Intestinal chondrolipoma: uncommon cause of bowel obstruction

Confluent Small Bowel Lipomatosis: A Rare Cause of Recurrent Abdominal Pain

Small intestine lipomatosis is rare but may be associated with pain, intussusception, and gastrointestinal bleeding. In this report, we examine the case of a 41-year-old man who had recurrent presentations to the emergency department with non-specific abdominal pain. Preoperative imaging suggested extensive infiltration of small intestine with macroscopic fat. At surgery, extensive and confluent small bowel lipomatosis were seen. The affected ileal segment was resected, and the patient remained symptom-free after surgery. Abdominal lipomatosis is a rare condition which can be completely treated by resection of the affected gut segment but is often unsuspected and difficult to diagnose. In this report, we describe a case with the most extensive lipomatosis on record with more than 70 cm of gut with confluent lipomatosis. Magnetic resonance Enterography (MRE) is a useful non-invasive diagnostic modality, although laparoscopy/laparotomy may be necessary for assessment of the extent of disease. Symptomatic cases should be treated with segmental small bowel resection, which is curative.

Chondrolipoma of the stomach

Chondrolipoma, a rare variant of a lipoma, is a benign mesenchymal neoplasm characterised by mature adipocytes with neoplastic hyaline cartilage formation. We describe the first case of a gastric chondrolipoma. The tumour was completely excised via laparoscopic gastric wedge resection with uneventful postoperative recovery. Histology of the tumour demonstrates mature adipose tissue and benign cartilage with patchy calcification.

Chondrolipoma of the Ankle in a Child: A Case Report

Chondrolipoma is an extremely rare variant of lipoma with cartilaginous metaplasia. The presence of nonlipomatous components can lead to a variety of entities in the differential diagnosis from the radiologic findings. We describe an unusual case of a chondrolipoma occurring in the right ankle of a 9-year-old female. Physical examination showed a 3.5-cm, elastic-hard, poorly mobile, nontender mass adherent to the Achilles tendon. Plain radiographs revealed a faintly calcified soft tissue mass without bone involvement. Magnetic resonance imaging showed a well-defined mass with 2 components with heterogeneous signal intensity, suggesting the coexistence of a fatty area and another nonlipomatous component. Marginal excision of the tumor was performed. Histologically, the tumor was composed of mature adipose tissue studded with islands of mature hyaline cartilage. Based on these findings, the tumor was diagnosed as a chondrolipoma. The patient had no evidence of local recurrence within 9 months of follow-up. To the best of our knowledge, this is the first case of chondrolipoma originating from the ankle in a child.

Intramuscular chondroid lipoma: magnetic resonance imaging diagnosis by 'fat ring sign'

BACKGROUND

Chondroid lipoma is an extremely rare variant of benign lipomatous lesions that is composed of lipoblasts, mature fat, and chondroid matrix. Although benign lipomatous lesions are the most common soft tissue tumors and imaging findings are often pathognomonic, there have been few reports describing the imaging features of chondroid lipoma.

CASE REPORT

We present magnetic resonance imaging (MRI) findings of a pelvic intramuscular chondroid lipoma in a 59 year-old man and describe a "fat ring sign" that may be useful to diagnose this rare tumor radiologically.

CONCLUSION

Magnetic resonance imaging findings of a chondroid lipoma may be heterogenous according to the distribution of the fatty and chondroid tissue. However, in the presence of "fat ring sign," radiologists should consider a diagnosis of chondroid lipoma preoperatively.

Chondrolipoma in the pelvic cavity: a case report

A chondrolipoma is an extremely rare form of a benign mesenchymal tumor containing mature cartilage and fatty tissue. Chondrolipomas may be found in almost any part of the body, particularly in the connective tissue of the breast, head and neck area, as well as in the skeletal muscle. However, to the best of our knowledge, chondrolipomas located in the pelvic cavity have not been reported. In this case report, we describe a case of a chondrolipoma in the pelvis, and show that it has its own characteristic imaging findings, which included the composition of fatty tissue and calcification in most parts, as well as some focal areas of chondroid tissue based on the CT and MR findings.
