Cavernous mesenteric lymphangiomatosis mimicking metastasis in a patient with rectal cancer: A case report

Abstract

Lymphangioma usually occurs in children and usually involves the skin. Mesenteric lymphangioma is extremely rare in adults. Typically, lymphangioma appears on computed tomography (CT) as a lower attenuation of a cystic mass, however, some cases appear to be a solid mass. We describe the CT and 18F-FDG positron emission tomography/CT appearance in a case of jejunal and mesenteric cavernous lymphangiomatosis mimicking metastasis in an adult patient with rectal cancer.

Mesenteric cysts in naevoid basal cell carcinoma syndrome: a mimic of metastatic disease

“…Serial CT imaging allows assessment of increase in lesion size suggestive of metastatic disease over benign cysts. Fludeoxyglucose‐labelled positron emission tomography scans also show lack of uptake in these cysts, which may serve as a useful adjunct in case of uncertainty 7. Notably, in our case smaller mesenteric cysts (Fig.…”

Abdominal lymphangiomas in adults: case report and literature review

“…Diagnostic methods, such as abdominal US and CT, are useful in diagnosing tumour, although cavernous lymphangiomas, which appear on CT as a solid mass, may be confused with metastases in patients with malignancy [2,10]. In our experience, all patients were diagnosed with a lymphangioma preoperatively.…”

“…The features of cavernous lymphangioma in US and CT imaging are a multilocular homogeneous mass, enhancement of the wall and septa, and the presence of a fluid [8][9][10] (Figures 1, 2). Calcification in lymphangiomas occurs rarely [5] (Figure 3).…”

“…On CT and US imaging, a cavernous lymphangioma may appear as a solid mass due to the microcystic nature, intracystic debris, or haemorrhage. In these cases, magnetic resonance imaging (MRI) is useful as it is more specific for detecting the cystic nature of cavernous lymphangioma [10]. MRI T1 weighted images show heterogeneous lesions, while T2-weighted images indicate cystic spaces filled with a fluid [8].…”

Lymphatic Angioma of Mesentery of the Small Intestine - A Case Report

“…other symptoms difficult for diagnosis are alimentary canal bleeding or symptoms suggesting acute appendicitis. They may be detected during laparotomy connected with another disease or exploratory laparotomy (6). Mesentery angioma diagnosis is based on imaging examination (ultrasound, CT, MRI, PET), which are rarely of decisive character (7,8).…”
