Bilateral femoral artery aneurysm mimicking soft tissue sarcoma.

Despite the rarity of femoral aneurysm and the plethora of other causes of swelling in and around its anatomic location, the possibility of its existence must always be borne in mind. A rare case of metachronously bilateral femoral aneurysms mimicking soft tissue sarcoma in a young Nigerian man is presented. Caution in the diagnosis of groin masses is hereby re-emphasized.

Giant neoplastic omental cyst masquerading as ascites: a case report.

INTRODUCTION: Cystic lesion of the omentum and mesentery are rare. The incidence of both cyst types has been variously reported to vary from 1/27,000-100,000 hospital admission. Omental cysts occur three to ten times less frequently than mesenteric cyst. Preoperative diagnosis is infrequently made because of lack of characteristic symptoms and signs. CASE PRESENTATION: We present our diagnostic and management challenges in a 43-year-old man with an unusually giant omental cyst confirmed as fibrosarcoma at histology. The cyst gave the abdomen an anteroposterior diameter of about 74 cm that could not be penetrated sufficiently by X-ray photons to produce diagnostic image even at maximum attainable output. Patient benefited from surgical excision. The removed cyst contained about 35 litres of fluid. CONCLUSION: Neglected omental cysts as in this case may grow to enormous size, undergo malignant transformation and poses serious diagnostic and surgical challenges.

Orocervical foetus-in-foetu with prenatal sonographic diagnosis: a case report.

INTRODUCTION: Foetus-in-foetu is a very rare congenital abnormality where a malformed foetus is included within the body of another foetus. Less than 200 cases have been reported with over 80% occurring in the abdomen. Only three cases of cervical foetus in foetu have been reported. The present case of giant orocervical foetus-in-foetu appears to be an index case. CASE PRESENTATION: This is a report of an extremely rare orocervical foetus-in-foetu with grotesque oddity diagnosed on prenatal ultrasonography at 35 weeks gestational age in a 28-year-old, G2P1+0, Nigerian woman who was unsure of her last menstrual date or month. The included foetus had two eyes, cranium, nose, long bones and a spine. The mother's attempts at vaginal delivery rather than the elective Caesarean delivery she was offered resulted in obstructed labour and intrauterine foetal demise. CONCLUSION: Giant cervical foetus-in-foetu is extremely rare. It could result in obstructed labour if vaginal delivery is attempted.
