Primer hepatik aktinomikoz: İnflamatuar psödotümör olgusu

Actinomycosis is an uncommon chronic infection in which primary liver involvement accounts for 5% of all actinomycotic infections. Abdominal actinomycosis is a severe and progressive peritoneal infection due to an anaerobic gram-positive bacterium, Actinomyces israelii. The presence of a long-standing intrauterine device (IUD) is a well-known risk factor in young women. Although hepatic lesions are present in 15% of cases of abdominal actinomycotic infection, liver involvement in the majority of these cases is attributable to metastatic spread from other evident intraabdominal sites. Hepatic actinomycosis presents most commonly as a single abscess. However, hepatic actinomycosis can closely mimic a malignant tumor on clinical and radiological examination. Such lesions have been termed inflammatory pseudotumors. Tissue specimens for microscopic examination are necessary for diagnosis. We report a rare case of inflammatory pseudotumor of the liver caused by actinomycotic infection.Aktinomikoz nadir görülen kronik enfeksiyöz bir hastalıktır. En sık görülen hastalık formu servikofasiyal enfeksiyondur. Karaciğer tutulumu tüm aktinomikoz enfeksiyonlarının %5’ini oluşturur (1,2). Abdominal aktinomikoz enfeksiyonu bulunan olguların ise yaklaşık %15’inde karaciğer lezyonlarının eşlik ettiği bildirilmekte ve karaciğer tutulumunun batın içindeki herhangi bir primer enfeksiyon odağına sekonder olarak meydana geldiğine inanılmaktadır (1,3,4). Ancak bazı olgularda enfeksiyonun kaynaklandığı primer odak saptanamaz ve bu olgular primer ya da izole hepatik aktinomikoz olarak sınıflandı rılır (1,4,5). Hepatik aktinomikoz sıklıkla soliter apse formasyonu şeklinde izlenir. Buna karşın diğer kronik inflamatuar olaylarda da görülebildiği gibi klinik ve radyolojik olarak nadiren malign tümörü taklit edebilir, bu gibi lezyonlar inflamatuar psödotümör olarak adlandırı- lır (6,7). Bu çalışmada radyolojik bulguları ile psödotümör görünümü oluşturan ve histopatolojik olarak hepatik aktinomikoz tanısı alan olgunun nadir görülen bir patoloji olması nedeniyle, klinik ve radyolojik bulguları nın literatür bilgileri eşliğinde sunulması amaçlanmıştır

A rare case of granulomatous prostatitis caused by Mycobacterium tuberculosis

WOS: 000243573700012PubMed ID: 17024674We report a rare case of infective granulomatous prostatitis caused by Mycobacterium tuberculosis that may be mistaken for prostatic carcinoma, both on clinical examination and transrectal sonography (TRUS). A large hypoechoic mass was detected in the prostate of a 46-year-old man during TRUS and histopathologic examination after TRUS-guided biopsies reported the diagnosis of tuberculous prostatitis. We herein describe the clinical and TRUS findings of this case. (c) 2006 Wiley Periodicals, Inc

Midgut volvulus: Value of multidetector computed tomography in diagnosis

Midgut voluulus is a rare complication of intestinal malrotation in adults. We present a case of intestinal malrotation with surgically proven midgut volvulus. Multidetector computed tomography with postprocessing of imaging data using three-dimensional reconstruction techniques provided better demonstration of the abdomen than other imaging modalities. To our knowledge, this is the first presentation of midgut voluulus on multidetector computed tomography in adults. The literature on midgut volvulus is also reviewed and imaging findings of this disease are discussed

Bellini duct carcinoma of kidney: A case report

Collecting duct carcinoma (CDC) is an unusual variation of renal cell carcinoma. During evaluation of a 64 year old man presenting intermittent hematuria, it was detected right kidney tumor. Radical nephrectomy was performed after embolization of renal artery. He died with multiple organ métastases at the end of the first month after operation. There is no sufficient data about clinical course and treatment of the CDC. Radical nephrectomy is the treatment option for the localized disease
