INTRODUCTION Benign musculoskeletal lipomatous lesions are common in both soft tissue and bone. Imaging features of benign lipomatous lesions are often pathognomonic. Ultrasound (US) has been used to examine both soft tissue and bone tumors, allowing targeted CT or MRI examination of the region of interest. CASE REPORT A 46-year-old female presented with a four year history of palpable mass l...

Lipomatous hypertrophy of interatrial septum (LHIS), usually found in echocardiography, is a rare non-neoplastic disease entity, which may cause arrhythmia or sudden death. We reported a case of LHIS associated with hypertrophic cardiomyopathy (HCM), which was suspected a hyperechoic intraatrial tumor in transthoracic echocardiography. Magnetic resonance (MR) imaging showed fat infiltration of ...

Lipoblastoma is an uncommon benign lipomatous tumor, occurring typically in children less than 3 years of age. The magnetic resonance image (MRI) is a useful tool for diagnosis of lipoblastoma; its imaging typically shows high-intensity signals on both T1-weighted (T1-W) and T2 weighted (T2-W) images. Here, we present a 12-year-old female patient with a painless mass on the anterior right shoul...

Lipoastrocytoma is an extremely rare tumor, with only six cases described. We report the case of an astrocytoma involving the upper part of the cerebellar-pontine angle and the right portion of the clivus starting from the brainstem with a diffuse lipomatous component in a 39 year-old man. The patient was admitted with headache of 1 year's duration and diplopia over the previous 3 months. MRI r...

Adipose fins are enigmatic appendages found between the dorsal and caudal fins of some teleostean fishes. Long thought to be vestigial, degenerate second dorsal fins, remnants of the primitive gnathostome condition, adipose fins have since been recognized as novel morphologies. Unique among the fins of extant fishes, adipose fins have uniformly been described as passive structures, with no asso...

Lipoma arborescens, a rare benign intra-articular lesion, is characterized by lipomatous proliferation of the synovium in which the subsynovial tissue is replaced by mature adipocytes. Subdeltoid bursa is a rare location for lipoma arborescens, and only a few cases have been reported in the literature. This article reports 2 cases of subdeltoid lipoma arborescens combined with rotator cuff tear...

A 50-year-old female presented with more than 20-year history of a large subcutaneous mass in the left parieto-occipital portion. Magnetic resonance (MR) imaging revealed the lipomatous mass to show a high signal intensity in both T1- and T2-weighted images. A part of the lipomatous lesion progressed into the underlying hyperostosis and skull. The preoperative diagnosis was skull invasion of a ...

Lipomatous hypertrophy of the interatrial septum (LHIS) is usually an incidentally detected benign disorder which is asymptomatic in most of the cases. On the other hand, cardiac lipomas are rare benign cardiac tumors. In transthoracic echocardiography (TTE) of a 77-year-old male patient, who was admitted with the complaint of dyspnea, homogeneous hypertrophic interatrial septum (IAS) was obser...
