We present the case of splenogonadal fusion in a 53-year-old male patient assessed by ultrasound and MRI, confirmed by pathologic examination. In addition to B-mode and colour-coded Doppler ultrasound, shear wave elastography and CEUS were performed and are presented in detail. Splenogonadal fusion is a rare congenital anomaly presumably caused by an abnormal attachment of splenic tissue to the gonad during gestation. Diagnosis is challenging for clinicians and in unclear cases splenogonadal fusion might cause unnecessary orchiectomies with benign pathologic results. Ultrasound is the first-line imaging modality in the diagnosis of testicular pathologies. This case report summarizes all available modern ultrasound imagingtechnologies and highlights the possibilities for the diagnosis of splenogonadal fusion.

Background The latest International Myeloma Working Group (IMWG) guideline recommends low-dose whole-body (WB) computed tomography (CT) as the first-line imaging technique for the initial diagnosis of plasma cell disorders. Purpose To evaluate diagnostic performances of CT and diffusion-weighted imaging (DWI) as the first-line imaging modalities and assess misclassification rates obtained following the guideline. Material and Methods Two independent radiologists analyzed CT (acquired as PET/CT) and DWI (3-T; b-values = 50 and 900 s/mm2) of patients newly diagnosed with plasma cell disorder, categorizing the number of bone lesions. Diagnostic performance of CT and DWI was compared using the McNemar test, and misclassification rates were calculated with a consensus WB-MRI reading as the reference standard. Differences in lesion number categories were assessed using marginal homogeneity and kappa statistics. Results Of 56 patients (36 men; mean age = 63.5 years), 39 had myeloma lesions. DWI showed slightly higher sensitivity for detecting myeloma lesions (97.4%) than CT (84.6%–92.3%; P > 0.05). CT showed significantly higher specificity (88.2%) than DWI (52.9%–58.8%; P<0.05). CT had a higher additional study requirement rate than DWI (7.7%–15.4% vs. 2.6%), but a lower unnecessary treatment rate (11.8% vs. 41.2%–47.1%). Both readers showed significant differences in categorization of the number of lesions on CT compared with the reference standard ( P < 0.001), and one reader showed a significant difference on DWI ( P = 0.006 and 0.098). Conclusion CT interpreted according to the IMWG guideline is a diagnostically effective first-line modality with relatively high sensitivity and specificity. DWI alone may not be an acceptable first-line imaging modality because of low specificity.

Extensor Tendon Injuries

AbstractTendon injuries represent the second most common injury of the hand (after fractures) and are a common scanning indication in radiology. Pulley injuries are very frequent in rock climbers with the A2 pulley the most commonly affected. Tendon and pulley injuries can be reliably evaluated using ultrasound (US) and magnetic resonance imaging (MRI). US can be postulated as a first-line imaging modality, allowing dynamic examination. MRI is essential for cases with ongoing diagnostic doubt post-US and also for preoperative pulley reconstruction assessment.

Clinical Complaint

Iliotibial band lesions constitute a potential source of discomfort and are frequently confounded with other conditions which cause pain on the lateral aspect of the hip, thigh and knee. Ultrasonography is usually regarded as a first-line imaging modality in the assessment of such conditions because of its excellent diagnostic accuracy, low cost and wide availability. The correct identification of the structure involved in the production of symptoms leads to an appropriate management and to a higher probability of resolution of the clinical complaint. The present article is aimed at reviewing the different sonographic presentations of iliotibial band syndromes.

High Index Of Suspicion

There have been case reports where patients admitted with acute cholecystitis, who were managed conservatively, had subsequently developed GC (gangrenous cholecystitis). The current case is unique, since our patient denied any prior episodes of abdominal pain and the only tip off was leukocytosis. A high index of suspicion is essential for the early diagnosis and treatment of GC. GC has a mortality rate of up to 22% and a complication rate of 16–25%. Complications associated with GC include perforation, which has been reported to occur in as many as 10% of cases of acute cholecystitis. The radiological investigations may not be conclusive. Ultrasonography usually serves as the first-line imaging modality for the evaluation of patients with clinically suspected acute cholecystitis. However, CT can play an important role in the evaluation of these patients if sonography is inconclusive. There is a need for an early (if not urgent) surgical intervention in acute cholecystitis (whether laparoscopic or open surgery) in order to decrease the time elapsed from the start of symptoms to admission and treatment.

AbstractEchocardiography is the first-line imaging modality for assessing cardiac function and morphology. The miniaturisation of ultrasound technology has led to the development of hand-held cardiac ultrasound (HCU) devices. The increasing sophistication of available HCU devices enables clinicians to more comprehensively examine patients at the bedside. HCU can augment clinical exam findings by offering a rapid screening assessment of cardiac dysfunction in both the Emergency Department and in cardiology clinics. Possible implications of implementing HCU into clinical practice are discussed in this review paper.

Spleen pathology is rare in comparison with other abdominal organs, but often its lesions occur in complex pathological contexts, with systemic involvement. Although the lesions could be discretely symptomatic, their evolutionary potential might be severe. Conventional B-mode and Doppler ultrasound are the first-line imaging methods in spleen assessment, but frequently they do not allow the characterization of focal splenic abnormalities. Contrast-enhanced ultrasound (CEUS) is fast, safe, easy to perform, non-irradiating and can be used in patients with renal failure. By highlighting splenic macro and micro-vascularization, CEUS significantly increases the detection rate and allows the characterization of vascular (infarction, ischemia, thrombosis) and traumatic lesions, with high diagnostic accuracy. Additionally, ectopic splenic tissue can be identified with high accuracy. The method improves both the detection and characterization of splenic nodules, but some limitations still remain, especially in the differential diagnosis between malignant and some benign lesions. This article aims to portray aspects of CEUS imaging in various splenic pathologies using clinical examples from our experience and to review the CEUS contribution in the diagnosis of splenic lesions.
