This article presents a description of the ultrasonographic and computed tomographic findings with a discussion on the imaging features in three patients with epigastric hernias, simulating abdominal wall lipomas. Ultrasonogram showed a heterogeneous hypoechoic mass encircled by echogenic rim within subcutaneous space of the abdominal wall. Computed tomographic findings were a localized fatty mass surrounded by a thin capsule in as sociation with a focal discontinuity of the linea alba. Ultrasonogram was not diagnostic, but computed tomogram was suggestive because of the well demonstrated focal defect in linea alba.

Spindle cell/pleomorphic lipoma is an uncommon benign adipose tissue tumor most frequently arising from the subcutaneous tissue of the back, shoulder, head and neck, and extremities. The deep cervical spaces are the rarely affected locations. Herein we report on the imaging findings of spindle cell/pleomorphic lipoma involving the retropharyngeal space in an elderly woman.

BACKGROUND: Lipomas can be categorized into deep and superficial lipomas according to anatomical depth. Many cases of forehead lipomas are reported to be deep to the muscle layer. We analyze ultrasound in delineating depth of forehead lipomas. METHODS: A retrospective review was performed for all patients who underwent excision of forehead lipomas between January 2008 and March 2013 and for whom preoperative ultrasound study was available. Sensitivity and specificity of ultrasound imaging was evalauted against depth finding at the time of surgical excision. RESULTS: The review identified 42 patients who met the inclusion criteria. Preoperative ultrasound reading was 18 as deep lipomas and 24 as superficial. However, intraoperative finding revealed 2 of the 18 deep lipomas to be superficial and 13 of the 24 superficial lipomas to be deep lipomas. Overall, ultrasonography turned out to be 69% (29/42) accurate in correctly delineating superficial versus deep lipomas. CONCLUSION: Lipomas of the forehead tend to be located in deeper tissue plane compared to lipomas found elsewhere in the body. Preoperative ultrasonography of lipomas can be helpful, but was not accurate in identifying the depth of forehead lipomas in our patient population. Even if a forehead lipoma is found to be superficial on ultrasound, operative planning should include the possibility of deep lipomas.

Lipoma is one of the unusual benign breast neoplasms and usually manifests at fatty breast of women at the age of 40 to 60. We experienced a case of large breast lipoma nearly replacing the whole left breast parenchymal tissue with mammographic finding of well-defined radiolucent mass, sonographic finding of hyperechoic mass with disorganized echopattern and computerized tomographic finding of very low attenuation mass, characteristic to adipose tissue, in a young woman of her dense breast.

A gastrointestinal lipoma, though rare, is a mesencymal tumor of the large bowel, and the second most common benign colonic tumor detected after an adenomatous polyp. The lesion may be asymoptomatic when small and may be detected incidentally, usually during a colonoscopic examination for another purpose. Lipomas of the large bowel that are not causing symptoms probably need no treatment, as malignant transformation has not been documented. If the mass is large, it can cause pain, anal bleeding due to intussusception, bowel obstruction and diarrhea, and thus resection should be considered. Due to the risk of perforation, endoscopic resection of large colonic lipomas has been discouraged. However, large colonic lipomas can be removed safely by endoscopic resection with the use of an endoscopic ultrasonogram and submucosal injection to elevate the lesion.

Intraosseous hemangioma is a rare, slow-growing, benign tumor of blood vessels. Primary hemangioma of the skull is a benign lesion that may appear as a palpable mass or accidentally detected during image evaluation. Simple radiography is the most commonly used technique to localize a lesion and computed tomography (CT) may help determine the effect of a lesion. We report a case of multifocal intraosseous calvarial hemangioma developed in the subgaleal plane of an elderly male patient. Ultrasonography examination revealed hyperechoic striated septae parallel to the skin and discontinuity of the focal cortex, however, the underlying bone cortex appeared relatively intact. No significant flow is observed on Doppler ultrasonography. Based on these evaluations, the mass was interpreted by a radiologist as a subgaleal lipoma. This case highlights the importance of additional CT examination in a patient presenting with a scalloping sign of the underlying calvarium. Clinicians also should be aware of the possibility of intraosseous calvarial hemangiomas in lesion. Furthermore, the proper choice of congenital vascular malformation term is still quite confusing with misconception present in the literature.

Visceral lipoma originating from the mesentery is very rare in childhood. A 29-month-old male presented with painless abdominal distension. Abdominal ultrasonography and CT revealed a huge multilobulated hypodense mass in the peritoneal cavity. Exploratory laparotomy showed a 26 x 25 x 5 cm sized encapsulated, lobulated, homogenous mass, which originated from the transverse mesocolon. Histologic examination revealed a lipoma. The postoperative course was uneventful.

Most esophageal lipomas are discovered incidentally and are small and asymptomatic. However, large (>4 cm) lipomas may cause various symptoms, including dysphagia, regurgitation, or epigastric discomfort. We present a 45-year-old woman with intermittent sudden choking and globus pharyngeus. Upper gastrointestinal endoscopy and endoscopic ultrasound revealed an approximately 10.0×1.5 cm pedunculated subepithelial tumor in the upper esophagus, identified as the cause of her symptoms. A thoracic computed tomography scan revealed a fat attenuated longitudinal mass along the upper esophagus, suggestive of a lipoma. Endoscopic resection of the lesion was performed with a detachable snare to relieve her symptoms, and the pathologic findings were consistent with a lipoma.

Retroperitoneal lipoma probably constitute the group of the most massive solid abdominal tumors; their etiology is unknown; their symptoms insidious; and recurrence and sarcomatous change frequent. The clinical diagnosis was made by clinical symptoms, physical findings and radiologic evaluation such as intravenous urography, ultrasonography, computed tomography, angiography and so on. Abdominal CF scan provided clinically the most useful information regarding the state of tumors and also their effect on adjacent structures and shows homogenous appearing fat tissue with a low attenuation coefficient identical to that found in the subcutaneous fat. We present a case of treatment for a huge retroperitoneal lipoma in a 46-year-old man.
