Epidural Space Disorders
Epidural space disorder let in epidural infection , epidural hematoma or parentage clot , epidural abscess and spread of cancer in extradural space .
Epidural Space Occupying Lesions
The extradural space occupy lesions due to extradural haematoma , rakehell coagulum and spread of cancer development make wicked back hurting . Spinal epidural blank is also known as epidural space or peridural space . Epidural blank space is impound to hiatus magnum at the cephalic ( top ) end and sacrum at the caudal ( bottom ) end . It is the outmost anatomical place of spinal duct , which spreads within vertebral pillar . extradural space check lymphatic vessels , spinal nerve root , loose fatty tissue , arteries and epidural venous plexus .
Epidural Abscess
Epidural abscess , common epidural space disorder , is mostly located in cervical or lumbar epidural space . Epidural abscess follows contagion of epidural soft tissue.(1)Most of the abscess is because of staphylococcus aureus bacterial transmission . S. Aureus bacterial transmission is often triggered by introduction of contaminated needle or catheter in the extradural space during spinal or epidural anesthesia . Other bacterial infection , which may cause epidural abscess are Pseudomonas , E. Coli , Brucella and Mycobacterium .
TB . Rarely in a few cases the causa of abscess is found to be fungus contagion . Enlarged spinal epidural abscess causes compression or ischemia of spinal electric cord . As abscess expands , imperativeness is transferred to ancestry vessels , nerves and spinal electric cord within the epidural space .
Epidural Hematoma
Epidural hematoma is a rakehell clot within epidural space . The blood coagulum following bleeding within the epidural space . The blood clot is recognize as hematoma.(2)The injury of the blood watercraft within extradural outer space is due to sharp or blunt instruments . The interpolation of epidural phonograph needle or spinal needle during epidural or spinal anesthesia causes tear of vein or arteries in the epidural space . The amount of bleeding from epidural vein or artery depends on extent of bust . Larger the tear of artery or vein high the volume of bleeding and size of roue clot . Similarly , during operating theatre use of blunt or shrewd legal document for dissection of extradural space may stimulate injury of blood vessels resulting in extradural bleeding and hematoma . The extradural bleeding is also observed during following lash harm , fall or impact of hard object over back . The large volume of blood is discharged if individual is take blood cutting medication .
Epidural Cancer
Primary or metastatic epidural genus Cancer is extremely uncommon . Occasional extradural lipoma is keep in mediate aged patient . Lipoma is a benignant fatso tissue paper tumor . The metastatic malignant neoplastic disease from vertebral column may spread through the epidural infinite . The genus Cancer may broadcast rapidly through extradural space and do speedy neurological deterioration .
Symptoms and Signs of Epidural Space Disorders
Lab Studies to Diagnose Epidural Space Disorders
Abnormal Blood Examination-
Blood examination in most fount is normal .
WBC Count- periodic white pedigree cubicle enumeration is increased in patients suffering with epidural transmission and abscess .
ESR ( Erythrocyte Sedimentation Rate)- ESR is increased when patient is lose with epidural abscess and genus Cancer .
Blood Culture and antibiotic sensitivity test- The fluid collected from the extradural place is tested by bacterial growth and antibiotic sensitivity examination .
X - Ray- go - ray image shows bone development of metastasis or primary Crab of the vertebra .
Magnetic Resonance Imaging ( MRI)- MRI images of vertebra , extradural space and spinal cord differentiate malignant neoplastic disease ontogeny and fluid collection in epidural place . The mobile collection could be hematoma ( blood clot ) and abscess . The precise ranch of the malignant tumor , abscess and blood clot in extradural space can be diagnosed with MRI .
Disc Biopsy- Needle aspiration of the epidural abscess or blood clot is the authoritative trial run to distinguish reason of epidural infinite occupying wound . The science lab study distinguish the blood and abscess .
The malignant tissue paper is unmanageable to draw out with phonograph needle . The biopsy of the malignant tissue is performed following operative photo . The biopsy sampling are study for type of malignancies .
Ultrasound Studies- Ultrasound study differentiates mobile and solid ontogeny . echography study may not differentiate origin clot and abscess .
Differential Diagnosis of Diseases of Epidural Space
MRI- MRI image render evidence of epidural space occupying lesion . MRI differentiates extradural Cancer the Crab from extradural abscess and hematoma or rakehell clot .
Biopsy- Biopsy bailiwick of extradural space occupying lesion mark cancer , abscess and the blood line clot .
