Lymphorrhea is a rare but potentially severe complication that occurs after various surgical procedures. Untreated lymphorrhea may lead to wound dehiscence, infection, and prolonged hospital stay. Currently, there is no standard effective treatment. Early management usually includes leg elevation, drainage, and pressure dressing. However, these methods are associated with prolonged recovery and high recurrence rates. We report a case of lymphorrhea from a calf wound after endoscopic great saphenous vein (GSV) harvesting for coronary artery bypass grafting (CABG). The patient presented with intractable oozing from the postoperative wound on the right calf. Lymphorrhea perGsisted for 6 weeks despite negative-pressure wound therapy with a long-acting somatostatin. We performed unilateral pedal lymphangiography that confirmed wound lymphorrhea, followed by glue embolization. No recurrence was observed after 8 months of follow-up. This case report demonstrates the successful use of lymphangiography with glue embolization in the control of lymphorrhea after GSV harvesting for CABG.

OBJECTIVE: The purpose of this study was to clarify the pathogenesis of plunging ranulas in regard of the pathway of lesion propagation using CT scans. MATERIALS AND METHODS: We retrospectively reviewed CT scans of 41 patients with plunging ranula. We divided plunging ranulas into two types: type 1 was defined as those directly passing through a defect of the mylohyoid muscle with the presence (type 1A) or absence (type 1B) of the tail sign and type 2 as those through the traditional posterior route along the free edge of the mylohyoid muscle. Images were also analyzed for the extent of the lesion in respect to the spaces involved. As for type 1 lesions, we recorded the location of the defect of the mylohyoid muscle and the position of the sublingual gland in relation to the defect. RESULTS: CT scans demonstrated type 1 lesion in 36 (88%), including type 1A in 14 and type 1B in 22, and type 2 lesion in 5 (12%). Irrespective of the type, the submandibular space was seen to be involved in all cases either alone or in combination with one or more adjacent spaces. Of the 36 patients with type 1 lesions, the anterior one-third was the most common location of the defect of the mylohyoid muscle, seen in 22 patients. The sublingual gland partially herniated in 30 patients. CONCLUSION: Our results suggest that the majority of plunging ranulas take an anterior shortcut through a defect of the mylohyoid muscle.

Arterial dissection is an important cause of stroke. We report two cases of isolated posterior inferior cerebellar artery (PICA) dissection diagnosed by high-resolution vessel-wall MRI (HRVW-MRI). One subject complained of abrupt-onset vertigo and headache, and the other subject had headache, vertigo, and Horner syndrome. Conventional MRA showed only focal dilatation of the PICA, but HRVW-MRI revealed intramural hematoma and double-lumen contour in the PICA, suggesting arterial dissection. We suggest that the use of HRVW-MRI should be considered when diagnosing isolated PICA dissection in a PICA infarct with an unknown cause.

OBJECTIVE: This study was designed to describe the radiological findings of extensively drug-resistant (XDR) pulmonary tuberculosis (TB) and to compare the observed findings with findings of drug-sensitive (DS) and non-XDR multidrug-resistant (MDR) TB in non-AIDS patients. MATERIALS AND METHODS: From September 1994 to December 2007, 53 MDR TB patients (M:F = 32:21; mean age, 38 years) and 15 XDR TB non-AIDS patients (M:F = 8:7; mean age, 36 years) were enrolled in the study. All of the MDR TB patients had received no treatment or less than one month of anti-TB treatment. In addition, all XDR TB patients received either no anti-TB treatment or only first-line anti-TB drugs. In addition, 141 consecutive DS TB patients (M:F = 79:62; mean age, 51 years) were also enrolled in the study for comparison. Chest radiograph, CT and demographic findings were reviewed and were compared among the three patient groups. RESULTS: For patients with XDR TB, the most frequent radiographic abnormalities were nodules (15 of 15 patients, 100%), reticulo-nodular densities (11 of 15, 73%), consolidation (9 of 15, 60%) and cavities (7 of 15, 47%) that were located mainly in the upper and middle lung zones. As seen on radiographs, significant differences were found for the frequency of nodules and ground-glass opacity lesions (all p < 0.001) (more frequent in DS TB patients than in MDR and XDR TB patients). For the use of CT, significant differences (more frequent in MDR and XDR TB patients) were found for the frequency of multiple cavities, nodules and bronchial dilatation (p = 0.001 or p < 0.001). Patients with MDR TB and XDR TB were younger as compared to patients with DS TB (p < 0.001). Imaging findings were not different between patients with MDR TB and XDR TB. CONCLUSION: By observation of multiple cavities, nodules and bronchial dilatation as depicted on CT in young patients with acid-fast bacilli (AFB) positive sputum, the presence of MDR TB or XDR TB rather than DS TB can be suggested. There is no significant difference in imaging findings between patients with XDR TB and MDR TB.

