BACKGROUND Location of an intrathoracic lesion on chest radiograph is facilitated by application of 'silhouette sign'. This helps narrow down the differential diagnoses. The list of probable diagnoses reduces further on determination of the density of the lesion. A spinal hydatid presents as a fluid-density posterior mediastinal lesion on chest radiograph with destruction of the vertebral body ...

Depressed skull fracture is an inward buckling of the skull bones, often because of direct blow to a small surface area of the skull with a blunt object. Monoparesis is often among its clinical presentations, but midline depressed skull fracture presenting as motor weakness of both lower limbs (Paraperesis) has not yet been reported. We report the case of 55 year old male admitted to emergency ...

Intradural extramedullary type of spinal hydatid disease is a rare variety of hydatid disease, and is even rarer in paediatric age group. Spinal hydatid disease should be considered in the differential diagnosis of spinal cord compression syndrome in endemic countries and should be evaluated with imaging and serological investigations. Our case was a 9- year-old boy who presented with lower bac...

Primary spinal hydatid disease is rare. Spinal hydatid disease should be considered in the differential diagnosis of spinal cord compression syndrome in endemic countries and evaluated with imaging and serology. Our case was a 34- year-old man. The patient presented with progressive back pain for 8 months and lower extremity weakness for 3 months. Neurological examination was suggestive of uppe...

Human T-cell lymphotropic virus type 1 (HTLV-1) is associated with a chronic neurological disease termed HTLV-1-associated myelopathy/tropical spastic paraperesis (HAM/TSP). Although the pathogenesis of this disease remains to be elucidated, the evidence suggests that immunopathological mechanisms are involved. Since HTLV-1 tax mRNA was colocalized with glial acidic fibrillary protein, a marker...

STUDY DESIGN Fifty patients surgically treated for tethered cord syndrome (TCS) were retrospectively studied at Liaquat National Hospital, Karachi from 2010 until 2014. PURPOSE To assess the common presentations of TCS in our part of the world and the surgical outcome of the different presentations. OVERVIEW OF LITERATURE TCS is a stretch-induced functional disorder of the spinal cord with ...

OBJECTIVE(S) The aim of this study was to investigate the association between HLA class I alleles (HLA-A*02, HLA-A*24, HLA-Cw*08, HLA-B5401) and proviral load in HTLV-I associated myelopathy/tropical spastic paraperesis (HAM/TSP) patients in Iranian population. MATERIALS AND METHODS 20 new cases of HAM/TSP patients and 30 HTLV-I infected healthy carriers were recruited. Peripheral blood sampl...

Background and Aims: Human lymphotropic virus type-1 (HTLV-1) causes various diseases such as adult T-cell leukemia/lymphoma (ATLL) and HTLV-1 associated myelopathy/tropical spastic paraperesis (HAM / TSP) in humans. The main goal of this study is to compare Iranian protease subtypes structure of this virus (HTLV-1) to samples collected from other part of world in order to understand their diff...

Traumatic spinal epidural hematoma (TSEH) is a neurosurgical emergency which is considered as one of the rare causes of back pain. The onset of symptoms presentation can vary especially following a trauma. Here, we report a case where a young girl had a trivial fall and presented symptoms of back pain three days later. She developed abrupt onset of lower limb weakness during her stay in the eme...
