ABSTRACT
Ramsay Hunt syndrome (RHS) is a disease caused by varicella-zoster virus (VZV) infection that can be diagnosed through clinical symptoms with or without imaging evaluations. The typical features of RHS on imaging evaluation include signal changes and enhancement in the internal auditory canal (IAC) nerves, and the labyrinthine segment of cranial nerve VII (CN VII) and cranial nerve VIII (CN VIII). In some patients, inner ear structure (cochlear and vestibular apparatus) is involved in RHS. Neurologic complications, such as encephalitis and meningitis, are rare in RHS, but are known to occur. Therefore, magnetic resonance imaging (MRI) is necessary to detect both abnormal signal intensity in the IAC, CN VII, CN VIII, inner and ear structure, and CNS complications. We report an RHS patient with CN VII, VIII, and leptomeningeal enhancement within the cerebellar folia on 10-min delayed, contrast-enhanced (CE), three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) imaging.

ABSTRACT
Primary central nervous system T-cell lymphoma (PCNSTL) is an extremely rare type of brain tumor. There are only few reports on the imaging findings of patients with PCNSTL. Herein, we report the imaging findings of a patient with peripheral T-cell lymphoma-not otherwise specified that presented with numerous small nodular and patchy strongly enhancing lesions on MRI.
ABSTRACT
Extraintestinal manifestation (EIM) of inflammatory bowel disease (IBD) is approximately 36%. Of genitourinary complications as an EIM of Crohn’s disease (CD), nephrolithiasis is the most common urinary complication in patients with CD. CD patients have been shown to have decreased urinary volume, pH, magnesium, and excretion of citrate, all of which are significant risk factors for nephrolithiasis. Genitourinary complications often occur in case of a severe longstanding disease and are associated with, the activity of bowel disease, especially in those who have undergone bowel surgery. As uncontrolled nephrolithiasis could impair renal function as well as adversely affect quality of life, proper monitoring, early detection, and prevention of the occurrence of urologic complications in CD is crucial. Few data are available about urolithiasis in patients with CD. Herein we report a case of a successful removal of a 2.7 cm calcium oxalate stone using percutaneous nephrolithotomy from a patient with long-standing CD with a previous surgery for small intestinal and colonic stricture.
ABSTRACT
BACKGROUND: Kyphoplasty is a minimally invasive procedure that can stabilize osteoporotic and neoplastic vertebral fractures. We retrospectively evaluated the clinical outcomes of kyphoplasty for the treatment of vertebral compression fractures in cancer patients. METHODS: We reviewed the clinical data of 27 cancer patients who were treated with kyphoplasty (55 vertebral bodies) between May 2003 and Feb 2008. The clinical parameters, using a visual analog 10 point scale (VAS) and the mobility scores, as well as consumption of analgesic, were evaluated preoperatively and at 1 week after kyphoplasty. RESULTS: A total 55 cases of thoracic and lumbar kyphoplasties were performed without complications. The mean age of the patients was 66 years. All the patients experienced a significant improvement in their subjective pain and mobility immediately after the procedures. The pain scores (VAS), mobility scores and other functional evaluations using the Oswestry disability score and the SF-36 showed significant differences between the pre- and postoperational conditions. CONCLUSIONS: Kyphoplasty is an effective, minimally invasive procedure that can relieve the pain of patients with vertebral compression fractures and these fractures are the result of metastasis.

Postpneumonectomy syndrome is a rare and delayed complication of pneumonectomy. This syndrome is caused by the shifting and rotation of the heart and mediastinum into the empty hemithorax. It can be corrected by inserting prosthesis in the empty side of the chest. We experienced a case of postpneumonectomy syndrome in 17 year-old girl that followed by right pneumonectomy for multi-drug resistance tuberculosis (MDR-TB) 9 months ago. The corrective surgery of postpneumonectomy syndrome does not seem to be familiar with anesthesiologists. We report this case with references, as we were unable to find any case report about this maneuver.
