Splenic flexure colonic lipoma causing intussusception.

Colonic lipomas are rare benign tumours that are usually asymptomatic. However, giant colonic lipomas tend to be symptomatic and can occasionally result in intussusception and intermittent colonic obstruction. As adult intussusception is an uncommon occurrence, the identification of the underlying aetiology is essential due to its high association with malignancy. Computed Tomography remains the tool of choice for the diagnosis of colonic lipomas. Surgical excision remains the mainstay treatment of giant symptomatic colonic lipomas. We hereby present the case of a 51-year-old male found to have a colonic lipoma causing recurrent intussusception. We discuss the approach, diagnostic tools and available treatment modalities for colonic lipomas. We also provide a brief literature review of intussusception in adults.

Case report: Back pseudocyst of unknown origin.

INTRODUCTION: Soft tissue masses are fairly encountered clinical entities. Among the rare forms of soft tissues masses are non-pancreatic pseudocysts which are defined as encapsulated fluid collections not lined by epithelium. We are presenting a rare case of a pseudocyst of the back located within the paravertebral muscles at a tertiary care center. CASE DESCRIPTION: Patient presented with a progressively enlarging painless back mass. CT scan was done which showed a 10 × 10 cm cystic lesion along the paravertebral muscles of the back. Surgical excision of the mass was performed revealing an irregularly shaped multilocular cyst. Final pathology showed the lesion to be a pseudocyst. DISCUSSION: Pseudocysts can arise in a variety of locations such as omentum, adrenal glands, spleen or lungs. The etiology of these pseudocysts is highly variable and can be related to trauma, inflammation, or surgery. The diagnosis of these entities requires proper imaging and histopathologic examination. CONCLUSION: Pseudocysts arise due to a myriad of conditions and their diagnosis remains a challenge. Our case comprises the first reported case of idiopathic pseudocyst of the back. Although rare, pseudocysts should be considered in the differential of unexplained masses.