A 63-year-old female complained of transient dysarthria. MRA was conducted to evaluate this symptom, revealing distal internal carotid artery occlusion with collateral vessel development, suggesting Moyamoya disease, which had not been detected in MRA performed 5 years previously. Vascular risk factors and laboratory findings suggested no cardiac or autoimmune diseases. The diameter of stenosis of the middle cerebral artery on high-resolution MRI was 2.11 mm, and genetic evaluation revealed mutation of the gene encoding ring finger protein 213 (RNF213). High-resolution MRI and gene studies are useful for distinguishing between Moyamoya disease and atherosclerosis.

Primary angiitis of the central nervous system (PACNS) is a poorly understood form of vascular inflammatory disease that is restricted to the brain and spinal cord. A 38-year-old woman presented with severe headache and transient aphasia. Her cerebrospinal fluid exhibited aseptic meningitis, and high-resolution vessel-wall MRI (HRVW-MRI) revealed narrowing of multiple intracranial vessels with concentric wall thickening and diffuse enhancement, suggestive of PACNS. High-dose steroid and azathioprine therapy resulted in a significant improvement in vessel wall thickening, and enhancement was observed on the follow-up HRVW-MRI.

Ischemic stroke caused by the cerebral vasculopathy is a rare complication of polyneuropathy, organomegaly, endocrinopathy, monoclonal gammopathy, and skin changes (POEMS) syndrome. We present a case of recurrent ischemic strokes caused by cerebral vasculopathy in a patient with POEMS syndrome. A 34-year-old man presented with gait disturbance and dizziness. Brain magnetic resonance imaging demonstrated acute ischemic stroke in the middle cerebral artery-anterior cerebral artery (MCA-ACA) border zones of bilateral hemispheres. Repeated angiographic studies showed progressive worsening of the left distal internal carotid artery, ACA, and MCA stenoses, along with sustained steno-occlusion of right MCA.

Objective:
Intracranial atherosclerotic stroke occurs through various mechanisms, mainly by artery-to-artery embolism (AA) or branch occlusive disease (BOD). This study evaluated the spatial relationship between middle cerebral artery (MCA) plaques and perforating arteries among different MCA territory infarction types using vessel wall magnetic resonance imaging (VW-MRI).
Materials and Methods:
We retrospectively enrolled patients with acute MCA infarction who underwent VW-MRI. Thirty-four patients were divided into three groups according to infarction pattern: 1) BOD, 2) both BOD and AA (BOD-AA), and 3) AA.To determine the factors related to BOD, the BOD and BOD-AA groups were combined into one group (with striatocapsular infarction [BOD+]) and compared with the AA group. To determine the factors related to AA, the BOD-AA and AA groups were combined into another group (with cortical infarction [AA+]) and compared with the BOD group. Plaque morphology and the spatial relationship between the perforating artery orifice and plaque were evaluated both quantitatively and qualitatively.
Results:
The plaque margin in the BOD+ group was closer to the perforating artery orifice than that in the AA group (p = 0.011), with less enhancing plaque (p = 0.030). In the BOD group, plaques were mainly located on the dorsal (41.2%) and superior (41.2%) sides where the perforating arteries mainly arose. No patient in the AA group had overlapping plaques with perforating arteries at the cross-section where the perforator arose. Perforating arteries associated with culprit plaques were most frequently located in the middle two-thirds of the M1 segment (41.4%). The AA+ group had more stenosis (%) than the BOD group (39.73 ± 24.52 vs. 14.42 ± 20.96; p,/i> = 0.003).
Conclusion
The spatial relationship between the perforating artery orifice and plaque varied among different types of MCA territory infarctions. In patients with BOD, the plaque margin was closer and blocked the perforating artery orifice, and stenosis degree and enhancement were less than those in patients with AA.
