BACKGROUND AND PURPOSE Our purpose was to evaluate the differential findings of tuberculous otomastoiditis (TOM) and nontuberculous chronic otomastoiditis with or without middle ear cholesteatoma on high-resolution CT of the temporal bone. MATERIALS AND METHODS We reviewed 19 cases of TOM, 30 cases of chronic otomastoiditis (COM), and 30 cases of COM with cholesteatoma (CHOM), all of which ha...

Background/Aim: Anatomical variations of paranasal sinuses are common and play an role in disrupting the drainage sinuses, which often causes chronic sinusitis. In this article, anatomical its relationship with mucosal changes were evaluated retrospectively by cone beam computed tomography (CBCT) is also known as dental volumetric tomography. Material Methods: CBCT data 500 patients who applied...

ObjectivesThis study aimed to evaluate the effects of factors related periapical lesions (PALs) on sinus membrane thickening (SMT) in Chinese population using cone-beam computed tomography (CBCT).MethodsIn this retrospective study, CBCT images (n = 512) maxillary sinuses 446 patients were evaluated by two examiners for SMT and PALs, PAL size, distance between floor (MSF), PAL’s edge/root apex. ...

Mucormycosis is an invasive fungal infection caused by fungi of the order Mucorales. Mucorales are ubiquitous in environment association with decaying organic matter. Here we report case a 68-year old female who presented history ptosis left eye decreased vision, facial pain and loss sensation cheek. She had COVID-19 infection. Magnetic resonances imaging brain revealed intense enhancement opti...

Villous atrophy, changes in the surface epithelium, mucosal thickening, and glandular hypertrophy were a feature of all the mucosal biopsies from the small intestine obtained from eight coeliac children. No histological differences were observed between the children previously treated with intermittent gluten-free diets and the untreated children. Serial biopsy studies were carried out on one c...

CT scans of the maxillary antra in a group of 51 patients with nasopharyngeal carcinoma were compared with those of a control group of 50 patients. Inflammatory thickening of the antral mucosa was demonstrated in 39 of 42 patients with grade WHO (World Health Organization) 2 and 3 nasopharyngeal carcinoma. Biopsy of the antral mucosa in eight of these patients established inflammation and exclu...

BACKGROUND Diagnostic imaging of the head is used with increasing frequency, and often includes the paranasal sinuses, where incidental opacifications are found. To determine the clinical relevance of such findings can be challenging, and for the patient such incidental findings can give rise to concern if they are over-reported. Studies of incidental findings in the paranasal sinuses have been...

Unlike other arboreal monocotyledons, the secondary growth of palms has for the past 100 years been described as diffuse. Solely cell enlargement and random parenchyma divisions, without the activity of a meristem, characterize such growth. Some previous works of the early 20th century have, however, mentioned the presence of a secondary meristem in the stems of palms, but this information was ...
