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.

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.

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.

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.

Sparganosis is a kind of parasitic skin disease caused by sparganum, the plerocercoid larvae of the taper worm of the genus Spirometra. Sparganosis usually manifests as migrating or fixed subcutaneous nodules; therefore, it should be differentiated from lipoma, cysts, and cutaneous malignancies. Although the final diagnosis of sparganosis in humans depends on the identification of the worm in an infected tissue, suspicion for the presence of the parasite and careful history taking are important before making the diagnosis. However, it might be difficult for a clinician to suspect the existence of sparganosis because the incidence of this disease is extremely low. Therefore, an effective method for differentiating sparganosis from other skin disorders is needed. We suggest that ultrasonography could be an answer to this problem, on the basis of our experience of a case of cutaneous sparganosis in a 65-year-old woman showing very characteristic ultrasonographic findings.

PURPOSE: Sacral cutaneous lesions in newborns are associated with numerous spinal abnormalities. Early detection is important, because spinal abnormalities may cause neurological symptoms. Radiologic screening tests have been performed on newborns with sacral cutaneous lesions. This study aimed to substantiate the associations between sacral cutaneous lesions and spinal abnormalities. METHODS: From January 2007 until November 2013, we retrospectively reviewed the charts of 743 newborns with sacral cutaneous lesions that included sacral dimples, which were deeper than 5 mm and situated further than 2.5 cm from the anus, deviated gluteal furrow, hairy patch, hemangioma, dyspigmentaion, and the presence of mass, and skin tag. RESULTS: 743 newborns with sacral cutaneous lesions were examined, including 24 newborns with abnormal ultrasonographic images. Tethered cord which affected 18 (2.4%) of the newborns, was the most commonly found spinal abnormaility. Of these 9 newborns had other spinal abnormalities in addition to tethered cord including lipoma, cyst, spina bifida occulta, lipomyelomeningocele, and dermal sinus tract, and 9 newborns had isolated tethered cord only. Other spinal abnormalities found included isolated lipoma (3 newborns, 0.4%), and subarachnoid cyst (2 newborns, 0.3%), and of the 2 newborns (0.3%) who had dermal sinus tract, 1 also had a lipoma and the other also had a tethered cord. Normal variants included coccygeal pit (43 newborns, 5.8%), and ventriculus terminalis (10 newborns, 1.4%). Of the 646 newborns with isolated sacral cutaneous lesion, 11 (1.7%) had abnormal ultrasonographic images, and of the 97 newborns with combined sacral cutaneous lesions, 13 (13.4%) had abnormal ultrasonograpic images. CONCLUSION: Sacral cutaneous lesions in newborns can be associated with spinal abnormalities, and the strongest marker of spinal abnormality is a combined lesion. Therefore, ultrasonography should be performed on newborns who present with sacral cutaneous lesions to detect and investigate any underlying spinal abnormalities.

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.
