Isotretinoin, a medication for acne, has been reported to cause a variety of side effects on the musculoskeletal system. We present a case of sacroiliitis (a relatively uncommon feature) and sensorimotor demyelinating polyneuropathy, which has been reported previously in only a few cases during isotretinoin therapy. Clinical symptoms were improved after the(More)
Anomalous origin of the right vertebral artery from the right common carotid artery occurs rarely. To the best of our knowledge, the medical literature contains no information about gray-scale and Doppler sonography findings in this anomaly, despite the extensive information available from angiographic studies and postmortem examinations. We present the(More)
OBJECTIVES To determine the clinical importance of fibrosis on pelvic magnetic resonance imaging in patients with postprostatectomy incontinence (PPI) due to sphincteric incompetence. METHODS Urethral and periurethral fibrosis was determined by pelvic magnetic resonance imaging in patients who did (n = 22) or did not (n = 14) have urinary incontinence(More)
Central nervous system aspergillosis has increased dramatically in recent years. Most of the cases are immunocompromised patients infected from a primary site, usually the lungs or paranasal sinuses, and the organism may spread to the central nervous system. Different neuroimaging patterns that have been reported vary depending on the immunological status(More)
Carotid blowout syndrome (CBS) is a rare but well-known complication of aggressive radiotherapy management of head and neck cancer. Reports on magnetic resonance imaging (MRI) findings of CBS are limited in the relevant literature, probably because of the angiography priority of this complication. We describe MRI findings in a patient with nasopharyngeal(More)
OBJECTIVE To evaluate and compare the fatty degeneration of multifidus muscles by chemical shift magnetic resonance imaging (MRI) in patients with chronic low back pain and in asymptomatic volunteers. MATERIALS AND METHODS Sixty-five patients with lumbar disc pathology were selected prospectively for this study. The control group consisted of 25(More)
inus pericranii is a rare abnormality that may appear as a midline nasofrontal mass. 1,2 This disorder consists of congenital or acquired anomalous connections between an extracranial blood-filled nodule and the intracranial dural sinuses through dilated diploic and emissary veins of the skull. 3 We report a case of sinus pericranii and present the findings(More)
