Subgaleal Lipoma: Imaging Findings.

J Belg Soc Radiol 2021 Apr 20;105(1):23. Epub 2021 Apr 20.

Université catholique de Louvain, CHU UCL Namur, Department of Radiology, 1 Avenue Dr G Thérasse, 5530, Yvoir, BE.

Subgaleal lipoma is a benign tumor of adipose tissue. It should be suspected when a semi-spherical avascular mass with well-defined margins, iso- or hyperechoic in most cases, with thin internal echogenic lines parallel to the long axis of the tumor, is observed between the galea aponeurosis and periosteum of the cranial bone. We report a series of cases of three patients who underwent surgical lesion excision and whose histopathological examination findings confirmed the diagnosis of lipoma. Read More

J Surg Case Rep 2021 May 4;2021(5):rjab162. Epub 2021 May 4.

Department of General Surgery, University of Saskatchewan, Saskatchewan, Canada.

Parietal peritoneal lipomas are a rare surgical entity with seven case reports in the published literature. Their aetiology remains nebulous and includes theories such as misplaced embryonic tissue, adipose hyperproliferation, trauma and fat herniation or excessive obesity. This is the first case report in the literature with two parietal peritoneal lipomas incarcerated in an umbilical hernia. Read More

Approach to a patient with monoarticular disease.

Autoimmun Rev 2021 May 7:102848. Epub 2021 May 7.

Rheumatology Unit, Bnai-Zion Medical Center and Technion, Haifa, Israel; Ruth & Bruce Rappaport Faculty of Medicine, Technion, Haifa, Israel. Electronic address:

Purpose: To reassess the diagnostic approach to a patient with a monoarticular disease in light of the up-to-date medical literature and to examine the practical utility of traditional and newer imaging tools in the setting of monoarthritis.

Results: The monoarticular disease can represent a medical emergency on the one hand and be a diagnostic conundrum on the other. The management rules of patients with monoarthritis have been established long ago, but various pitfalls still lead physicians off the right diagnosis at times. Read More

Cureus 2021 Apr 6;13(4):e14321. Epub 2021 Apr 6.

Unit of Gastroenterology and Digestive Endoscopy, Sandro Pertini Hospital, Rome, ITA.

Colonic lipomatous polyps are often an incidental finding during colonoscopy. Generally, these types of polyps can cause gastrointestinal bleeding when they are larger than 4 cm in size. Some case reports have documented the occurrence of overlying adenomatous formations in the apical portion, as well as ulcerated mucosa. Read More

Large intraperitoneal lipoleiomyoma in a pre-menopausal woman: a case report.

World J Surg Oncol 2021 May 8;19(1):144. Epub 2021 May 8.

Department of Surgery, University of Michigan School of Medicine, 1500 E. Medical Center Drive, Ann Arbor, Michigan, 48109-5932, USA.

Background: Lipoleiomyoma is a rare, benign variant of the commonplace uterine leiomyoma. Unlike leiomyoma, these tumors are composed of smooth muscle cells admixed with mature adipose tissue. While rare, they are most frequently identified in the uterus, but even more infrequently have been described in extrauterine locations. Read More

A case of endobronchial actinomycosis as a challenging cause of lung atelectasis.

BMC Infect Dis 2021 May 8;21(1):433. Epub 2021 May 8.

Pulmonology and RICU, S Donato Hospital, Arezzo, Italy.

Background: Primary endobronchial actinomycosis is exceptionally uncommon and can be misdiagnosed as unresolving pneumonia, endobronchial lipoma, bronchogenic carcinoma or foreign body. Predisposing factors are immunosuppressive conditions, chronic lung diseases, poor oral hygiene or foreign body aspiration.

Case Presentation: We reported a case of 88-year old woman with a 4 days history of mild exertional dyspnea, productive cough with purulent sputum and fever up to 37. Read More

Imaging of intracranial fat: from normal findings to pathology.

