery fistula is very uncommon congenital heart disease which occupy small percentage of all coronary arterio-venous fistulas. We experienced a case who was 52 years old female with bilateral coronary artery-pulmonary artery fistula. She complained exertional dyspnea k angina[coronary steal syndrome]. On physical examination, any cardiac murmur was not audible. There was no 0y step-up in right heart catheterization. But selective coronary angiography revealed tortuous aberrant vessels which originated from the canal branch of the right coronary artery k the left anterior descending coronary artery. Both aberrant vessels traversed the right ventricular outflow tract, and conjoined just proximal the pulmonic annulus and drained into the main pulmonary artery. The operation was performed under the extracorporeal circulation with beating heart. The procedures were suture-ligation of the draining orifice in main pulmonary artery & the feeding vessels on the right ventricular outflow tract. Postoperatively her complaints were completely disappeared and the selective coronary angiography revealed no left-to-right shunt.

Angiolymphoid hyperplasia with eosinophilia(Kimura's disease) is a relatively uncommon chronic benign disorder of unknown etiology, predominantly in the head and neck region and associated with lymphadenopathy or salivary gland enlargement. The treatment options are still controversial including medical therapy, surgery, and radiation. Kimura's disease of bilateral postauricular involvement has rarely been reported. We report a male patient with sequentially developed Kimura's disease involving the bilateral postauricular region and was treated by combined surgical excision and steroid therapy.

Bilateral traumatic hemorrhage of the basal ganglia is an extremely rare neuropathologic entity. This report describes a 50year-old man with bilateral basal ganglia hemorrhage with occipital fracture of the skull after head trauma. The mechanism of development of traumatic hemorrhage of the basal ganglia has been not clear. But, it is presumed to be secondary to rupture of the lenticulostriate or anterior choroidal artery by shearing as a result of acceleration/deceleration forces. We briefly summarize our uncommon case and discuss its possible mechanisms.

We present a case of acute spinal epidural hematoma[EDH] following unilateral laminectomy for bilateral decompression[ULBD]. A 45-year-old male presented with severe multi-level spinal stenosis underwent ULBD on the left side at the L2-3 and L3-4 level. Five hours after operation, paraparesis developed along with severe bilateral buttock pain. The CT scan showed an acute spinal EDH at the L2-3 level. The acute spinal EDH was successfully decompressed after emergency decompressive surgery with performing an additional laminectomy on the contralateral side at the L2-3 level. Although ULBD is an effective minimally invasive surgical technique for treating spinal stenosis, the possibility of acute spinal EDH should be kept in mind, as happened in our case.

Although the incidence of unilateral abducens nerve palsy has been reported to be as high as 1% to 2.7% of head trauma cases, bilateral abducens nerve palsy following trauma is extremely rare. In this report, we present the case of a patient who developed a bilateral abducens nerve palsy and hypoglossal nerve palsy 3 days after suffering head trauma. He had a Glasgow Coma Score (GCS) of 15 points. Computed tomography (CT) images demonstrated clivus epidural hematoma and subarachnoid hemorrhage on the basal cistern. Herein, we discuss the possible mechanisms of these nerve palsies and its management.
