A 44-year-old man came to the emergency room for two-week progressive dyspnea. His medical history included morbid obesity, active smoking and childhood severe trauma that required splenectomy. The computed tomography (CT) pulmonary angiography performed to rule out a pulmonary embolism revealed several peritoneal nodules in the upper abdomen (Figure 1A). The additional abdominal contrast-enhanced CT revealed multiple other nodules and homogeneous disseminated peritoneal masses (Figure1B-C). Splenosis nodules were suspected given the history of splenic trauma and the lack of cancer history. A Tc-99m-tagged heat-damaged

An apparently healthy 31-year-old man presented with dysphonia. Laryngoscopy revealed a mass at the right side of epiglottis. He underwent a CT examination after intravenous injection of a iodinated contrast agent and this showed the presence of a paralaryngeal mass with rim enhancement. The diagnosis of laryngopyocele was made. Treatment consisted of endoscopic laser surgery, confirming the diagnosis and resolving the symptomatology.

Puumala virus (PUUV) is the most common hantavirus in Europe. It is known to cause nephropathia epidemica, which is considered a mild type of hemorrhagic fever with renal syndrome. However, it does not only involve the kidneys and is rarely accompanied by symptomatic hemorrhage. We review the imaging abnormalities caused by PUUV infection, from head to pelvis, emphasizing the broad spectrum of possible findings and bringing further support to a previously suggested denomination “Hantavirus disease” that would encompass all clinical manifestations. Although non-specific, knowledge of radiological appearances is useful to support clinically suspected PUUV infection, before confirmation by serology.

We report the case of a 45-year-old male referred to our hospital with fever, asthenia, visual disturbances and increasing headaches. Diffusion-weighted imaging of the brain showed high signal intensity in the splenium of corpus callosum with low apparent diffusion coefficient values. Diagnosis of cytotoxic lesion of corpus callosum was made with Puumala Hantavirus infection serologically confirmed and should not be mistaken for ischemia. Patient was discharged 8 days after admission and imaging findings had resolved 3 weeks later.

Painless solid testicular masses on ultrasonography are commonly malignant. However, if the lesion is well demarcated, rounded, and hypoechoic with alternating hyperechoic and hypoechoic layers, and no internal vascular flow, the possibility of an epidermoid cyst should be considered. Epidermoid cysts are uncommon benign testicular lesions and are extremely rare in the intrascrotal extratesticular region. Including these cysts in the differential diagnosis may allow the urologist to perform testis-sparing surgery.Teaching Point: The possibility of an epidermoid cyst should be considered when a scrotal mass shows an 'onion ring' appearance on sonography and no vascularity on Doppler.
