External infiltrating lipoma in a two‐week‐old foal: Computed tomographic evaluation for the assessment of the extension and invasiveness of the tumour

Abstract

Summary External lipoma is a benign subcutaneous and submucosal tumour and usually is of little clinical concern. Occasionally, the lipoma may invade muscles, the infiltrating lipoma. Complete surgical excision is mandatory because of the infiltrative nature and potentially high incidence of recurrence after inadequate surgery. In order to assess the extension of the tumour accurately, computed tomographic examination is indicated.

Diagnostic utility of computed tomography imaging in foals: 10 cases (2008–2010)

“…1997). Multi‐detector CT angiography was used to diagnose a parapharyngeal aneurysm (Powell 2010) and the extension and invasiveness of a lipoma was assessed by CT (Rebsamen et al . 2010).…”

“…Increasing numbers of case reports have been published using CT in foals (Ragle et al 1988;Cudd et al 1989;Clabough et al 1991;Kaneps et al 1995;Colbourne et al 1997;Tudor et al 1999;Van Hoogmoed et al 1999;Rosenstein et al 2000;Gull et al 2001;Kampmann and Stadler 2001;Wion et al 2001;Devine et al 2005;Bauer et al 2006;Janicek et al 2006;Waselau et al 2006;Wong et al 2006;Milligan and Biller 2007;Munsterman et al 2007;Stewart et al 2007;David et al 2008;Paradis 2010;Powell 2010;Rebsamen et al 2010;Roberts et al 2010;Van Galen et al 2010;Trump et al 2010;Morresey et al 2011) although a comprehensive assessment of the diagnostic utility has not previously been made. The purpose of the present study was to assess the diagnostic utility of CT in foals at our referral hospital and to compare it with published case reports.…”

Caecal lipomatosis as a cause of colic in a 9‐year‐old gelding

“…1993), thoracic wall and stifle (Bristol and Fubini 1984), neck (Blackwell 1972; Dunkerley et al . 1997) and back (Rebsamen et al . 2010) have been reported only in horses up to and including age 2 years.…”

Lipoma and infiltrative lipoma: A diagnostic dilemma

“…1993). Computed tomography has been described to separate lipomas from infiltrative lipomas in dogs (McEntee and Thrall 2001) () and now horses (Rebsamen et al . 2010).…”

“…Although recurrence has not been described in horses (Bristol and Fubini 1984; Lepage et al . 1993; Rebsamen et al . 2010), this is likely due to the low numbers of cases in the literature, the large area that is able to be resected on horses or perhaps the fact that the tumour has different characteristics of malignancy compared to what is seen in small animals.…”
