Summary Objectives: To report on the frequency and distribution of lesions of the medial coronoid process in dogs of six years of age and older, and to describe the arthroscopic findings in the affected joints. To compare those lesions seen in ‘old’ dogs with those seen in ‘young’ dogs between the ages of five and 18 months. Methods: A retrospective study of dogs six-years-old and older admitted for elbow lameness and subsequent elbow arthroscopy. The dogs were divided into groups according to the lesions of the medial coronoid process diagnosed during arthroscopic examination and computed tomography (CT). The radio-graphic degree of osteoarthritis (OA) and arthroscopically diagnosed lesions on the medial humeral condyle are described. Results: In 51 ‘old’ dogs, five types of lesions could be identified on arthroscopy and CT: chondromalacia-like lesions (2%), fissures (27.5%), non-displaced fragments (12%), displaced fragments (27.5%), and erosions within the medial compartment without fragmentation (31%). A significantly different distribution of lesions was seen in ‘young’ dogs: fissures (23%), non-displaced fragments (45%), displaced fragments (29%), and erosions within the medial compartment without fragmentation (3%). No difference in radio-graphic degree of OA was seen between the two groups. Clinical significance: This study demonstrates the relatively high incidence of medial coronoid disease in dogs older than six years of age, and it highlights one particular problem in ‘old’ dogs: the complete erosion of the medial compartment.

Abstract Background Although gall bladder perforation (GBP) is not common, it is considered a life-threating condition, and the possibility of occurrence in cases of acute cholecystitis must be considered. The aim of this study was to assess the role of multi-slice computed tomography (MSCT) in the assessment of GBP. Results It is a retrospective study including 19 patients that had GBP out of 147, there were 11 females (57.8%) and 8 males (42.1%), aged 42 to 79 year (mean age 60) presented with acute abdomen or acute cholecystitis. All patients were examined with abdominal ultrasonography and contrast-enhanced abdominal MSCT after written informed consent was obtained from the patients. This study was between January and December 2018. Patients with contraindications to contrast-enhanced computed tomography (CT) (pregnancy, acute kidney failure, or allergy to iodinated contrast agents) who underwent US only were excluded. Patients with other diagnoses, such as acute diverticulitis of the right-sided colon or acute appendicitis, were excluded. The radiological findings were evaluated such as GB distention; stones; wall thickening, enhancement, and defect; pericholecystic free fluid or collection; enhancement of liver parenchyma; and air in the wall or lumen. All CT findings are compared with the surgical results. Our results revealed that the most important and diagnostic MSCT finding in GBP is a mural defect. Nineteen patients were proved surgically to have GBP. Conclusion GBP is a rare but very serious condition and should be diagnosed and treated as soon as possible to decrease morbidity and mortality. The most accurate diagnostic tool is the CT, MSCT findings most specific and sensitive for the detection of GBP and its complications.

AbstractAnatomy is the key to accurate imaging interpretation. It is essential for radiologists to thoroughly understand the normal anatomy and spatial relationships of the stomach and duodenum to accurately localize the site of abnormality. In this article, we describe in detail the gross and applied radiological anatomy of the stomach and duodenum, and the current role of various radiological investigations (including barium studies, endoscopic ultrasonography, computed tomography, and magnetic resonance imaging) in the evaluation of the diseases involving the stomach and duodenum.

Abstract Background Combined pulmonary fibrosis and emphysema (CPFE) is a heterogeneous clinico-radiological syndrome without a consensus definition. There are limited data on the relation between the amount of parenchymal fibrosis and prognosis. In this study, we assessed the prognostic implications of the extent of fibrosis assessed by an automated quantitative computed tomography (CT) technique and the radiological and functional change over time in patients with a broad spectrum of fibrotic interstitial lung diseases (ILDs) encountered in a real-world setting. Methods We conducted a single-centre, retrospective study of 228 consecutive patients with CPFE, encountered from 2007 to 2015 at Kameda Medical Center, Chiba, Japan. We investigated the prognostic value of automated CT fibrosis quantification and the subsequent course of CPFE. Results Among 228 patients with CPFE, 89 had fibrosis affecting < 5% of their lungs, 54 had 5 to < 10% fibrosis, and 85 had ≥ 10% fibrosis at the time of diagnosis. Lower volume of fibrosis correlated with lower rates of mortality and acute exacerbation (p < 0.001). In particular, among those with < 5% fibrosis, only 4.5% died and none experienced acute exacerbation during follow-up, whereas 57.6% and 29.4% of those with ≥ 10% fibrosis experienced death and acute exacerbation, respectively. Although, the ≥ 10% fibrosis group had the poorest overall survival as well as the highest incidence of acute exacerbation, the incidence of decline in pulmonary function tests, change per year in total lung volume, and progression of fibrosis on chest CT was highest in the 5 to < 10% fibrosis group. The Cox proportional hazard model for CPFE progression (defined by composite criteria of death, acute exacerbation, and decline in forced vital capacity or diffusing capacity) showed fibrosis proportion was a risk factor independent of age, sex, smoking pack-years, the Charlson Comorbidity Index, lung cancer, connective tissue disease, and idiopathic pulmonary fibrosis. Conclusions Less severe (< 5%) fibrosis at baseline was associated with disease stability and better prognosis compared to more severe fibrosis in CPFE occurring with fibrotic ILDs. Further studies including a validation cohort will be needed. Trial Registration Retrospectively registered.

BACKGROUND: The therapeutic response to endobronchial tuberculosis is usually evaluated by bronchoscopy. Currently, there are no published studies investigating the use of computed tomography for the evaluation of therapeutic response in endobronchial tuberculosis.OBJECTIVE: A retrospective study was performed to evaluate the bronchoscopic and computed tomographic features of endobronchial tuberculosis before and after treatment. The aim of this study was to investigate the usefulness of computed tomography for the assessment of treatment.METHODS: The clinical, pathological and bronchoscopic features of endobronchial tuberculosis were evaluated in 55 patients. The age range of the patients was 21 to 52 years. Computed tomography and bronchoscopy were performed before and after treatment.RESULTS: Diagnosis of tuberculosis was confirmed by culture and histopathological examination. Bronchoscopic examination revealed 89 endobronchial lesions of various types in 55 patients. The exudative type was the most common. Follow-up bronchoscopy revealed that exudative-, ulcerative- and granular-type lesions healed completely. Computed tomography performed after treatment correlated well with the follow-up bronchoscopic findings.CONCLUSION: The results suggest that follow-up computed tomography is useful for the evaluation of therapeutic response and complications associated with endobronchial tuberculosis, and may replace bronchoscopy.
