“…Nevertheless, according to our experience in the study of CT images of the liver and spleen, the liver with an elongated left lobe is not a rare situation. In some patients, the left lobe of liver extends towards left, over the stomach, and even drapes on the spleen [6,9]. Due to the presence of the air in stomach and colon, the spleen is undetectable or obscured from subxiphoid and left subcostal area at US scan, and so is the elongated left lobe of the liver.…”

Aims: The aim of this study was to evaluate the impact of anatomical variation of the elongated left lobe of the liver on the ultrasound detection of focal liver lesions. Materials and methods: We evaluated, by ultrasonography (US), 296 patients with elongated left lobe of the liver and 30 patients with focal lesions in the normal length left lobe of the liver. Those patients had undergone prior computed tomography (CT) evaluation. Results: Of the 296 patients evaluated, 34 patients had focal lesions (the size range 11-20 mm) in the distal region of the elongated left lobe of the liver, and none of the lesions was visualized at US examination (p<0.001). All the focal lesions in the normal length left lobe of the liver of the 30 patients were visualized by US without significant difference between the dimensions established by CT and US (p=0.136). Conclusion: Focal lesions in the distal region of elongated left lobe of the liver are difficult to be detected by conventional US examination and the main reason is the impact of anatomical localization on the examination protocol.

“…[7][8][9][10], but also can cause missed diagnosis of focal lesions at US examination. Recently we proposed a method to improve the visualization of the distal part of elongated left lobe of the liver through intake of sufficient water for distending the stomach, a method that can improve the detection of the focal lesion [11].…”

Imaging of adrenal and renal hemorrhage

et al. 2015

Hemorrhage of the kidneys and adrenal glands has many etiologies. In the adrenal glands, trauma, anticoagulation, stress, sepsis, surgery, and neoplasms are common causes of hemorrhage. In the kidneys, reasons for hemorrhage include trauma, bleeding diathesis, vascular diseases, infection, infarction, hemorrhagic cyst rupture, the Antopol-Goldman lesion, and neoplasms. Angiomyolipoma and renal cell carcinoma are the neoplasms most commonly associated with hemorrhage in the kidneys and adrenal cortical carcinoma, metastases, and pheochromocytoma are associated with hemorrhage in the adrenal glands. Understanding the computed tomography and magnetic resonance imaging features, and causes of hemorrhage in the kidneys and adrenal glands is critical. It is also important to keep in mind that mimickers of hemorrhage exist, including lymphoma in both the kidneys and adrenal glands, and melanoma metastases in the adrenal glands. Appropriate imaging follow-up of renal and adrenal hemorrhage should occur to exclude an underlying malignancy as the cause. If there is suspicion for malignancy that cannot be definitively diagnosed on imaging, surgery or biopsy may be warranted. Angiography may be indicated when there is a suspected underlying vascular disease. Unnecessary intervention, such as nephrectomy, may be avoided in patients with benign causes or no underlying disease. Appropriate management is dependent on accurate diagnosis of the cause of renal or adrenal hemorrhage and it is incumbent upon the radiologist to determine the etiology.

“…Pelvic imaging with CT has been shown to be more sensitive than plain film in fracture detection [50,51], as well as more reliable in demonstration of bleeding source [52,53]. Pelvic CT can also help predict sites of bleeding prior to interventional angiographic procedures [54,55], but above all a CT examination can differentiate between intra-and retroperitoneal damage with high specificity.…”

Standardized whole-body computed tomography as a screening tool in blunt multitrauma patients

The authors present the potential of using a preset CT protocol covering the whole body of the patient who has suffered blunt trauma to screen for injuries, based on a review of the literature and on 4 years' direct experience. Standardized whole-body CT is the fastest method of examining the whole body, capable of detecting a wide variety of traumatic lesions with a high sensitivity and specificity. Multidetector CT allows a full-body examination to be completed within 5 min, thus minimizing time to diagnosis and the institution of definitive clinical care. Current imaging algorithms that include abdominal ultrasonography and plain radiographic studies need to be reassessed in view of the technical advances in CT diagnosis, but should ultimately depend on the particular imaging capabilities and experience of a given trauma center.
