In this pictorial essay, we review the sonographic and other imaging findings of paratesticular masses in correlation with the pathologic findings. The examples include benign and malignant tumors and also non-neoplastic mass lesions of the paratesticular structures. Diagnostic sonographic findings of these mass lesions as well as correlative findings of other imaging methods are presented.
Spinal tuberculosis characteristically involves the paradiscal area of vertebral bodies with a narrowing of the disc space. In this study, we reported four atypical forms of Pott's disease, including one hundred and eighty-four patients treated between 1985 and 1998. Two cases presented with noncontiguous multilevel involvement, where one case had transverse process involvement alone and the other had involvement of the neural arch. Atypical tuberculosis of the spine was found in 2.1% of the patients.
We present a rare case of unilateral phlebectasia of the anterior jugular vein in a 56-year-old male patient whose complaint is a neck swelling that appears during talking. Although in this age group the most common cause of such a mass in the anterior aspect of the neck increasing in size during any type of straining or Valsalva manoeuvre is a laryngocele, phlebectasia of the anterior jugular vein should be considered in the differential diagnosis. Doppler ultrasound and computed tomography are the most useful and non-invasive methods to use for the investigation. Treatment should be conservative.
We report a patient with rhinocerebral mucormycosis whose initial central nervous system involvement was isolated pontine infarction due to basilar arteritis caused by the fungus. The patient was diagnosed and followed by MRI and CT and basilar arteritis was demonstrated well on MRI studies. Involvement of the skull base was shown on CT in the later stage of the disease. The unusual initial presentation of the infection is discussed.
The decreases in the AMA, AMD, diameter of the medial segment of the LRV and PV of the lateral segment of the LRV, and the increases in the PV of the medial segment of the LRV and the diameter of the lateral segment of the LRV in varicocele patients in all positions suggest the entrapment or impingement of the left renal vein between the aorta and the superior mesenteric artery. This has been defined as the "nutcracker phenomenon", which is known to affect varicocele formation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
