Morphology Parameters

The craniovertebral junction area refers to the osseous structures consisting of the occipital bone that surrounds the foramen magnum, the atlas, and the axis vertebrae. There is sparse literature about the morph metric measurement of craniovertebral junction region. We aim to derive a range of various measurements incraniovertebral junction area. This is a hospital based single center retrospective study conducted in our center among 100 consecutive computed tomography scans of craniovertebral junction obtained in adult patients who were admitted to our tertiary hospital for treatment of non-craniovertebraljunction conditions between 2017 and 2018.Various craniovertebral junction morphology parameters were measured and confidence interval at 95% were obtained the range at 2standard deviation. Among 100 patients studied, 51% of them were males while 49% were females. Mean age was 35.1±10.4 years with range from 15 to50 years. Computed tomography measurement of craniovertebral junction revealed meanders height of 30.8±2.5 mms, dento-clivaldistance was 5.9±1.6 mms and mean McRae’s distance of 34.2±2.49 mms. Similarly, anterioratlantodental interval was calculated to be1.83±0.47 mms and posterior atlantodentalinterval was 17.72±0.21 mms while Modified RW distance was 24.43±2.09 mms and Redlund Johnell distance was calculated to be 31.5±4.29mms. Normal morphometric measurements ofcraniovertebral junction can be useful for evaluating abnormalities of the craniovertebraljunction which can potentially improve the diagnostic criteria of most abnormalities.

A case of pulmonary Langerhans cell histiocytosis, proved by both lung high-resolution computed tomography and lung biopsy, is described. Following smoking cessation, lung nodules and cysts gradually disappeared on serial computed tomography scans, with complete clearance of the lesions after 12 months. The role of tobacco smoking is discussed, in detail, against the background of the literature.

Abstract Introduction: Seizures are a common cause of morbidity and mortality in childhood. It is important to establish the cause of seizures to appropriately manage such patients. The etiology of seizures is different in developing countries as compared to the developed world. Computed tomography (CT) scan is easily available, is less sensitive to patient motion, and does not generally require sedation. Also the cost is less as compared to MRI, and this makes it an important screening tool in developing countries like India. Aims: To determine the diagnostic ability of CT to determine the cause of seizures in children. Settings and design: A prospective analytical study. Materials and methods: Computed tomography scans of 84 children presenting with seizures during the period of September 2014 to August 2015 were analyzed. The study was done using 16-slice CT scan. Intravenous contrast was administered as needed. Uncooperative patients were sedated for the scan. Results: Out of 84 scans, 40 scans (47.65%) were found to be abnormal. Maximum number of patients were found to have congenital anomalies (10), followed by hydrocephalus which was found in nine children. Five children had posttraumatic seizures. Four presented with tumors. Four children showed features of hypoxic ischemic encephalopathy. Three each had granuloma and calcification. Two children with seizures had infectious causes, which were clinically diagnosed to be meningitis. Conclusion: Our study indicates that CT is an extremely useful tool for screening the patients of seizures. It is also useful in identifying the treatable causes and monitoring the progression. It is recommended that all children with seizures should be evaluated with CT scan.

Tomography Scan

Eighteen patients were operated on by functional endoscopic sinus surgery who had no ostiomeatal unit obstruction on computed tomography scan and had unremarkable paranasal sinuses. These patients also had no apparent ostiomeatal unit obstruction on diagnostic nasal endoscopy. Data were collected on these patients regarding the impact of very limited functional endoscopic sinus surgery on their principal complaint of recurrent sinusitis with facial pain/headache thought to be of sinogenic origin. Sixteen patients (88.9%) had a reduction in the number of sinus infections requiring antibiotic therapy. This reduction was significant at p < 0.0001. Twelve of 14 patients whose facial pain/headache was believed to be of sinogenic origin had a significant reduction in severity (95% confidence interval, 49.2% to 95.3%). We discuss the role of reversible nasal mucosal disease in the pathophysiology of recurrent rhinosinusifts in this patient population. This was a very small, select group of patients who had specific complaints and had had medical treatment failures. This therapy Is not recommended for every patient, but only a select few with classic complaints of sinus headaches or recurrent sinusitis and negative computed tomography scans.
