Agressive osteoblastoma is a very rare primary bone tumor having locally aggressive and destructive natures.But distant metastasis is not well occurred. Aggressive osteoblastoma may be similar to osteoblastomaradiologically, but has different pathological featurs. We experienced one case of aggressive osteoblastomaarising from left ilium and report this case with review of the literatures.

Solid hemangioblastomas of the medulla oblongata are benign vascular neoplasms located in a critical area. We experienced a case of solid hemangioblastoma originated in the medulla oblongata with the syrinx in the cervical spinal cord. Preoperative magnetic resonance imaging provided precise anatomical location and radiologic features of the tumor, which facilitated its total removal. Cardiovascular and pulmonary disorders often complicate this type of surgery, and postoperative dysphagia is a frequent sequelae.

Diffuse tremendous thickening of gastric wall caused by excessive proliferation of the mucosa of unknown causewas first decribed by Menetrier in 1888. The disease is highly uncommon, but the exact preoperative diagnosis iscrucial because of the more excellent prognosis than other malignant lesions including gastric lymphoma andinfiltrative gastric carcinoma. The authors recently experienced a case of Menetrier's disease which had beendiagnosed as gastric lymphoma preoperatively. Radiologic differentiation is not impossible between this extermelyrare disease and other mimicking malignant lesions, that is the reason why we introduce radiographic findings ofthe case by comparison with gastric lymphoma of giant rugal type and infiltrative gastric carcinoma. Typical upperG-I series findings of the case are: 1) Enlarged tortuous proximal gastric rugal folds only along the greatercurvature, 2) Perpendicular lines of barium spicules trapped by apposed folds with clubbed or forked appearance,3) Abrupt transition of transion to normal stomach, 4) No luminal narrowing and retained but sluggish peristalsis.Thus radiologists can diagnose Menetrier's disease scrupulously based on critical application of enlarged foldspattern and extent of the lesion in association with other radiologic features and clinial history of fairly longduration. Brief review of clinical and pathologic features about Menetrier's disease is included.

The management of pineal region tumors remains controversial. Advocates of a conservative approach emphasize the excellent results of radiotherapy, particularly with germinoma, while a number of recent reports have demonstrated the safety of direct surgery. We analyzed 8 cases of pineal region tumors which had been treated at our institution over the past 7 years. Tissue diagnosis was obtained in 3 patients before irradiation and 5 patients underwent irradiation without histological diagnosis. Among 5 irradiated patients initially, four patients had been achieved complete remission by radiotherapy thus they were presumptively germinoma, but other one patient had no response, so she had been underwent surgery. Among 3 biopsy proven cases, 2 were teratoma and other one was embryonal carcinoma. Complete gross microsurgical excision of well encapsulated tumor was possible in two teratoma cases. MRI and other neuroradiological studies have ben found to be useful in indicating the biological nature and histological type of pineal tumor. So, consideration of MRI scans together with tumor markers and response to small dose irradiation will generally allow a specific diagnosis with a high degree of probability. In this way, germinomas may be selected for radiotherapy and the tumor less likely to response may be subject to primary surgery to obtain complete tumor extirpation or tissue diagnosis.

Osteopetrosis is a rare disease by a generalized increase in skeletal density and by abnormalities of bone modeling secondary to defective osteoclastic function with impairment of bone resorption. The various cranial nerve palsies may occur secondary to bony encroachment on the cranial foramina. The authors report a case of osteopetrosis with trigeminal neuralgia. This 30-year-old woman presented with the recurring attacks of severe lancinating paroxysmal pain on her right face(mandibular division>maxillary division>ophthalmic division) for 10 years and anosmia, both blindness for 20 years. Her foramen ovale and optic canal narrowings were caused by osteopetrosis. The neuralgia was refractory to medical treatment. Percutaneous radio-frequency rhizotomy for trigeminal neuralgia was performed and pain relief have been obtained. She was satisfied with the procedure, even if with facial numbness. In the case of trigeminal neuralgia in young patient without abnormal mass lesion on brain radiologic imaging studies, it is important to investigate the bony abnormalities of skull base. The authors believe that radiofrequency rhizotomy is the first choice of treatment for trigeminal neuralgia caused by the bony abnormalities of skull base such as osteopetrosis.

The diversity of the genus Megacollybia in Korea was examined based on morphological observation and analysis of molecular data. Currently, the genus is consisted of nine species with a global distribution. However, only M. platyphylla has been reported in the floral survey of Korea. During our re-evaluation of the taxonomic diversity of Megacollybia in Korea, six Megacollybia specimens collected in 2012 were identified based on internal transcribed spacer (ITS) sequences and morphology. Here, we report two Megacollybia species, M. clitocyboidea and M. marginata, as newly recorded species from Korea. The microscopic features of the two species are provided in this study. To our knowledge, this is the first phylogenetic analysis of Korean Megacollybia species.

During the 2014 survey of the mushroom flora of Gwangneung forest in South Korea, we collected two specimens of boletoid mushroom growing on a felled tree of Pinus koraiensis. These specimens were characterized by a light brown to reddish-brown pileus with appressed tomentum, pore surface bluing instantly when bruised, golden-yellow mycelium at the base of stipe, and lignicolous habitat. Both specimens were identified as Buchwaldoboletus lignicola, a rare basidiomycete, based on morphological characteristics and sequences of internal transcribed spacer (ITS; fungal barcode). Here, we describe these specimens and provide the first report of this genus in South Korea.

Up to 70% of patients with systemic lupus erythematosus (SLE) are afflicted with neurologic manifestations. However, there are only a few reports documenting acute leukoencephalopathy in SLE. We describe a 20-year-old woman who was recently diagnosed as SLE, suffering from headache, fever and arthritis. She developed an acute onset of consciousness disturbance with seizure followed by prolonged coma, which recovered completely after 1 month of steroid therapy. Her brain MRI showed diffuse high signal intensity in the periventricular and subcortical white matter on T2-weighted and FLAIR images, whereas cerebral cortex, basal ganglia, and thalamus were spared. Acute leukoencephalopathy may be recognized as a subtype of lupus involving the central nervous system.
