RESUMO
We report the clinical details and imaging findings for a case of nondecussating retinal-fugal fiber syndrome or isolated achiasma in a 4-year-old female child. Findings included the isolated absence of optic chiasm with unremarkable rest of the optic pathway and midline structures in a child presenting clinically with see-saw nystagmus. Clinically congenital see-saw nystagmus, "mirror reversal" of visual field representation and interocular ipsilateral asymmetry on monocular visual evoked potential point toward achiasma and warrant further evaluation with magnetic resonance imaging (MRI). Isolated achiasma is a rare condition that may remain undiagnosed unless MRI is done.

We report the clinical details and imaging findings of a case of perforated Littre's hernia presenting as lower abdominal wall cellulitis in a 50-year-old male. Findings included herniation of an oral contrast opacified blind-ending pouch arising from the anti-mesenteric border of the distal ileum into the right inguinal canal, with extravasation of oral contrast. There were adjacent inflammatory changes with subcutaneous emphysema extending up to the right anterior chest wall. Meckel's diverticulum is rarely diagnosed preoperatively on imaging. We highlight the importance of computed tomography in imaging Meckel's diverticulum.

We report the clinical details and imaging findings for a case of vesicovaginal reflux presenting as gross urocolpos in a 15-year-old female. Findings included a large fluid-filled vagina on full-bladder scan in the absence of any anatomical abnormality, which disappeared completely after micturition. It is important for radiologists to be aware of this entity as it is rarely encountered and leads to very confusing findings, which could result in an erroneous diagnosis.
