Right antecubital PICCs are more likely to be placed in the central location in relation to the carina. PICCs inserted through the left antecubital veins need to be pushed further down to aim for a central location. Inter-observer variability in identifying the tip of PICCs is least with the introduction of digital imaging.

RESULTS:The superior sagittal, straight sinus and the internal cerebral veins were visualized in all patients. There was hypoplasia of the right transverse sinus in 13 patients, left transverse sinus in 35 patients, right sigmoid sinus in 6 patients and left sigmoid sinus in 19 patients. Absence of transverse sinus on left side was observed in one patient and absence of sigmoid sinus in 2 patients on left side. Flow gaps were observed in non-dominant transverse sinus, sigmoid sinus as well as transverse sigmoid sinus junctions. The occipital sinus was visualized in 17 patients. CONCLUSIONS: MR angiography done at low field strengths is also a reliable method, for assessing cerebral venous sinuses. Awareness of the normal anatomical variations of venous sinuses and apparent MR angiographic flow gaps prevent misdiagnosis of cerebral venous sinus thrombosis.

Capillary haemangiomas rarely occur in the auditory canal and have mainly been managed with surgical excision or kept on close follow up for development of symptoms. Radiotherapy, as a treatment method, has not been reported previously in the published work. We describe a study of a capillary haemangioma in the auditory canal of a 26-year-old woman who presented with bleeding. She was treated with radiotherapy, after the lesion was found to be unsuitable for surgery and embolization. The patient remains well 5 years after completion of treatment.

Aims:To evaluate the accuracy of measurement of hepatic venous pressure gradient by catheter wedge as compared to balloon wedge (the gold standard).Materials and Methods:Forty-five patients having a clinical diagnosis of intrahepatic portal hypertension were subjected to the two different types of pressure measurements (catheter wedge and balloon wedge) during transjugular liver biopsy under fluoroscopic guidance.Statistical Analysis:Spearman's rank correlation coefficient, Bland–Altman plot for agreement, and single measure intraclass correlation were used for analysis of data.Results:There was a close correlation between the results obtained by both the techniques, with highly significant concordance (P < 0.0001). Hepatic venous pressure gradients as measured by the catheter wedge technique were either equal to or less than those obtained by the balloon wedge technique.Conclusions:The difference in hepatic venous pressure gradients measured by the two techniques is insignificant.

We present a rare case of retroperitoneal cystic schwannoma of the pelvis in a patient with Hansen's disease that mimicked an ovarian cyst. Due to economic constraints and because the lesion was assumed to be of ovarian origin, the patient did not undergo any cross-sectional imaging other than sonography. Sonographically guided fine needle aspiration of the cystic lesion was inconclusive. A cystic schwannoma was diagnosed at laparotomy.

Budd-Chiari syndrome (BCS) and portal hypertension is an uncommon complication of hydatid cyst of the liver. Previous reports describe cyst excision or portosystemic shunt surgery for such patients. Here we present a case of hydatid cyst of the liver with BCS that was treated successfully with hepatic venoplasty and transjugular stent placement.

A 50-year-old woman presented with a palpable tender nodule in the upper quadrant of the breast that was clinically thought to be a fibroadenoma, with mammographic findings of a well-defined lobulated density. Sonographic examination revealed a "filarial dance sign" within the cystic lesion, which is diagnostic of lymphatic breast filariasis. In endemic areas, sonographic examination is recommended to search for this pathognomonic real-time diagnostic feature and, if present, to initiate treatment without delay.