Radiol Med 2021 May 5. Epub 2021 May 5.

Department of Diagnostic and Interventional Neuroradiology, E.O. Ospedali Galliera, Mura delle Cappuccine 14, 16128, Genoa, Italy.

The presence of intracranial adipose tissue is often overlooked, although it may be detected in different physiological (dural sinuses or falx deposition of fat) and pathological (lipoma, dermoid cyst, subarachnoid fat dissemination) conditions. In this review, we illustrate various scenarios in which radiologists and neuroradiologists may encounter intracranial fat, providing a list of differential diagnosis. Read More

Maximal Resection of Intramedullary Lipoma Using Intraoperative Ultrasonography: A Technical Note.

Acta Med Okayama 2021 Apr;75(2):239-242

Department of Orthopaedic Surgery, Okayama University Hospital.

One of the problems during surgery for intramedullary lipoma is the ambiguous boundary between the lipoma and the spinal cord, resulting in either incomplete resection or damage to the spinal cord. We report a case of intramedullary lipoma resection on a 61-year-old man in which the boundary between the tumor and spinal cord was repeatedly visualized with intraoperative ultrasonography. We focused on the distinctive features of fat as hyperechoic, in contrast to low-echo neural tissue. Read More

Acta Biomed 2021 Apr 30;92(S1):e2021084. Epub 2021 Apr 30.

University of Padova.

An intraosseous lipoma is considered one of the rarest primary bone tumors. The etiology of this lesion remains unclear; many lesions are asymptomatic and appear only as incidental findings during routine radiographic evaluations. Magnetic resonance imaging of intraosseous lipomas can help to establish a diagnosis and to stage the neoplasm. Read More

Department of Radiology, Division of Musculoskeletal Radiology, NYU Langone Health, 301 E 17th St, 6th Floor, New York, NY, 10003 (B.W., C.B., R.S.A.); and Department of Musculoskeletal Imaging, Hôpital Lariboisière, Paris, France (L.P.).

Purpose: To train convolutional neural network (CNN) models to classify benign and malignant soft-tissue masses at US and to differentiate three commonly observed benign masses.

Materials And Methods: In this retrospective study, US images obtained between May 2010 and June 2019 from 419 patients (mean age, 52 years ± 18 [standard deviation]; 250 women) with histologic diagnosis confirmed at biopsy or surgical excision ( = 227) or masses that demonstrated imaging characteristics of lipoma, benign peripheral nerve sheath tumor, and vascular malformation ( = 192) were included. Images in patients with a histologic diagnosis ( = 227) were used to train and evaluate a CNN model to distinguish malignant and benign lesions. Read More

Sialolipoma of the Floor of the Mouth with Immunohistological Analysis.

Case Rep Dent 2021 5;2021:6623045. Epub 2021 Apr 5.

Department of Oral Medicine and Diagnostic Sciences, King Saud University and University Dental Hospital, Riyadh, Saudi Arabia.

Lipomas are relatively rare in the head and neck, and sialolipoma was described as an entity about 20 years ago as lipoma that entraps salivary gland tissue. Less than 10 cases have been described in the floor of the mouth not related to the major salivary glands. Here, we report a case of sialolipoma affecting the floor of the mouth in a 47-year-old patient and reviewed the clinical, histologic, and immunohistochemical characteristics of the lesion.

An Unusual Cause of Adult Ileoileal Intussusception.

J Glob Infect Dis 2020 Oct-Dec;12(4):228-230. Epub 2020 Nov 30.

Institute of General Surgery, Madras Medical College, Rajiv Gandhi Government General Hospital, Chennai, Tamil Nadu, India.

Intestinal intussusception in adults is not considered to be common. Clinical presentations may range from an acute presentation to a chronic one and such wide variations make it challenging to establish the diagnosis on time. Adult intussusceptions usually have an identifiable pathological lead point: commonly a polyp, submucosal lipoma, or other tumors. Read More
