AIM: To describe and discuss echo-enhanced sonography in the differential diagnosis of cystic pancreatic lesions. METHODS: The pulse inversion technique (with intravenous injection of 2.4 mL SonoVue) or the power-Doppler mode under the conditions of the 2nd harmonic imaging (with intravenous injection of 4 g Levovist) was used for echo-enhanced sonography. RESULTS: Cystadenomas frequently showed many vessels along fibrotic strands. On the other hand, cystadenocarcinomas were poorly and chaotically vascularized. "Young pseudocysts" were frequently found to have a highly vascularised wall. However, the wall of the "old pseudocysts" was poorly vascularized. Data from prospective studies demonstrated that based on these imaging criteria the sensitivities and specificities of echo-enhanced sonography in the differentiation of cystic pancreatic masses were >90%. CONCLUSION: Cystic pancreatic masses have a different vascularization pattern at echo-enhanced sonography. These characteristics are useful for their differential diagnosis, but histology is still the gold standard.
Non bacterial thrombotic endocarditis is the most frequent cause of ischemic stroke in cancer patients. Up to 9% of autopsies of cancer patients show non infectious valvular masses. However, bivalvular involvement is not frequently occurring in 9% of non bacterial thrombotic endocarditis. We report a patient with ovarian cancer who presented aphasia. The MRI was compatible with cerebral ischemia. The transthoracic echocardiogram was normal and a transesophageal echocardiogram showed vegetations in aortic and mitral valves. We emphasize the importance of suspecting non bacterial thrombotic endocarditis in patients with cancer and systemic embolism and the low frequency of bivalvular involvement.
BACKGROUND: Malignant fibrous histiocytoma is the most common sarcoma of soft tissue, which occurs usually in the extremities, but less common in the retroperitoneal space, abdominal cavity or other sites. Primary malignant fibrous histiocytoma of the liver is extremely rare; only 28 cases have been reported to date in the English literature. METHODS: In this report, a case of primary malignant fibrous histiocytoma of the liver was described in terms of clinical presentations, diagnosis and treatment and outcome. RESULTS: A 50-year-old man had a large multicystic-mass lesion in the left lobe of the liver, which was inoperable by laparotomy. Pathological examination of biopsy specimen after operation confirmed a malignant fibrous histiocytoma of storiform-pleomorphic type. The tumor developed rapidly, and the patient died of hepatic failure 2 months after the surgery. CONCLUSIONS: Primary malignant fibrous histiocytoma of the liver is diagnosed in late stage because of its rarity and non-specific presentations. Surgical resection, if feasible, is the first step treatment. The prognosis of primary malignant fibrous histiocytoma of the liver is grim with a median survival of 3 months as reported. Surgeons should be alert to the existence of this type of soft tissue tumor in the liver.
