Spontaneous Closure of a Carotid-cavernous Fistula after Contrast-enhanced Orbit Computed Tomography

Purpose: We report a case of spontaneous closure of a carotid-cavernous fistula (CCF) after contrast-enhanced orbit computed tomography (CT).Case summary: A 80-year-old female was referred to our clinic under suspicion of chronic angle- closure glaucoma because of persistently high intraocular pressure commencing one month prior. Slit-lamp examination revealed a conjunctival injection and corkscrew-like vessel dilatation in the left eye, and a high intraocular pressure. Dilated fundus examination revealed central retinal vein occlusion in that eye. Contrast-enhanced orbit CT revealed a dilated, superior ophthalmic vein in the left orbit, and she was transferred to our department of neurosurgery for digital subtraction angiography (DSA); this is the gold standard imaging modality for the diagnosis of direct and indirect CCFs. DSA was performed two weeks after orbit CT; however, no CCF was visible. Thereafter, the conjunctival injection and the elevated intraocular pressure improved gradually over eight months. We suspect that the CCF closed spontaneously.Conclusions: Our case highlights the fact that a CCF can close spontaneously after contrast-enhanced orbit CT; ophthalmologists may wish to bear this in mind.

Contrast Enhanced Computed Tomography

Neck abscesses are difficult to diagnose and treat. Currently, contrast-enhanced computed tomography (CECT) is the imaging modality of choice. The study aims to determine the predictive value of CECT findings in diagnosing neck abscess, causes of neck abscess and the most common neck space involved in the local population. 84 consecutive patients clinically suspected to have neck abscess who underwent CECT and surgical confirmation of pus were included. Demographic and clinical data were recorded. 75 patients were diagnosed as having neck abscess on CECT; out of those 71 patients were found to have pus. Overall CECT findings were found to have a high sensitivity (98.6%) and positive predictive value (PPV) (94.7%) but lower specificity (67.2%) in diagnosing neck abscess. The CECT diagnostic criterion with the highest PPV is the presence of rim irregularity (96%). The most common deep neck space involved is the submandibular compartment, which correlates with the finding that odontogenic cause was the most common identifiable cause of abscess in the study population. Thus, in a patient clinically suspected of having neck abscess, CECT findings of a hypodense mass with rim irregularity are helpful in confirming the diagnosis and guiding clinical management.

BACKGROUND Pancreatic lesions range from inflammation to malignancy and are associated with high morbidity and mortality. Imaging pancreatic lesion is challenging as pancreas is located retroperitoneally and with close proximity to bowel and major blood vessels. Abdominal pain, vomiting, and nausea are commonly reported symptoms. They are associated with high morbidity. Multi detector computed tomography (MDCT) is the modality of choice for detecting pancreatic pathology. It is highly sensitive in detecting necrosis, pancreatitis, peripancreatic fluid collections, calcification, neoplasm, pancreatic enlargement, atrophy and cystic lesions of pancreas. Computed tomography (CT) scan has made it possible to identify and detect various benign and malignant pancreatic lesions. METHODS A prospective observational study of 180 patients with complaints suggestive of pancreatic disease was done based on clinical, laboratory and ultrasonography in the Department of Radiodiagnosis, Acharya Vinoba Bhave Rural Hospital, Datta Meghe Institute of Medical Sciences, Sawangi (Meghe). Siemens Somatom 16 slice CT scan machine was used. All 180 patients underwent plain and contrast enhanced CT scan. RESULTS Out of 180 study participants 105 (58.33 %) were with acute pancreatitis followed by 43 (23.89 %) with chronic pancreatitis, 21 (11.67 %) with acute exacerbation of chronic pancreatitis, 10 (5.56 %) participants with carcinoma pancreas and 1 (0.56 %) participant with pancreatic injury participated in the study. CONCLUSIONS Contrast enhanced computed tomography (CECT) is an excellent diagnostic modality to stage severity of inflammatory process, staging of neoplastic lesions and traumatic injury. It is most accurate and affordable non-invasive imaging modality for the evaluation of pancreatic lesions. It is a standard investigation to identify and quantify distribution of various pancreatic lesions and also evaluates activeness and progression of disease. Thus, it helps in accurate diagnosis and characterization of lesion and in proper treatment of patients. KEY WORDS Pancreas, Imaging, Computed Tomography

Abstract: The swellings in the neck can be caused by innumerable pathological lesions arising from the various anatomical structures lying therein. Multi-Detector CT (MDCT) has now become the new standard in a radiological imaging modality. The utilization of MDCT has resulted in improved resolution and considerable reductions in scan acquisition and display time. Aim and Objective: This study is an effort to assess the role of MDCT in detection, characterization and diagnosing neck pathologies that correlate cytologically. Material and Methods: A study of 50 cases in a clinically suspected neck mass was studied for 1 year. Contrast-enhanced Ct neck was done and Specific CT criteria were used to characterize the mass so that a probable diagnosis could be made. MDCT diagnoses then compared with cytological results to conclude the efficiency of MDCT analysis of neck mass. Conclusion: Multi-detector computed tomography helps in precise anatomical localization and characterization of neck masses. Hence, it will be a method of choice for initial evaluation, preoperative planning, and biopsy targeting and postoperative follow-up. Key Words: Neck mass; Cervical lymph node; Computed tomography; Carcinoma.
