Hydrocoele of the canal of Nuck in an adult female is a rare entity and analogous to hydrocoele in males. Its usual presentation is in children, and its occurrence in adults is very uncommon, more so of the hour-glass variety. We report a case of a 38-year-old woman presenting with a right inguinal swelling of 3-month duration. On physical examination, the swelling was non-tender, cystic and irreducible. There was no cough impulse. Ultrasonography and contrast-enhanced CT revealed a cystic swelling with clear contents in the right inguinal region. Surgery was performed with excision of the cyst. The histopathology report suggested flat mesothelium cells, confirming the diagnosis.

SUMMARYMild encephalitis/encephalopathy with a reversible splenial lesion (MERS) is a clinicoradiological entity with varied aetiologies and having a typical course of evolution. We present a case of MERS evaluated with diffusion-weighted and diffusion tensor imaging along with various conventional sequences of MRI. At the time of presentation, the lesions in the splenium of corpus callosum and bilateral cerebral white matter showed diffusion restriction with reduced apparent diffusion coefficient and no reduction in fractional anisotropy (FA) values on diffusion tensor imaging; on follow-up diffusion restriction completely resolved with normalisation of the apparent diffusion coefficient. The normal to slightly increased FA values in the lesions may indicate that MERS is a non-degenerative disorder. BACKGROUND

We present the case of a 48-year-old man who presented with a painless, progressively increasing lump in the left breast. The mammographic and sonographic appearance of the lesion was suspicious for malignancy. Fine needle aspiration cytology and histopathologic examination confirmed the diagnosis of pilomatricoma. © 2017 Wiley Periodicals, Inc. J Clin Ultrasound 46:209-211, 2018.
