An algorithmic clinicoradiological approach to paediatric cranial vault lesions: distinguishing normal variants from pathologies.

Lesions of the paediatric cranial vault are diverse both in their presentation and aetiology. As such, they pose a diagnostic challenge to the paediatric neurosurgeon and neuroradiologist. In this article, we delineate the spectrum of paediatric calvarial pathology into four distinct groups: (1) lytic lesion(s); (2) focal sclerotic lesion(s); (3) diffuse cranial vault sclerosis; and (4) abnormal shape of the cranial vault. It is our aim that this more pragmatic, algorithmic approach may mitigate diagnostic uncertainty and aid the more accurate diagnosis of paediatric calvarial lesions.

A Cecal Lipoma Causing Intussusception, Detected on Routine Outpatient Abdominal Ultrasound.

This case reports on a patient presenting with abdominal pain of 1-month duration; in whom, ultrasound (US) detected a colonic lipoma with intussusception. Further investigation with computed tomography confirmed this finding, and successful endoscopic removal of the lipoma was performed. This case highlights the importance of careful evaluation of the region of interest during US, knowing the appearance of lipoma on US and other modalities, thus aiding its adequate management.
