RESUMO
Filariasis, a neglected tropical disease (NTD), is mainly caused by nematodes-Wuchereria bancrofti, Brugia malayi and B. timori Apart from profoundly disabling and disfiguring major clinical manifestations-lymphoedema, elephantiasis and hydrocoele-asymptomatic microfilaremia is common in endemic areas. Despite this, it is very rare to detect microfilariae in body fluids or aspirates. As per the literature search, this is the third case documenting incidental detection of microfilariae with metastatic deposits in the liver aspirate. Here, a 35-year-old man underwent image-guided fine-needle aspiration cytology of liver nodule. Liver aspirate cytology revealed poorly differentiated mucin-secreting metastatic carcinoma and coincidental presence of microfilariae of W. bancrofti Recently, microfilaria has frequently been found to be associated with the debilitated, immunocompromised condition and various neoplasm/cancer/malignancy. Hence, meticulous investigation should be undertaken to search for hidden pathology, whenever microfilariae are detected; and to deeply scrutinise aspirates for such parasites always, especially in endemic regions.

The authors describe the case of a 44-year-old male with chronic liver disease in whom celiacomesenteric trunk (CMT) was incidentally detected on routine multidetector row computed tomography of abdomen. The CMT (measuring approximately in diameter 12.3 mm) divided into celiac trunk and superior mesenteric artery (SMA) (measuring approximately 7.5 and 7.2 mm, respectively). The celiac trunk further divided into common hepatic, left gastric, and right inferior phrenic and splenic arteries. The common hepatic artery gave off gastroduodenal arteries before continuing as hepatic artery proper. The SMA was seen running down, deep to the neck of the pancreas to supply the midgut. The incidence and clinical implications of this vascular variation are discussed with a review of the relevant literature.

Anomalous preduodenal portal vein is a rare abdominal vascular variant; even rarer is the prepancreatic postduodenal position. We report an anomalous portal vein positioned in between duodenum and pancreatic head detected on contrast enhanced computed tomography. Awareness and accurate radiological interpretation of this unique and rare vascular pattern can prevent inadvertent injury during surgical and radiological interventions.
