Renal transplant complications, role of resistive index on colour doppler ultrasound

We evaluated 50 patients who had renal transplants and were sent for Doppler Ultrasound for complications, after the transplant procedure. Ages of the patients ranged from 20 to 65 years, 39 were male and 11 were female. In inclusions only first month post op patients were included and only those patients were considered who had some sort of complications on ultrasound at some stage of the follow up.Following complications were noticed: Diminished corticomedullary demarcations, increased echogenicity with raised R I [20 pt]. Perinephric collections other than haematoma [13 pt]. Perinephric haematoma [06 pt]. Obstructed transplanted kidney [05 pt]. Diminished arterial vascularity of the kidney [04 pt] Renal vein thrombosis [02 pt]. RI was found to be raised in increased echogenicity, obstructed hydronephrotic kidney, diminished arterial supply and was disturbed in RVT

Doppler evaluation of breast solid masses differentiation of benign and malignant masses role of resistive index

To know the usefulness of color and spectral doppler in evaluation of solid breast masses using vascularity and resistive index. We performed duplex doppler sonography on 100 patients presenting with breast mass. Resistive index and vascularity of the vessels were detected and analyzed and correlated with histopathological results. 70% of the benign lesions were found having ri below 0.8 and 45 out of 50 patients had low vascularity.43 malignant lesions had high vascularity and 80% had ri above 0.8. High flow visualization on power doppler and indicates a higher possibility of malignancy lesions with ri greater than 0.8 gives high probability of malignancy

CT scan in evaluation of cardiac masses

To evaluate the usefulness of CT scan in Cardiac tumor A descriptive study with convenient sampling. We studied seven cases referred to us for work up of cardiac masses, the contrast enhanced CT scan was able to identify and give the extent in five of these patients. Two patients were negative on CT scan but were confirmed to have a mass in the cardiac chamber by echocardiography. While CT was able to identify the thrombotic mass extending into the heart in two of the patients which remained inconclusive on echocardiography. CT is better modality for the extent of the lesion and echocardiography is better as an initial modality to screen the cardiac chambers

it aleays DVT? evaluation of leg swelling with color doppler sonography

The aim of this study was to assess the value of duplex ultrasound examination in establishing diagnosis in swollen lower limbs. This study was conducted at the Department of Diagnostic radiology Mayo hospital Lahore. 50 consecutive patients presenting with leg swelling, submitted for colour Doppler sonography of the lower extremities were examined for deep vein thrombosis [DVT]. 46% of the patients were detected as having DVT, when examined through Doppler Ultrasonography. While 28% of the patients were not having any pathology in the limb.26% of the patients were having pathology other than DVT. The veins of the calf muscles are a common site of acute DVT and a source of pulmonary embolism. They should always be investigated in patients with leg swelling. Complete venous evaluation with duplex imaging can be very helpful in determination of underlying cause of the swelling

Pheochromocytoma: review with a case report

Pheochromocytoma is a less common tumour in children, but is a curable lesion. We had a 12 year old boy who presented with bizzare symptoms and the investigations led to the diagnosis of hypertension due to adrenal pheochromocytoma. Its mode of presentation and specific management is reported and a review of literature is presented

experience with obvious external manifestations of neurofibromatosis and review of its etiology and other manifestations

Some cases with various external manifestations of neurofibromatosis have been presented. Attempts were made to reduce some lesions with various surgical procedures to improve disability and appearance. It is much easier to diagnose this condition provided the awareness of this exists. Involvement of internal organs may require several investigations and may remain occult till the symptoms are produced. Several examples of external manifestations presented in this write-up will help the readers in spot diagnosis
