Catch-22 for the radiologist.

Here is a scenario not very uncommon for radiologists in day–to-day practice. A pregnant woman, who has symptoms such as pain or bleeding per vaginam, comes to a stand-alone ultrasound clinic for an obstetric ultrasound examination in what is apparently an emergency. She does not have a prescription for ultrasound examination from her obstetrician, either because the obstetrician is not reachable for some reason or there is a technical difficulty in obtaining a prescription at that time. What should a radiologist do in such a case?

Ganglion Cyst of Quadriceps Tendon- A Rare Cause on Anterior Knee Pain.

A rare case of ganglion cyst of quadriceps tendon is described here. A 19-year-old male presented with left anterior knee pain of two weeks duration . The patient gave a history of trauma to the left knee joint while a wrestling match six months ago. Physical examination revealed focal tenderness just above the superior pole of patella without any obvious swelling. Magnetic resonance imaging showed a small cystic lesion within the quadriceps tendon just proximal to the superior pole of patella. Intraoperatively, the excised cystic lesion was found to be filled with gelatinous and viscous fluid. The lesion was confirmed as a ganglion cyst on histopathologic examination.

Intrahepatic Portal Vein Aneurysm: Incidental Ultrasound Diagnosis of an Uncommon Entity.

Portal vein aneurysm is a relatively uncommon entity. It is often an incidental, asymptomatic finding. This pathology is increasingly encountered with frequent use of radiological imaging modalities. We report a case of intrahepatic portal vein aneurysm diagnosed incidentally on ultrasonography in a case of acute gastritis. Recognition of this finding can help to avoid confusion with abdominal masses of other etiologies.
