ABSTRACT
Colonic adenomas are commonly encountered lesions that are a precursor of colorectal cancer. Of these, villous adenomas are a rarer, more advanced subtype that are larger in size than tubular adenomas and have a higher risk of malignant transformation. We present a patient with a giant villous adenoma of the sigmoid colon identified on CT as homogeneous segmental bowel wall thickening.
ABSTRACT
Kikuchi-Fujimoto disease is a rare, benign cause of necrotising lymphadenitis often presenting with fever. We describe a case of a 17-year-old boy with non-verbal autism presenting to our intensive care unit with prolonged fever of unknown cause. This case highlights the role of the intensive care unit in cases of diagnostic dilemma. The critical care community should be aware of Kikuchi-Fujimoto disease as although it is usually benign, it can rarely lead to acute airway compromise.

We present the unusual case of a 33-year-old woman who presented with a 2 year history of amenorrhoea and an expanding sellar lesion. Initial MRI revealed a lesion in the pituitary fossa, thought to be a pituitary adenoma. One year later, the lesion had enlarged by 5mm, with associated enhancement of the dura of the planum sphenoidale and pituitary stalk. Histopathology revealed a lymphocytic and plasma cell inflammatory infiltrate suggestive of lymphoplasmacytic hypophysitis associated with immunoglobulin G4.
