Hepatic mesenchymal hamartoma: An uncommon but important paediatric diagnosis.

Hepatic mesenchymal hamartoma is a rare hepatic tumour seen in the paediatric population. Although this entity has a variable imaging appearance, it has a favourable prognosis if diagnosed and managed correctly. This case presents the ultrasound and computed tomography findings of an 11-month-old patient who presented with a history of progressive abdominal distension and an elevated alfa fetoprotein level on biochemistry.

Complicated spontaneous pneumoparotid mimicking a neck mass in a child with Down's syndrome.

Spontaneous or self-induced pneumoparotid, which usually manifests as acute unilateral gland enlargement, is caused by insufflation of air from the oral cavity via Stensen's duct. A 9-year-old patient, with known Down's syndrome, presented with a progressively enlarging, painless, spontaneous, left neck mass. Computed tomography showed features consistent with pneumoparotid, without underlying associated pathology.

Incidental amniocele in a case of antepartum haemorrhage.

An amniocele, or contained uterine rupture, is a phenomenon in which there is herniation of the amniotic sac through a uterine defect, secondary to various causes. It is associated with severe morbidity and mortality. This case presents the findings in a 36-year-old female at 29 weeks gestation who was initially managed as antepartum haemorrhage secondary to placenta previa, based on ultrasound.

Page kidney: A rare cause of secondary hypertension.

Page kidney is a rare phenomenon that can present with hypertension. The presence of a subcapsular perirenal collection causes parenchymal compression leading to renal hypoperfusion. Subsequent activation of the renin-angiotensin-aldosterone system results in an increase in systemic blood pressure.
