Abstract Context.—Death from corpora aliena in the larynx is a well-known entity in forensic pathology. The correct diagnosis of this cause of death is difficult without an autopsy, and misdiagnoses by external examination alone are common. Objective.—To determine the postmortem usefulness of modern imaging techniques in the diagnosis of foreign bodies in the larynx, multislice computed tomography, magnetic resonance imaging, and postmortem full-body computed tomography–angiography were performed. Design.—Three decedents with a suspected foreign body in the larynx underwent the 3 different imaging techniques before medicolegal autopsy. Results.—Multislice computed tomography has a high diagnostic value in the noninvasive localization of a foreign body and abnormalities in the larynx. The differentiation between neoplasm or soft foreign bodies (eg, food) is possible, but difficult, by unenhanced multislice computed tomography. By magnetic resonance imaging, the discrimination of the soft tissue structures and soft foreign bodies is much easier. In addition to the postmortem multislice computed tomography, the combination with postmortem angiography will increase the diagnostic value. Conclusions.—Postmortem, cross-sectional imaging methods are highly valuable procedures for the noninvasive detection of corpora aliena in the larynx.

ABSTRACT A 5 mo old male intact English bulldog was evaluated at a veterinary referral hospital for acute respiratory distress and chronic difficulty breathing. Thoracic radiographs revealed multifocal pulmonary hyperinflation and hyperlucency suspected in the left caudal and accessory lung lobes. A thoracic computed tomography scan identified severe diffuse enlargement of the caudal subsegment of the left cranial lung lobe and the dorsal process of the accessory lung lobe, with parenchymal hypoattenuation, rounded margins, and thin pulmonary vessels. Based on clinical signs and imaging findings, he was diagnosed with suspect congenital lobar emphysema in multiple lung lobes. A median sternotomy was performed, which revealed a hyperinflated, emphysematous left cranial lung lobe (caudal subsegment) and accessory lung lobe for which two lung lobectomies were performed. The remaining lung lobes were small and atelectatic. Histopathology revealed bronchial cartilage hypoplasia and aplasia and findings consistent with congenital lobar emphysema. The puppy recovered well from surgical treatment of congenital lobar emphysema, requiring multiple lung lobectomies, with subsequent computed tomography–evidenced re-expansion of the remaining lung lobes 3 mo after surgery. The patient is still alive 1 yr after surgery with a normal activity level and no evidence of respiratory compromise.

Objective. The aim of present study was to evaluate the diagnostic value of multislice computed tomography coronary angiography in patients with left bundle branch block. Materials and methods. Twenty-four patients who underwent both multislice computed tomography coronary angiography and invasive coronary angiography were enrolled in the study. Findings of these imaging modalities were compared in order to determine the sensitivity, specificity, positive predictive value, and negative predictive value of multislice computed tomography angiography in identifying hemodinamically significant stenoses (≥50%). All segments ≥2 mm in diameter were visually assessed independently from their degree of calcification and image quality. Results. In total, 328 segments were analyzed. The Spearman correlation coefficient between multislice computed tomography and invasive coronary angiography was 0.76 (P<0.0001). On a per-segment basis, sensitivity, specificity, positive predictive value, and negative predictive value of multislice computed tomography angiography were 75%, 97.7%, 72%, and 98%, respectively; on a per-vessel basis, these values were 77.8%, 92.3%, 70%, and 94.7%, respectively; on a per-patient basis – 81.8%, 84.6%, 81.8%, and 84.6%, respectively.Conclusions. Multislice computed tomography coronary angiography provides a high diagnostic accuracy in detecting significant coronary artery stenoses in patients with left bundle branch block.
