Summary

This study describes a rare, localized subdural hygroma in a man with a chronic skull mass and headache. The unique cystic lesion communicated with the subarachnoid space, presenting diagnostic challenges.

Area of Science:

  • Neurosurgery
  • Neurology
  • Radiology

Background:

  • Subdural hygromas are collections of cerebrospinal fluid in the subdural space.
  • They are typically associated with head trauma, particularly in infants.
  • This case presents a unique variant in an adult with a long-standing history.

Observation:

  • A 29-year-old male presented with a chronic skull mass and progressive headache over 6-7 years.
  • A history of an unrecognized skull fracture from a car accident 8 years prior was noted.
  • Surgical exploration revealed a localized, cystic subdural hygroma with a narrow communication to the subarachnoid space.

Findings:

  • The subdural hygroma was uniquely delineated by dural-arachnoid adhesions.
  • A clear communication pathway between the hygroma and the subarachnoid space was identified.

  • Localized skull bulging is an exceptional finding for subdural hygromas.

    • Implications:

    • This case expands the understanding of subdural hygroma presentations.
    • Accurate differentiation from other cystic lesions (e.g., arachnoid cysts, subdural hematomas) is crucial for diagnosis.
    • Highlights the importance of considering long-term sequelae of unrecognized head trauma.
