There are several species of Cryptococcus, but two species—Cryptococcus neoformans and Cryptococcus gattii—cause nearly all cryptococcal infections in humans. Cryptococcosis is one of the most common fungal infections in Brazil and becomes even more important after the onset of the AIDS epidemic. The lung is the main gateway, and also is the most common site, with diverse clinical manifestations ranging from an asymptomatic to severe pneumonia. When symptommatic, most patients present with fever and cough with expectoration or hemoptysis. The most common radiological findings in immunocompetent patients are located images of masses and nodules, while immunosuppression shows interstitial infiltrates and diffuses interstitial opacity. This is a case report of a patient in the third decade of life with breathing-dependent pain at the base of the left hemithorax, who has radiological examination of a mass in the left lung base in contact with the pleura mimicking malignant lung. Lobectomy was performed, as well as the pathological diagnosis of cryptococcosis.展开更多
Krukenberg tumor is a rare ovarian metastatic cancer from the gastrointestinal tract. It accounts for 1%-5% of malignant tumors of the ovaries, usually being bilateral, of solid consistency and may have cystic areas. ...Krukenberg tumor is a rare ovarian metastatic cancer from the gastrointestinal tract. It accounts for 1%-5% of malignant tumors of the ovaries, usually being bilateral, of solid consistency and may have cystic areas. The World Health Organization (WHO) defined it as an ovarian metastasis when the mucus-secreting cells of “signet ring” are present, associated with sarcomatous stromal proliferation. We present a 58-year-old woman with the diagnosis of peripheric cholangiocarcinoma with ovarian metastasis, showing history of pain and increased abdominal volume. Magnetic Resonance Imaging (MRI) showed multiple hepatic solid nodules with predominantly peripheral, centripetal and progressive enhancement, demonstrating hipersignal and restriction on diffusion weighted imaging (DWI). In the anexial region, bulky heterogeneous multiloculated cystic formations with solid components, of probable ovarian origin, were noted. Biopsy of the liver nodules confirmed the diagnosis of cholangiocarcinoma.展开更多
