Schwannoma, which is also known as neurilemmoma, is a type of tumor that arises from the peripheral nerve sheaths. Cases of schwannomas located in different regions have been reported. Some schwannomas present as asymptomatic masses, while others cause discomfort, such as pain and numbness. Magnetic resonance imaging (MRI) is a valuable diagnostic tool. A 23-year-old woman presented to our hospital with a mass in the left axilla that was misdiagnosed as mammae erraticae. The patient also considered the condition to be mammae erraticae for approximately 14 months because of a lack of symptoms. MRI was recommended by a surgeon from the galactophore department. A giant schwannoma was found. The mass was surgically excised, while preserving the continuity of the long thoracic nerve. Routine histopathological analysis confirmed the presence of a benign schwannoma. Schwannomas located in the axilla are rare and may be easily misdiagnosed as mammae erraticae or enlarged lymph nodes. Early investigation is necessary to make the diagnosis, and surgical excision is usually curative.

AbstractThe present study is a case report of vulvar lipoma. The vulva is a rare site for the development of lipomas, and the aim of the study is to determine if the current imaging modalities can diagnose lipomas correctly. A 43-year-old patient presented with a painless, slowly progressive, oval, mobile and non-tender right vulvar mass compressing the vagina and totally covering the introitus. Both the ultrasonography and magnetic resonance imaging (MRI) exams suggested the diagnosis of lipoma. Surgical excision was performed, and the histopathological examination of the mass confirmed a lipoma.

Abstract Many advances have been made in the imaging diagnosis and in the histopathological evaluation of HCC. However, the classic imaging and histopathological features of HCC are still inadequate to define patient’s prognosis. We aimed to find the link between new proposed morphovascular patterns of hepatocellular carcinoma (HCC) and magnetic resonance imaging (MRI) features to identify pre-operatory markers of biologically aggressive HCC. Thirty-nine liver nodules in 22 patients were consecutively identified. Histopathological analysis and immunohistochemistry for CD34 and Nestin were performed to identify the four different HCC morphovascular patterns. MRI was performed using gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid. Three out of four morphovascular HCC patterns showed peculiar MRI features: in particular Pattern D (solid aggressive HCCs with CD34+/Nestin+ new-formed arteries) were isointense on T1-WI in 83% of cases and hyperintense on T2-WI in 50%. Five histologically-diagnosed HCC were diagnosed as non-malignant nodules on MRI due to their early vascularization and low aggressiveness (Pattern A). The comparison between histology and MRI confirms that a subclassification of HCC is possible in a pre-operatory setting. MRI seems to reinforce once more the identity of the different morphovascular HCC patterns and the possibility to pre-operatively identify HCCs with features of biological aggressiveness.

Attention To Detail

Ductography or galactography is a technique used in the diagnostic workup of unilateral, single duct, spontaneous, and bloody or clear nipple discharge. Mammographic imaging with magnification may reveal the source of the discharge. The technique is challenging, yet it can be mastered with attention to detail, a well thought-out protocol, and practice. Imaging findings can be non-specific, yet may guide biopsy or surgical excision. Now with the wide use of breast magnetic resonance imaging (MRI), which has been shown to be more sensitive for lesion detection, ductography is used less frequently. This chapter, appearing in the section on interventions and surgical changes, reviews the indications, procedure protocols, and pitfalls, as well as the management and imaging follow-up for ductography or galactography.

Subdural osteomas are extremely rare benign neoplasms. Here, we report the case of a 35-year-old female patient with a right frontal and parietal subdural osteoma. The patient presented with a 2-year history of intermittent headache and fatigue. Computerized tomography (CT) scan showed a high-density lesion attached to the inner surface of the right frontal and parietal skull. Magnetic resonance imaging (MRI) demonstrated T1 hyperintensity and T2 hypointensity of the lesion. Intraoperatively, the hard mass was located in subdural space and attached to the dura mater. Histopathological examination revealed lamellated bony trabeculae lined by osteoblasts and the intertrabecular marrow spaces occupied by adipose tissue. The patient underwent neurosurgical resection and recovered without complication. Surgical excision is recommended to extract the symptomatic lesions with overlying dura mater.

AbstractOrbital schwannomas are rare neoplasms of the orbit. The presenting symptoms are often nonspecific. Classic imaging characteristics seen on magnetic resonance imaging (MRI) and orbital ultrasound can be useful to help aid in the diagnosis of orbital schwannoma. When diagnosed, the goal of treatment is complete surgical excision. The location of the tumor within the orbit dictates which surgical approach would provide the best exposure. When complete excision is achieved, recurrence rates are very low.This article addresses the etiology, patient population, presentation, natural history, and differential diagnosis of orbital schwannomas. Imaging characteristics and histopathologic subtypes are reviewed. Treatment goals, approaches, and specialties involved in the management of these patients is discussed. Finally, a representative case is presented.

Imaging evaluation of uterine masses is important to assess the type of lesion and to target surgery, if surgical excision is necessary. This can be decisive in fertile women with benign masses resembling malignancies, in order to avoid overtreatment. In this study, the magnetic resonance imaging (MRI) appearance of cotyledonoid dissecting leiomyoma of the uterus, a rare benign variant of leiomyoma mimicking malignancy, is presented.

Abstract A 23-year-old pregnant woman presented with sudden diplopia, ataxia, hemiparesis, and headache secondary to a brain stem hemorrhage. Magnetic resonance imaging (MRI) revealed a hematoma associated with a probable cavernous hemangioma of the rostral brain stem. In this report, we discuss the MRI findings leading to the preoperative diagnosis, as well as the surgical techniques involved in the successful resection.

Introduction: Lipomas are benign soft tissue tumors, characterized by the presence of mature adipocytes in histopathology. Their development is slow and their etiologies are still controversial. Frequently subcutaneous, this type of lesion is rarely present in the oral cavity. Observation: A 67-year-old man consulted for a nodule on the inner face of his right cheek which had been developing for several years, with severe discomfort during chewing. The typical clinical aspect of this lesion suggested a lipoma. Magnetic resonance imaging (MRI) was performed before surgical excision in order to establish a differential diagnosis with a well-differentiated liposarcoma. Comments: The various imaging examinations, particularly MRI, combined with the analysis of the fat component and the morphology of the non-fat component (septa) enable us to define several categories of lesions likely to have a benign or malignant character. However, some lesions remain difficult to classify, and it is the histopathological examination along with, if necessary, immunohistochemistry (anti-MDM2 and/or anti-CDK4), which allows to confirm or not the malignancy of a lesion. Histological examination suggested a fibrolipoma. Conclusion: Although benign, the size of a fibrolipoma may can lead to significant functional and aesthetic discomfort for the patient. Surgical excision remains the treatment of choice.
