The value of CT in the diagnosis of tuberculous meningitis (TBM) in children is well reported. Follow-up CT scanning for these patients is, however, not well described and, in particular, the value of early follow-up CT has not been addressed for children with TBM. ⋯ Early follow-up CT is useful in making a diagnosis of TBM by demonstrating features that were not present initially and by demonstrating more sensitive, obvious or additional features of TBM. In addition, follow-up CT is valuable as a prognostic indicator as it demonstrates additional infarcts which may have developed or become more visible since the initial study. Lastly, follow-up CT has therapeutic value in demonstrating hydrocephalus, which may develop over time and may require drainage. We advise routine follow-up CT in patients with suspected TBM within the first week of initial CT and optionally at 1 month.

Case ReportsComplications of lumbar puncture in a child treated for leukaemia.
Lumbar puncture may lead to neurological complications. These include intracranial hypotension, cervical epidural haematomas, and cranial and lumbar subdural haematomas. MRI is the modality of choice to diagnose these complications. This report documents MRI findings of such complications in a child treated for leukaemia.

Sonographic detection of radiographically occult fractures in paediatric ankle injuries.
In some paediatric ankle injuries, the clinical picture is suggestive of a fracture despite negative three-view radiographs. ⋯ US is effective for the detection of radiographically silent fractures of the paediatric ankle. It may be used as an adjunct to radiography in clinically suspicious, but radiographically negative ankle injuries.

Case ReportsCecal volvulus: a rare cause of bowel obstruction in a pediatric patient diagnosed pre-operatively by conventional imaging studies.
Cecal volvulus is an acute surgical condition that is extremely rare in children, with a mortality rate of up to 40%. The clinical symptoms are often non-specific, and pediatric patients frequently have neurological deficits with associated communication difficulties, making the clinical diagnosis extremely challenging. Conventional radiographic imaging studies play a key role in the prospective diagnosis in children. We report a rare case of cecal volvulus in a 12-year-old boy who was diagnosed pre-operatively by abdominal radiographs and a contrast enema.

Case ReportsInterhemispheric lipoma connected to subcutaneous lipoma via lipomatous stalk.
Lipomas are rare intracranial lesions and are generally thought to be asymptomatic. The vast majority of intracranial lipomas are viewed as incidental findings on imaging studies and treated conservatively. ⋯ We report an infant with a subgaleal lipoma in the region of the anterior fontanelle connected to a large interhemispheric (pericallosal) lipoma via a tiny lipomatous stalk. Because of this association, infants who present with a subcutaneous lipoma of the scalp might be considered for MR imaging to evaluate for an intracranial component.
