Juvenile nasopharyngeal angiofibroma (JNA) is a rare, benign, highly vascular, and locally aggressive tumor that predominantly occurs in adolescent males. Usually, the presenting symptom is a painless nasal obstruction or epistaxis; however, other symptoms may develop depending on the size and extent of the tumor mass. Owing to the vascularity of the tumor, incisional biopsy is not attempted. The diagnosis is dependent on multiplanar imaging modalities like Computed Tomography (CT), Magnetic Resonance Imaging (MRI), and Angiography. These imaging modalities help in assessing the tumor mass, pre-operative embolization of the feeder vessel, and treatment planning. Usually, patients with JNA are diagnosed by otorhinolaryngologists, but here, we present a rare case of JNA reporting to the dental hospital due to a tender palatal swelling.
In the present era of increasing road-traffic accidents, facial trauma of variable severity is being frequently encountered involving the orbits and sinuses. Post-traumatic, fronto-ethmoidal and orbital encephaloceles are rare entities requiring early intervention to prevent complications. Cross-sectional imaging by computed tomography and magnetic resonance imaging play a pivotal role in early detection of these entities. Hence in this article, we are describing a rare case of post-traumatic encephalocele with fronto-ethmoidal and orbital components with its clinical presentation which was diagnosed confidently by magnetic resonance imaging affecting the final management.
Colorectal cancer is one of the common causes of cancer-related mortality with rectal cancer representing a significant proportion. Cross-sectional imaging techniques especially computed tomography (CT) and magnetic resonance imaging (MRI) play an important role in preoperative staging of rectal cancer. There has always been a debate about the single best imaging modality for staging of rectal cancer in order to achieve the best surgical outcome. Hence, this article focuses on the comparative role of CT & MRI in staging of rectal cancers.
Background: In the recent era of laparoscopic and robotic surgeries, preoperative imaging has become very crucial in selecting the right operative technique in any pathological condition. Though laparoscopic cholecystectomy is widely accepted and practiced surgical technique yet it has limitations especially dense pericholecystic adhesions where the surgeon requires larger field of view for optimal dissection of gall bladder bed and for optimal control of bleeding. Though ultrasonography has been in wide use for preoperative evaluation of gall bladder stone disease yet very few studies have been conducted to evaluate its role in predicting pericholecystic adhesions responsible for difficult laparoscopic cholecystectomy. Prior knowledge of dense pericholecystic adhesions may help the surgeon in opting for open over laparoscopic cholecystectomy. Methods: Out of 70 patients with gall bladder stone disease that were enrolled in the study, complete data could be obtained in only 55 patients. All patients included in the study underwent ultrasonography of abdomen in fasting state and findings were recorded including pericholecystic adhesions & visualisation of Calot's triangle. The ultrasonographic findings were compared with that of the operative findings. Results: Our study revealed that ultrasonography has more than 70% sensitivity, more than 80% specificity and more than 76% accuracy in predicting pericholecystic adhesions which is the major cause of conversion from laparoscopic to open cholecystectomy. Conclusions: Ultrasonography can serve as an inexpensive imaging tool for predicting difficult laparoscopic cholecystectomy in patients with gall bladder stone disease by demonstrating signs of pericholecystic adhesions and nonvisualisation of normal-appearing Calot's triangle.
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.
