Inflammatory pseudotumors (IPTs) are rare benign tumor-like lesions in the epididymis. They result from myofibrohistiocytic proliferation of the parenchymal organs of the body, such as the lungs and genitourinary system. A 48-year-old male patient presented with a palpable left scrotal mass and developed painless swelling within two months. Scrotal ultrasound revealed a 3 cm solid mass and sper...

In this article, I would like to define "oops lesions" as soft tissue mass-like lesions that involve surprise or embarrassment for radiologists following the final diagnosis. Examples of "oops lesions" include malignant tumors that appear benign, malignancy-mimicking benign tumors, incorrect identification of epidermal inclusion cysts, and soft tissue pseudotumors. Ultrasonography (US) findings...

As seen on ultrasound, CT and MRI, pancreatic carcinoma typically presents as a focally enlarged mass in the pancreas and/or dilatation of the main pancreatic duct. Some other solid, tumor-like lesions in the pancreatic head may have similar imaging findings and be indistinguishable from pancreatic carcinoma. We retrospectively review the patients who have the solid, tumor-like lesions at pancr...

A 56-year-old man was admitted to Hiroshima University Hospital in 1987 because of radiographic evidence of pulmonary abnormalities, fever, and anorexia. A radiograph of the chest showed bilateral thickening of the pleura in the middle field. A CT scan of the chest disclosed remarkable thickening of the pleura and a tumorous lesion, 2 3 3.5 cm in diameter, with a low density area in the right l...

We read with interest the pictorial review of cardiac neoplasms and pseudotumors by Hoey et al. (1) published in the January 2012 issue of Diagnostic and Interventional Radiology. We want to add our experience with one case of myocardial fibroma diagnosed with magnetic resonance imaging (MRI) that emphasizes the diagnostic importance of the late-enhancement pattern to differentiate myocardial f...

The work assessment is to analyze eyelid tumors diagnosed in the last years in our hospital. We found 471 tumoral and pseudotumoral cases, in which malignant tumors predominated, with 255 cases. The most affected age range was the sixth decade and the majority of tumors were located to lower eyelid. The histopathological study allowed us to establish the lesions type and subtype. The Meibomian ...

Cytomegalovirus (CMV) is responsible for the most common opportunistic infections in patients with acquired immunodeficiency syndrome (AIDS). The colon is a common site for these infections in patients positive for human immunodeficiency virus. CMV rarely presents as an intraluminal inflammatory mass in the colon. Here we report the case of a CMV infection presenting as a mass-like lesion in an...
