High resolution ultrasound with color Doppler is the first-line imaging investigation in the evaluation of acute scrotum. It plays a crucial role in distinguishing urological emergencies necessitating immediate surgical exploration from those that can be managed conservatively. Acute scrotal pathologies can involve the scrotal sac or its contents like testis, epididymis and testicular appendages and could range from benign, self-limiting conditions to emergencies. In this pictorial essay, we briefly review the ultrasonographic technique, scrotal anatomy and characteristic imaging features of various pathologies presented as acute scrotum.

Distinguishing Features

Peripheral nerve sheath tumours (PNST) may be benign or malignant. Benign PNSTs include neurofibroma and schwannoma. Neurogenic tumours share certain characteristic imaging features, suggested by a fusiform-shaped mass with tapered ends, the “split-fat” sign, atrophy of the muscles supplied by the involved nerve, the “fascicular sign,” and the “target sign”; these imaging features are best demonstrated on magnetic resonance imaging. This pictorial essay emphasizes the characteristic signs and distinguishing features of PNSTs on imaging.

Ct And Mri

Fat necrosis of the breast is a challenging diagnosis due to the various appearances on mammography, ultrasound, CT, PET-CT, and MRI. Although mammography is more specific, ultrasound is a very important tool in making the diagnosis of fat necrosis. MRI has a wide spectrum of findings for fat necrosis and the appearance is the result of the amount of the inflammatory reaction, the amount of liquefied fat, and the degree of fibrosis. While CT and PET-CT are not first line imaging examinations for the diagnosis of breast cancer or fat necrosis, they are frequently performed in the surveillance and staging of disease. Knowledge of how fat necrosis presents on these additional imaging techniques is important to prevent misinterpretation of the imaging findings. Gross and microscopic appearances of fat necrosis depend on the age of the lesion; the histologic examination of fat necrosis is usually straightforward. Knowledge of the variable appearances of fat necrosis on a vast array of imaging modalities will enhance a radiologist’s accuracy in the analysis and interpretation of fat necrosis versus other diagnoses.

Anomalous Pulmonary Venous Connections

Variations in pulmonary venous anatomy (in the absence of any anomalous pulmonary venous connections) is not uncommon. Commonly occurring variations include presence of conjoined pulmonary veins (PV), supernumerary PVs and ostial PVs. Variant PV anatomy is often asymptomatic; however, it may assume importance in the pre-procedural planning prior to cardiothoracic surgeries and radiofrequency catheter-directed ablation for PV isolation. It is therefore important that the radiologist is aware of the conventional normal and variant PV anatomy in addition to obvious abnormalities like anomalous PV drainage or PV stenosis/ occlusion. Multidetector CT (MDCT) is often used as the first-line imaging modality for pre-procedural PV mapping as it provides high quality images with short acquisition times and availability of numerous post-processing tools.This pictorial review focusses on the MDCT-based PV imaging describing the reporting nomenclature, the conventional normal as well as non-anomalous variant PV anatomy along with their clinical significance.

Introduction: Incisional hernia or eventration is a frequent complication that affects approximately 10 to 25% of the patients after a laparotomy. These hernias must be repaired because of their significant morbidity. The usual hernial content is the omentum and intestines, the incarceration of other abdominal structures, such as the genitals, is very rare. Observation: We present an unusual case of a large ovarian cystadenoma herniating through a para-umbilical hernia, resection led to full recovery. Discussion: Large para-umbilical hernias are usually irreducible and incarcerated. Omentum, small and large intestine are commonly encountered in these hernias. By reviewing the literature, we found that incarceration of other abdominal structures is quite rare. Thus the transvaginal sonography is the first-line imaging, we may usually need further investigations such as CT, MRI or even surgical exploration, to avoid any unnecessary delay. Conclusion: In conclusion, para-umbilical hernia in adults can be the site of the incarceration of any abdominal organ and urgent exploration is recommended in these cases.

The Many

Glioblastoma is an aggressive primary central nervous system tumour that usually has a poor prognosis. Generally, the typical imaging features are easily recognisable, but the behaviour of glioblastoma multiforme (GBM) can often be unusual. Several variations and heterogeneity in GBM appearance have been known to occur. In this pictorial essay, we present cases of pathologically confirmed GBM that illustrate unusual locations and atypical features on neuroimaging, and review the relevant literature. Even innocuous-looking foci, cystic lesions, meningeal-based pathology, intraventricular and infra-tentorial masses, multifocal/multicentric lesions and spinal cord abnormalities may represent GBM. We aim to highlight the atypical characteristics of glioblastoma, clarify their importance and list the potential mimickers. Although a definitive diagnosis in these rare cases of GBM warrants histopathological confirmation, an overview of the many imaging aspects may help make an early diagnosis.

Background: Merkel cell carcinoma (MCC) is a rare primary cutaneous tumor. The standardized imaging guidelines for diagnosis of MCC have not been established. We report the multimodality imaging features of MCC including CT, MRI and ultrasound with grayscale and color Doppler mode as well as the elastography and even a histopathologic confirmation. Case Report: We report the case of a 76-year old male patient with MCC on the elbow that was treated by excision. On MRI, prominent T2 low signal voiding was noted with branching or chaotic pattern and marked, branching or chaotic vascularity was also seen on color doppler ultrasound. Those findings are corresponded to histology that increases vascularity in stromal tissues of the tumor and in between the tumor cells. Conclusion: A mass in the dermal and subcutaneous layer with marked and branching or chaotic vascularity, may be the unique characteristic that may contribute to early diagnosis of MCC.

Pictorial Essay

Conventional ultrasonographic evaluation (grey scale and Doppler) represents the first line investigation in the acute pathology of the scrotum. Its diagnosis value in acute scrotal pathology is undoubted in regard with hypervascular lesions, but in the evaluation of isoechoic and hypo/avascular lesions i.v. contrast-enhanced harmonic ultrasonography (CEUS) is recommended in establishing a firm and certain diagnosis. Besides these, CEUS has an important role in the evaluation of the remaining viable testicular tissue in cases of testicular trauma, thus guiding a limited excision surgery. This paper aims to discuss the added diagnosis value of CEUS and to illustrate this through various ultrasonographic images suggestive for acute scrotum pathology.
