Skull vault lesions are rare and represent 1–2% of all bone masses. They are commonly an incidental finding or may be discovered during staging work-up for other diseases. Different classification systems can be employed in order to categorize such lesions: primary (benign and malignant) or secondary as well as neoplastic and non-neoplastic (inflammatory and proliferative). For many of these lesions the clinical and radiological features are often non-specific making the diagnosis cumbersome. Rather than being defined clinical entities, they frequently form part of a spectrum of disease where ruling out an unfavourable progression is of paramount importance. Combining a basic knowledge of the epidemiology, clinical presentation, imaging findings, and histopathology is essential to differentiate these pathologies. The aim of this chapter is to define the important features of each lesion, to offer an overview of the investigations and treatment, and to provide guidance for the differential diagnosis based on imaging. Therefore, pathological entities with similar radiological appearances are grouped together.

Neurovascular Structures

Extra-axial cavernous sinus hemangiomas are rare and account for less than 1% of parasellar tumors. These lesions have characteristic radiological features but the differential diagnosis from parasellar meningiomas and schwannomas can be difficult. Preoperative diagnosis is important due to the risk of severe intraoperative bleeding and the complex neurovascular structures of the cavernous sinus. We describe two cases of cavernous sinus hemangiomas and review the imaging findings of these lesions.

Patient Stress

Hibernomas are a very rare and benign soft tissue tumour that originate from brown adipose tissue. While they are not histologically malignant, they may be indistinguishable from aggressive tumours such as liposarcomas on imaging. It is, therefore, important to consider it as a differential diagnosis when a suspicious fatty lesion is seen on imaging. This may prevent unnecessary invasive surgery and patient stress. This paper illustrates the clinical presentation, radiological features, and histological diagnosis of a patient with a rare dumbbell-shaped hibernoma in the pelvis.

Work Up

A 60-year-old female patient presented with incidental finding of duodenal mesenteric hemangioma during the work up for a ventral hernia. Our patient presented at the age of 60-years-old with complaints of a ventral hernia. After initial imaging on CT showed an incidental finding of a mesenteric mass, an MRI confirmed the diagnosis, in this otherwise asymptomatic female. The patient underwent an exploratory laparotomy with complete excision of the mesenteric mass. Final pathology shows findings of a mesenteric hemangioma. The finding of a mesenteric mass requires further investigation. While benign and rare, mesenteric hemangiomas should be considered as a possible differential diagnosis in patients with radiographic evidence of a mesenteric mass, especially if the patient has symptoms of gastrointestinal hemorrhage. The literature on mesenteric hemangiomas is reviewed. Hemangioma of the GI tract mesentery is a rare pathology but should be included in the differential diagnosis in patients presenting with an intraabdominal mass.

Characteristic Features

Abstract The aim of this pictorial essay is to review the spectrum of fat-containing liver lesions and their characterisation on magnetic resonance imaging with focus on the radiological features that aid in the differential diagnoses. Fat-containing liver lesions comprise a heterogeneous group of tumours with variable imaging findings. Magnetic resonance imaging clearly displays the micro- and macroscopic fat components of the lesions and other characteristic features that are helpful tools to make the differential diagnosis.

Variable Clinical Presentation

Context.— Rosai-Dorfman disease is a rare histiocytic proliferative disorder of unknown pathogenesis that may be diagnostically difficult in extranodal sites. It is commonly an unsuspected diagnosis when arising in bone and soft tissue, especially when it presents without associated lymphadenopathy. Its variable clinical presentation and nonspecific imaging findings make the diagnosis quite challenging, particularly in small biopsies. The problem is compounded by its less-characteristic histomorphologic features in comparison with nodal disease. Awareness of the potential diagnostic pitfalls in Rosai-Dorfman disease of bone and soft tissue should raise the degree of diagnostic accuracy. Objective.— To review the clinical manifestations, imaging characteristics, and histomorphologic features of Rosai-Dorfman disease of bone and soft tissue along with a brief discussion of its differential diagnosis, pathogenesis, and current management. Data Sources.— Thorough review of the literature with focus on clinical manifestations, imaging findings, key histomorphologic features, pathogenesis, and treatment. Conclusions.— The diagnosis of Rosai-Dorfman disease of bone and soft tissue may be quite challenging because of its variable clinical presentation and nonspecific imaging findings. It may be asymptomatic without systemic manifestations or associated lymphadenopathy. The definitive diagnosis relies on histopathologic identification of the characteristic S-100–positive histiocytes demonstrating emperipolesis. Bone and soft tissue lesions tend to have lower numbers of characteristic histiocytes and less conspicuous emperipolesis and often demonstrate areas of fibrosis or storiform spindle cell areas resembling fibrohistiocytic lesions. Awareness of these unusual features is necessary in order to consider Rosai-Dorfman disease in the differential diagnosis when confronting these rare and often misleading lesions.

Rhabdomyosarcoma is an uncommon soft tissue sarcoma that rarely presents in adults. Clinical presentation is dependent on site and size. We present the case of a woman who presented with acute-onset dyspnoea and whose pathology report confirmed embryonal rhabdomyosarcoma (ERMS) seen as an incidental finding on chest computed tomography. We also describe the clinical, laboratory and radiological work-up conducted to diagnose and manage ERMS in the critical care setting.

BACKGROUND: Haemorrhoidal disease (HD) is a benign condition affecting a considerable part of adult population. HD can be considered a social and economic burden with high impact on patient lifestyle. Several new techniques and devices have been proposed for HD treatment; however, preoperative assessment is essential and the use of classification system is recommended. METHODS: In the last two decades many studies described the preoperative assessment and several attempts of classification for HD. This review focuses on the most relevant studies found in literature where classification systems and clinical evaluation with differential diagnosis have been evaluated. RESULTS: The knowledge of classification systems and differential diagnosis for HD has been shown to play a central role in the clinical assessment and in the best treatment choice. Although there are new challenging techniques and devices for HD treatment, a preoperative assessment is always mandatory. CONCLUSION: Preoperative clinical evaluation is essential for HD patient treatment and outcome. Classification systems are useful for the therapeutic choice and for researches on new medical or surgical treatments. In fact, the international guidelines advise several therapeutic options depending on the severity of the HD.
