Dorsal arachnoid web is a rare entity, which was rst reported by Malleci et al in 1997.It represents intradural, extramedullary band of arachnoid tissue that extends to the pial surface of the spinal cord which blocks the cerebrospinal uid ow in the longitudinal direction and widens the dorsal cerebrospinal uid space associated with increased pressure of the cerebrospinal uid & a local mass effect, resulting in the dorsal indentation and anterior displacement of the cord to cause myelopathy. Dorsal arachnoid web typically occurs in the upper thoracic spine

Orbital infection is an ophthalmological emergency as it can lead to blindness and intracranial spread. Imaging is needed to determine the extent of the infection, to detect complications and predisposing factors as well as for surgical planning. We report a case of a 7 year old boy who presented with a short duration history of nasal discharge, headache, fever with swelling and redness over the left eye. On local examination, the child had edema and erythema over the left eyelids, proptosis and painful restricted movements of the left eye. Imaging revealed extensive pansinusitis, marked axial proptosis of the left globe, marked stranding of the preseptal and orbital fat and a peripherally enhancing subperiosteal collection with central restriction in the extraconal space along the left orbital roof (Stage III Chandler classification of orbital infections).

Septo-optic dysplasia (SOD) is a neurodevelopmental disorder characterised by optic nerve and septum pellucidum dysgenesis as cardinal features. When septo-optic dysplasia occurs with other anomalies such as schizencephaly or callosal dysgenesis, it is called Septo-optic dysplasia plus syndrome. We report a case of 3 year old male patient who presented with global development delay and left sided weakness. Neurological examination revealed left hemiparesis and ophtalmological evaluation revealed right optic disc hypoplasia. The magnetic resonance imaging (MRI) showed absence of the septum pellucidum with right optic nerve and optic chiasma hypotrophy, bilateral open lip schizencephaly and polymicrogyria. On the basis of typical imaging findings, septooptic dysplasia-plus syndrome was implied as diagnosis. Despite major advances in diagnostic modalities including genetic studies, SOD still represent diagnostic challenges due to multifactorial and heterogeneous nature of the disorder. A life long multidisciplinary approach is helpful in management of these patients to optimise their growth and development
