In the March 2009 edition of the Journal of Korean Neurosurgical Society, we published an article entitled "Unilateral Lumbosacral Facet Interlocking without Facet Fracture" (Volume 45, pages 182-184). Fig. 1B on page 183 was supposed to be printed in color, but it was printed in black by mistake. We apologize to the authors and readers of JKNS for any inconvenience.

Diffuse pulmonary meningotheliomatosis (DPM) is an extremely rare condition. We herein report a unique case of DPM in a 54-year-old woman with a previous history of hepatocellular carcinoma. A chest computed tomography showed diffuse bilateral nodular infiltration, suggesting miliary spread of metastatic hepatocellular carcinoma. The patient underwent a video-assisted thoracoscopic surgery for diagnostic purposes. The cut surface of the lung specimen showed multiple dispersed small nodules, consisting of variably sized nests or whorls of bland epithelioid cells often along the walls of alveolar septa or in a perivascular network within the alveolar interstitium. The tumor cells showed immunoreactivity for epithelial membrane antigen, vimentin, and progesterone receptor. DPM should be included in the differential diagnosis of diffuse multiple small nodules or a reticular pattern in the radiologic studies.

We encountered a case of neonatal altoimmune thrombocytopenia(NAIT) due to anti-HLA-B7+B60+B61. Bilateral cephal hematoma and umbilical hematoma were noted at the time of birth. Purpura developed at the third day. Platelet count was 110,000 at birth and decreased to 66,000/micro liter at the day 4. Prothrombin time and partial prothrombin time were within normal limit. The mother's platelet count was 220,000/micro liter and she had no history of abnormal bleeding. Platelet antibody tests empolying mixed passive hemagglutination and immunofluorescence revealed that the mother's serum was reactive against the platelets from the father and the neonate, but was not reactive with her own platelets. Platelets from eight volunteer group 0 donors were tested with the mother's serum; seven were reactive and one was negative. The positive reactions were lost after chloroquine treatment of platelets. Antigen capture ELISA(ACE) and modified antigen capture ELISA employing monoclonal antibodies against platelet glycoproteins In, IIa, IIb, and IIIa were negative. Mother's serum was tested for lymphocytotoxicity against 49 donor ]ymphocytes and the specificity was found to be anti-HLA-B7+B60+B61. At the 9th day, one unit of platelet concentrate from the mother was transfused and the platelet count of the neonate rose up to 340,000/micro liter. The neonate was discharged at the day of sixteenth and the platelet count remained high thereafter.

OBJECTIVE: Although several prior works showed the white matter (WM) integrity changes in amnestic mild cognitive impairment (aMCI) and Alzheimer's disease, it is still unclear the diagnostic accuracy of the WM integrity measurements using diffusion tensor imaging (DTI) in discriminating aMCI from normal controls. The aim of this study is to explore diagnostic validity of whole brain automated probabilistic tractography in discriminating aMCI from normal controls. METHODS: One hundred-two subjects (50 aMCI and 52 normal controls) were included and underwent DTI scans. Whole brain WM tracts were reconstructed with automated probabilistic tractography. Fractional anisotropy (FA) and mean diffusivity (MD) values of the memory related WM tracts were measured and compared between the aMCI and the normal control groups. In addition, the diagnostic validities of these WM tracts were evaluated. RESULTS: Decreased FA and increased MD values of memory related WM tracts were observed in the aMCI group compared with the control group. Among FA and MD value of each tract, the FA value of left cingulum angular bundle showed the highest area under the curve (AUC) of 0.85 with a sensitivity of 88.2%, a specificity of 76.9% in differentiating MCI patients from control subjects. Furthermore, the combination FA values of WM integrity measures of memory related WM tracts showed AUC value of 0.98, a sensitivity of 96%, a specificity of 94.2%. CONCLUSION: Our results with good diagnostic validity of WM integrity measurements suggest DTI might be promising neuroimaging tool for early detection of aMCI and AD patients.

Acute traumatic spondylolisthesis at L5-S1 level is a rare condition, almost exclusively the result of major trauma, frequently associated with transverse process fractures and severe neurologic deficits. Recently, open reduction and internal fixation with posterior stabilization has been the method of treatment most frequently reported. We report a rare case of traumatic L5-S1 pondylolisthesis with a unilateral facet locking with a review of literatures.

We herein describe a 70-year-old woman who presented with respiratory failure due to extensive lung adenocarcinoma. Despite advanced disease, care in the intensive care unit with ventilator support was performed because she was a newly diagnosed patient and was considered to have the potential to recover after cancer treatment. Because prompt control of the cancer was needed to treat the respiratory failure, empirical treatment with an oral epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor was initiated before confirmation of EGFR-mutant adenocarcinoma, and the patient was successfully treated. Later, EGFR-mutant adenocarcinoma was confirmed.

Convex-probe endobronchial ultrasound-guided transbronchial needle aspiration (CP-EBUS-TBNA) has emerged as a new diagnostic modality that allows ultrasound-guided, real-time needle aspiration of mediastinal and hilar lymph nodes. Mediastinoscopy has been the reference standard for neoplastic staging in the mediastinum, but it is invasive and requires general anesthesia. Considering recent prospective studies and clinical guidelines, a needle technique such as EBUS-TBNA and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) should be performed first for the mediastinal nodal staging of non-small lung cancer. Combining EBUS-TBNA and EUS-FNA will replace more invasive methods such as mediastinoscopy. CP-EBUS-TBNA can also be used for the restaging after neoadjuvant therapy, the diagnosis of recurrent lung cancer and central lung parenchymal lesion which abuts trachea or bronchi. In the era of personalized medicine, good-quality and sufficient tissues need to be obtained for the molecular testing and treatment guidance. EBUS-TBNA has the ability to obtain satisfactory material for the detection of EGFR mutation, KRAS mutation, and EML-ALK fusion gene.

Herein we report a rare case of mucinous bronchioloalveolar carcinoma (BAC) associated with a solitary bronchiectatic cyst in a 29-year-old man. The patient presented with hemoptysis and had a history of pulmonary tuberculosis. Chest radiographs and computed tomography revealed a well-circumscribed, thin-walled cavitary lesion in the right upper pulmonary lobe. Gross examination of a lobectomy specimen showed a bronchiectatic cavity and a fungus ball within it. There were also several ill-defined small gray-white nodules around the cyst, nodules that were mucinous BAC. On microscopy, they were composed of columnar tumor cells along the intact alveolar walls in a single layer.
