RESUMO
Nasolabial cyst is a non-odontogenic, extraosseous, soft tissue cyst, commonly unilateral, located in the nasolabial fold. Bilateral nasolabial cysts are of rare occurrence. This case report describes the multimodality imaging appearance of bilateral nasolabial cysts with a review of literature.
RESUMO
Angioinvasive rhinocerebral mucormycosis is an acute fulminant infection caused by fungi of the order Mucorales that targets uncontrolled diabetics and other immunosupressed individuals. Early imaging features of angioinvasiveness include the presence of thrombosed vessels, especially in the orbital regions and the "black turbinate" sign representing devitalized paranasal sinus mucosa. Intracranial extension carries a grave prognosis, with death reported in 90% of cases. This case report highlights the early and key imaging features of angioinvasive rhinocerebral mucormycosis and a rare complication of complete internal carotid artery thrombosis.
RESUMO
BACKGROUND: Mediastinal lymphadenopathy (ML) presents a diagnostic challenge. The technique to sample the lymph nodes has evolved from conventional "blind" transbronchial needle aspiration (TBNA) to the present day endobronchial ultrasound (EBUS)-guided procedure that improves the accuracy of sampling. OBJECTIVE: This study was undertaken to evaluate the utility of "rapid on-site evaluation" (ROSE) in EBUS-guided TBNA (EBUS-TBNA) for the diagnosis of ML. PATIENTS AND METHODS: This prospective study included 80 patients who underwent EBUS-TBNA for computed tomography/positron emission tomography (CT/PET) diagnosed ML over a 4-month period at a single tertiary care center. All 80 of these patients underwent histopathological evaluation (HPE) in addition to cytology. Three out of these 80 (3.7%) patients were excluded in view of inadequate material on EBUS-TBNA. After the sampling of nodes was done, the slides were stained with rapid hematoxylin and eosin (H&E) and then on-site evaluation was done. The tissue derived was also processed for HPE in all cases. RESULTS: ROSE revealed granuloma in 27 patients and malignancy in 14 patients, and the remaining patients showed nonspecific inflammation. Concomitant histopathology revealed granuloma in 34 patients and malignancy in 14 patients. Considering HPE as gold standard, the overall sensitivity and specificity of EBUS-TBNA for diagnosis were 85.4% and 89.6%, respectively. For malignancy alone, the sensitivity and specificity were 100% and 98.4%, respectively. CONCLUSION: This novel approach is safe, has good diagnostic yield, and has an excellent potential in assisting safe and accurate diagnostic interventional bronchoscope.
