Accuracy of MRI in the diagnosis of meniscal tears in patients with chronic ACL tears.

Purpose: This study was conducted to evaluate the accuracy of magnetic resonance imaging (MRI) in diagnosing meniscal tears in patients with anterior cruciate ligament (ACL) tears and to determine the frequency of missed meniscal tears on MRI.

Methods: This prospective comparative study was conducted from 2009 to 2012. Patients with ACL injuries who underwent knee arthroscopy and MRI were included in the study.

Diffuse peritoneal lymphomatosis simulating peritoneal carcinomatosis.

Burkitt's lymphoma is a form of Non-Hodgkin's B-cell lymphoma. We report a case of Burkitt's lymphoma mimicking peritoneal carcinomatosis. We will discuss the imaging and clinical findings that differentiate between peritoneal carcinomatosis and Burkitt's lymphoma.

Foetus-in-Fetu.

Foetus-in-fetu is a rare condition in which a calcified mass is in the abdomen of its host, a newborn or an infant. We report a case of a newborn in whom abdominal radiograph and ultrasonography revealed a mass in which the contents favour a foetus-in-fetu. Diagnosis was confirmed by macroscopic examination that showed a soft tissue mass resembling a foetus, attached to the membranous sac.
