Miliary cerebrospinal lesions caused by Nocardia beijingensis in an immunocompetent patient.

The genus usually infect immunocompromised patients. Pulmonary nocardiosis is the most common -induced infection while central nervous system (CNS) is the most common extrapulmonary site to develop nocardial disease. Approximately 54 % cases of previously reported nocardial brain abscesses were solitary lesions, while 38 % cases had multiple lesions; but miliary-like ring enhancing lesions have not been reported previously.

[The Skin Findings Associated with Neurotrauma].

Head trauma is a common condition, but often, serious pathological conditions associated with it are hidden. Skin findings in child abuse cases, such as skull base fracture, battle signs, raccoon eye, open head injury, penetrating wounds, traumatic aneurysm of the superficial temporal artery, traumatic carotid cavernous sinus fistula, and fat embolism have been presented in this paper. It is necessary to observe and record skin findings at the time of consultation and to listen to the detailed medical history that resulted in such an injury.

[A Case of Bone Marrow Metastasis of Oligodendroglioma with IDH Mutation and 1p/19q Codeletion].

A 71-year-old woman was transferred to our hospital, complaining of a seizure for the first time. A tumor was detected in the right frontal lobe, and a craniotomy was performed with a partial tumor resection. The pathological diagnosis was oligodendroglioma with IDH mutation and 1p/19q codeletion, and irradiation therapy was performed.
