Unilateral absence of a pulmonary artery (UAPA) is a rare condition with an estimated prevalence of 1 in 200,000 young adults. Most commonly, UAPA occurs in conjunction with cardiovascular abnormalities such as tetralogy of Fallot or cardiac septal defects, but it can also occur in an isolated manner. Patients with isolated UAPA can remain asymptomatic into late adulthood but usually report symptoms such as dyspnea or chest pain or suffer from hemoptysis or recurrent infections. Diagnosis can be difficult due to the rarity of the condition and its nonspecific presentation. We present a case of a 61-year-old man who presented for lung transplant evaluation and was found to have UAPA. Typical findings on chest radiograph, strategies for diagnosis, and available treatments are discussed.

A 72-year-old woman on chronic voriconazole therapy for recurrent histoplasmosis developed a painful forearm mass. Laboratory and imaging findings were consistent with a diffuse periostitis. Her symptoms resolved after discontinuation of voriconazole. To our knowledge, this is the first case of voriconazole-induced periostitis to be reported in a patient with chronic histoplasmosis.

Non-Hodgkin's lymphoma (NHL) is an important and common AIDS-related neoplasm. AIDS-related NHL can be defined by its anatomic distribution as systemic (nodal and extranodal masses), primary central nervous system, and occasionally body cavity-based lymphomas (BCBL). Radiologic imaging plays an important role in differentiating the varied appearances of AIDS-related NHL, particularly regarding BCBL: patients' images demonstrate only fluid in the pleural, pericardial, and/or peritoneal spaces. Imaging of a case of BCBL is presented, including simultaneous pericardial, pleural, and peritoneal effusions.
