RESUMEN
Aphasia, result from damage of language-dominant area of the brain, usually accompanied hemiparesis due to proximity of language centers and motor control areas. So, global aphasia without hemiparesis is a rare stroke syndrome. We report a case of right handed man with language disturbance after stroke. He showed global aphasia without hemiparesis. We use diffusion tensor image tractography (DTT) for evaluation of global aphasia without hemiparesis. DTT demonstrated that preservation of the corticospinal tract. After speech therapy, he showed improvement of language profile on K-WAB.
RESUMEN
Creutzfeldt-Jakob disease (CJD) is one of the transmissible spongiform encephalopathies, which is mediated by what has been known as "prion". It is a rare and fatal progressive neurodegenerative disease that affects the middle and old aged. There are a number of subtypes of CJD, one of which is the sporadic type characterized by rapidly progressing clinical symptoms, including progressive dementia, myoclonic jerk, and pyramidal or extrapyramidal syndrome. Patients usually end up dying within 1 to 2 years of contacting the disease. We report an autopsy-proven case of sporadic CJD with clinical symptoms that progressed within several days, along with dramatic changes on diffusion weighted magnetic resonance images.

Sclerosing stromal tumor of the ovary is a rare benign neoplasm, with distinctive clinical and pathologic features. It occurs predominantly in females during the second and third decades of life. Histologically, it is composed of cellular and acellular collagenized areas, and edematous stromal areas, and at ultrasonography and computed tomography is seen as a distinctive mixed solid and cystic mass lesion. We report a case of sclerosing stromal tumor of the ovary in a 15-year-old girl with a history of menorrhagia since menarche. Ultrasonography revealed the tumor as a well-defined, lobulated, heterogenous echogenic pelvic mass, while at CT, a huge pelvic mass 9x9x10 cm in size, was seen. This comprised a well-enhanced internal solid portion, a capsule, septa, and a non-enhanced cystic portion.

Human tail is a rare congenital anomaly in which a lesion protrudes from the lumbosacrococcygeal region. We encountered a case of human tail involving an intradural lipoma and tethered cord, occurring in a 1-day -old female who presented with an 8 cm-sized tail shown by MRI to arise from the S3-4 level. The cauda equina and film terminale were entrapped by the lipoma, but there were no bony abnormalities.
