Marchiafava-Bignami disease (MBD) is characterized by cerebral white matter lesions associated with chronic alcoholism. Premortem diagnosis of MBD is usually based on history and clinical manifestations. We report a case of acute MBD in which diffusion-weighted MRI (DWI) showed high signal intensities along the white matter including the corpus callosum. DWI may be useful in premortem diagnosis of acute MBD.

Autoerotic death is an accident occurring during individual, usually solitary sexual activity in which a device or apparatus used to enhance the sexual stimulation. Although it is a well-known phenomenon described in many forensic medicine reports, cases are rare in Korea because of conservative tradition of the society and embarrassment of the victim 's family members. It may be far more common than realized. We present a case of the autoerotic accident involving a plastic bag asphyxia in a 67-year-old man. The death scene investigation and findings at autopsy will provide police officers and physicians with adequate knowledge about this phenomenon to make an accurate diagnosis.

Since patients with intracranial neoplasms usually represent their neurological symptoms rather early in the course of the disease, sudden unexpected death due to intracranial neoplasms is an uncommon event seen only exceptionally in medicolegal autopsy practice. Although meningiom is one of the most common primary intracranial neoplasms, sudden death due to the tumor is an uncommon event. We report a sudden, unexpected death of a 56-year-old female with an undiagnosed olfactory groove meningioma. It is assumed that peritumoral edema is related to the sudden death among the several mechanisms.

Congenital pneumonia is defined as pneumonia acquired transplacentally or perinatally. It is frequently associated with prolonged rupture of the membranes, chorioamnionitis, prolonged labor, premature labor, fetal distress, prematurity and meconium staining. It is one of the important causes of neonatal death. We report a case of congenital pneumonia of a full-term, female neonate who was born by cesarian section and died at 10th hours of her life. There were no maternal signs and symptoms of infection and amniotic fluid was not stained with meconium at birth. We insist that full physical examination and routine laboratory examinations including simple chest X ray are required even in grossly normal neonate without specific risk factors and that possibility of neonatal pneumonia should always be considered when the cause of death cannot be explained immediately by gross autopsy findings.

Peripheral scalp T-cell lymphoma is a very rare disease. We report a case of a 22-year-old man who presented an indolent large scalp mass in the right frontal scalp region. The patient’s physical examination demonstrated no palpable mass in the chest, abdomen, and extremities. The brain CT revealed a high-density large scalp mass of the subgaleal layer in the right frontal and a small scalp mass of the subgaleal layer in the left frontal. The brain MRI showed multifocal enhancing masses in the bilateral dura, the subgaleal layer of the scalp, and the skull. The patient underwent removal of the tumor found in the right frontal scalp. The histologic diagnosis was peripheral T-cell lymphoma. Bone marrow aspiration showed the involvement of T-cell lymphoma. The patient received chemotherapy with cyclophosphamide, vincristine, doxorubicin, and prednisolone (CHOP protocol) for 3 cycles. The patient was discharged without neurological deficit. The patient showed no evidence of recurrence 15 months after surgery. We report a rare case of peripheral T-cell lymphoma mimicking benign scalp tumors.

A 72-year-old male presented with respiratory discomfort. A simple chest X-ray and abdominal computed tomography showed pleural effusion and multiple lymph node enlargement. The pleural effusion was determined by thoracentesis to be chylothorax. An inguinal lymph node biopsy showed peripheral T-cell lymphoma. Following three cycles of cyclophospamide, hydroxyl doxorubicin, vincristine, prednisolone (CHOP) chemotherapy, a partial response was observed. Chylothorax is an extremely rare complication of T-cell lymphoma. We present a case of peripheral T-cell lymphoma presenting with chylothorax. We suggest that clinicians should consider chylothorax when examining patients with lymphoma who present with atypical pleural effusion.

Sudden manhood death syndrome (SMDS) is a disorder found in southeast Asia, particularly Thailand, Philippines and Japan, which causes sudden cardiac death during sleep. In Korea, SMDS cases have been occasionally encountered in forensic autopsy practice. However, the incidence and pathogenesis has been rarely studied. This study to review chronologically the proposed pathogenesis of SMDS; pathology of cardiac conduction system, sleeping and breathing disorder, K+ and thiamine deficiency, mental stress, testosterone, hyperlipidemia, and narrow circumference of coronary artery. Brugada syndrome and SMDS are phenotypically, genetically and functionally the same disorder and Brugada syndrome has been a subject of intensive study since its early description in 1992. While Brugada syndrome is an inherited cardiac disorder caused by mutations in the SCN5A gene encoding the cardiac sodium channel alpha-subunit. less than 20% of its patients are known to be associated with SCN5A mutations. Moreover, the postmortem molecular screening of SCN5A mutations on formalin fixed paraffin embbeded cardiac tissues from SMDS cases has not been rewarding due to technical problems. The role of structural heart disease and sodium channel dysfunction in the induction of electrical instability in SMDS and Brugada syndrome is still debatable.

Endoscopic thoracoscopic sympathicotomy (ETS) for treatment of hyperhidrosis is usually considered as a simple and safe procedure. The complication of ETS is low and no death following ETS has ever been reported in the literature without anecdotal fatal cases. Recently, we experienced two cases of intraoperative cardiac arrest and death. Two patients are suffered from sudden cardiac arrest after transection of the left sympathetic nerve trunk by the thoracoscopic method. Vigorous cardiopulmonary resuscitations were performed but both patients are not recovered. Autopsy examinations are performed and there are no remarkable pathology.

Treatment by All-trans retinoic acid (ATRA) followed by anthracycline-AraC chemotherapy has improved the outcome of acute promyelocytic leukemia. ATRA is usually well tolerated, but a few major side effects can be observed. Retinoic acid syndrome (RAS) often occurs during the induction chemotherapy of acute promyelocytic leukemia. A pericardial effusion is a common cardiac manifestation but myocarditis has been rarely documented. Here we reports a very rare case of fully recovered myocarditis as a result of RAS related to ATRA administration during induction treatment of acute promyelocytic leukemia which documented by echocardiographic evidence.

Thrombotic thrombocytopenic purpura (TTP) and the related hemolytic uremic syndrome (HUS) are disorders characterized by thrombocytopenia, microangiopathic hemolytic anemia, a variable degree of impairment of renal function and fluctuating neurological symptoms, which are thought to be due to platelet activation and subsequent formation of thrombi in the microcirculation. The fact that there was no clear-cut clinical and laboratory features that differentiate HUS from TTP has lead to view these two syndromes as a clinical continuum. Microvascular thrombosis is the typical lesion and closely related with endothelial injury and platelet activation. Pathologic alterations of the brain parenchyma are mainly manifested by small multiple infarcts. Numerous cases of CNS complications of these syndromes have been evaluated by using CT, but few reports have mentioned the MR findings. We experienced a case of TTP-HUS that had clinical features of cortical blindness and the brain lesion was confirmed by MRI showing cerebral infarct at the occipital area but it was reversible course. So we report this case with a brief review of literature.
