Clinico-radiological study of pediatric abdominal masses matched by helical computerized tomography [HCT]

This study was conducted on [47] pediatric patients presented with abdominal masses to El-Menia University Hospital from September 1998 to August 1999 [21 males and 26 females] with mean age of 5 years +/- 2 months. All patients were subjected to proper clinical examination, radiological studies including plain X-ray, abdominal ultrasound [US] and helical computed tomography [HCT] and the end result was documented by biopsy. From the study, it was found that renal masses were present in 15 patients; Wilm's tumour in 8, cystic lesions in 4, lymphoma in 2 and subcapsular hematoma in 1 patient. Retro peritoneal masses were present in 12 patents; sarcoma in 5 patients, lymphoma in 3, neuroblastoma, duplication cyst, hematoma and calcified T.B. lymph node each in one patient. Intestinal masses were found in 7 patients; lymphoma in 5 patients, multilocular cyst and intussusception each in one patient. Supra-renal neuroblastoma was present in 5 patients. Hepatic masses were found in 5 patients [abscess, cyst, hepatoblastoma, lymphoma and metastasis]. Splenic masses were present in 3 patients; cystic hematoma in 2 patients and infected hydatid cyst in one patient

Role of computerized tomography [CT] and nasal endoscopy in evaluation of chronic paranasal sinus [PNS] diseases

This prospective study aimed to determine the prevalence of structural anatomic variations and mucosal abnormalities of paranasal sinus [PNS] in patients with chronic sinusitis by using nasal endoscopy and CT scan comparatively. Thirty patients having chronic sinusitis were randomly selected in the period between October 1997 to January 1998. Every patient was subjected to clinical examination, endonasal endoscopic study and CT scan [control and axial images]. Five out of sixty nasal cavities [30 patients] could not be examined endoscopically due to severe nasal polyposis or severe septal deviation. The predominant pathological findings seen by endoscopy were middle meatal discharge [34.5%] and enlarged bulla ethmoidalis [32.7%]. Using CT examination, the mucosal abnormalities of the maxillary sinus were the most prevalent findings [90%], followed by the anterior ethmoid [70%]. Polypoidal mucosa was found in [63.2%] of maxillary sinuses, while minimal mucosal thickening in [60%] of maxillary and posterior ethmoidal sinuses. Agger nasi, Haller's cells and Concha bullosa could not be detected by endoscopy, while visualized clearly by CT scan in [96.7%], [16.7%] and [23.3%] of nasal cavities, respectively
