Currarino triad: characteristic appearances on magnetic resonance imaging and plain radiography.

The Currarino triad is a complex anomaly consisting of an anorectal malformation, a sacral bone defect and a presacral mass. It was first described in 1981 and since then, approximately 250 cases have been reported. Radiology has an important part to play in the diagnosis of this entity, as the imaging features are characteristic. We report a case of Currarino triad in an infant who presented with intractable constipation and discuss relevant MRI and plain radiography findings.

Clinico-radiological presentation of squamous cell carcinoma of the mouth at Kenyatta National Hospital.

Clinico-radiological features of 17 patients with squamous cell carcinoma (SCC) of the oral cavity presenting at Kenyatta National Hospital (KNH) were studied. It was found that this tumour affects more males, with the buccal mucosa being the commonest intraoral site of origin. The right half of the mandible is the commonest bone involved and the tumour is destructive in nature, with the extent of destruction dependent on the degree of differentiation. Some of the newer imaging modalities used for the diagnosis of this tumour are also discussed.

Clinico-radiological aspects of dentigerous cysts.

The clinico-radiological features of 10 dentigerous cysts occurring in 6 patients are described. Dentigerous cysts are odontogenic cysts and may present directly as a painless jaw swelling or indirectly as an unerupted tooth. Radiologically, these cysts present as a pericoronal unilocular expansile translucencies the width of which exceeds 2.5 mm, with mandibular involvement predominating. Radiology plays an important role in detecting multiple cysts in a case presenting with a single cyst and also in detecting clinically asymptomic cysts in cases with delayed or non eruption of the teeth.
