Pulmonary tuberculosis is common worldwide, and many of these patients develop endobronchial tuberculosis (EBTB). Bronchostenosis is a known complication of EBTB though most patients with endobronchial stenosis do not develop severe bronchostenosis or occlusion. We present a rare case of a patient with a right upper lobe bronchus occlusion and a history of tuberculosis.
Percutaneous cholangiography is typically performed via a transhepatic approach and is reserved for patients with contraindications to traditional cholangiogram imaging modalities. For those with suspected cholelithiasis or choledocholithiasis who cannot undergo magnetic resonance imaging for diagnosis, percutaneous cholecystostomy with cholangiogram is a viable option. Endoscopic retrograde cholangiopancreatography may also be precluded due to anatomic or obstructive limitations, in which case, percutaneous transhepatic cholangiography (PTC) may be indicated for diagnosis. PTC may be difficult in a patient with minimal biliary tree dilatation, or tortuous cystic duct anatomy. In cases such as these, a steerable microcatheter (SMC) may be utilized to enable or expedite PTC. The technique to traverse and catheterize the cystic duct and opacify the gallbladder, bile ducts, and duodenum utilizing an SMC is described. This report outlines a non-vascular application of the SMC resulting in a successful cholangiogram, with reduced operative time and thus reduced radiation exposure to the patient.
Varicella pneumonia is a potentially fatal complication of the Varicella-zoster virus (VZV), which causes the well-known chickenpox disease of childhood. Identifying this type of pneumonia by characteristic features is important for radiologists and radiology residents. Typical manifestations of active Varicella pneumonia include diffuse pulmonary nodules, which may mimic other diseases. Healed Varicella pneumonia can present as diffuse, calcified pulmonary micronodules. We describe a case of healed Varicella pneumonia in a patient with a history of remote VZV infection.
Metastases to the breast from a nonmammary primary are rare. Primary fallopian tube carcinoma is one of the rarest malignancies of the female genital tract. Therefore, breast metastases from primary fallopian tube carcinoma are considered extremely rare.In this article, we shared the case of serous carcinoma of fallopian tube with metastasis to an intramammary lymph node, presenting as a solitary breast mass. On initial staging 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography for this patient with serous carcinoma of fallopian tube, a solitary FDG avid breast mass was found, along with FDG avid multistation nodes. The breast mass was evaluated with diagnostic mammogram and ultrasound and eventually biopsy of this mass revealed metastatic lymph node from carcinoma of fallopian tube origin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
