Lipoma arborescens is a rare benign intra-articular lesion that principally affects the knee joint. We present a case of lipoma arborescens involving the glenohumeral joint and associated with prominent large bony erosions. The gadolinium diethylenetriamine pentaacetic acid-enhanced magnetic resonance imaging (MRI) features of this lesion are also(More)
To retrospectively analyze magnetic resonance (MR) findings in patients with popliteal arterial entrapment syndrome. This study was a retrospective MRI and CT scan review of 12 patients with 23 limbs with popliteal artery entrapment syndrome (PAES) treated over a 10-yr period. All 12 patients (23 limbs) were evaluated with MR and CT scan (11(More)
BACKGROUND Non-ionic radiocontrast media (RCM) is rarely associated with hypersensitivity reactions. Premedication of patients who reacted previously to RCM with systemic corticosteroids and/or antihistamines can help reduce recurrent hypersensitivity reactions. However, premedication is still not prescribed in many cases for various reasons. This study(More)
The objective was to determine the importance of the “sagittal shoulder sign” on magnetic resonance (MR) images for the diagnosis of conjoined lumbosacral nerve roots (CLNR) that are compromised by herniated disks. Magnetic resonance images of 11 patients (6 men and 5 women; age range, 25–71 years; average age, 48.7 years) with surgically proven CLNR, which(More)
Bone involvement is an unusual manifestation of secondary syphilis, but little information is available in the English-language literature. We carried out a systematic review of the English-language literature from 1964 to 2013, describing cases of secondary syphilis with bone involvement. We also describe a case of secondary syphilis with multiple(More)
To describe the characteristic US and MR findings of subcutaneous epidermal inclusion cysts. Seventy-nine patients with subcutaneous epidermal inclusion cysts underwent US (n = 70), MR (n = 7), or both (n = 2). On US, the margin, shape, echogenicity, through-transmission, wall, internal debris and vascularity were evaluated. On MR, the shape, wall, signal(More)
OBJECTIVE We wished to report on the MRI findings of non-infectious ischiogluteal bursitis. MATERIALS AND METHODS The MRI findings of 17 confirmed cases of non-infectious ischiogluteal bursitis were analyzed: four out of the 17 cases were confirmed with surgery, and the remaining 13 cases were confirmed with MRI plus the clinical data. RESULTS The(More)
OBJECTIVE We wanted to investigate the relationship between the magnetic resonance (MR) findings and the clinical outcome after treatment with non-surgical transforaminal epidural steroid injections (ESI) for lumbar herniated intervertebral disc (HIVD) patients. MATERIALS AND METHODS Transforaminal ESI were performed in 91 patients (50 males and 41(More)
UNLABELLED We compared the diagnostic sensitivity of (99m)Tc-methylene diphosphonate bone SPECT and MRI in the early detection of femoral head osteonecrosis after renal transplantation. METHODS The patients were 24 renal allograft recipients who underwent both bone SPECT and MRI within 1 mo of each other because of hip pain but normal findings on plain(More)
We present a case of a subcutaneous encapsulated fat necrosis of the upper extremity that mimicked subcutaneous liposarcoma because of heterogeneous signal intensity, its relatively large size, and pronounced enhancement on magnetic resonance imaging (MRI). For this case, we present the radiologic findings including MRI, positron emission(More)
