Benign enlargement of sub-arachnoid spaces (BESS) is one of the causes of macrocephaly in infants. It is a self-limiting condition and does not require any active medical or surgical treatment. We report a case of an infant aged 4 months who was referred for magnetic resonance imaging (MRI) of the brain as the head circumference of the infant had increased rapidly from the 50th percentile in the 3rd month to more than the 95th percentile in the 4th month of age. MRI revealed enlarged anterior sub-arachnoid spaces and mild prominence of all the ventricles. A possibility of BESS was suspected since the child was neurodevelopmentally normal. A follow-up MRI done at the age of 18 months showed a reduction in the size of the sub-arachnoid spaces with normal sized ventricles.

Mature cystic teratoma (MCT) is the commonest germ cell neoplasm of the ovary but malignant transformation is a rare occurrence (1-2%). Of these malignancies documented in literature the commonest are squamous cell carcinoma and adenocarcinoma. Urothelial carcinomas arising in an MCT are a rare occurrence and only 7 cases have been reported in literature. We report a case of an MCT which was complicated by the presence of urothelial carcinoma confirmed on histopathological examination.

Longus colli calcific tendinitis is a rare condition which mimics the alarming condition, retropharyngeal abscess. Clinically, the patient presents which acute cervical pain, dysphagia and fever. Since this condition is little known to otorhinolaryngologists, it is usually misdiagnosed as a retropharyngeal abscess which is more common. This is a case report of a 52 year old female who presented with complaints of neck pain and difficulty in swallowing along with fever which were acute in onset. Clinically, the symptoms overlapped with those of a retropharyngeal abscess. The diagnosis was confirmed as longus colli calcific tendinitis. Longus colli calcific tendinitis is a rare entity which can be diagnosed solely based on radiological investigation. The knowledge of this disease is crucial to otorhinolaryngolists as it avoids over treatment, unwarranted chance surgical exposure.
