Podpajczynówkowa

Podpajęczynówkowa is a Polish medical adjective used to describe something related to the subarachnoid space or to the arachnoid mater (pajęczynówka) of the brain and spinal cord. It agrees with the gender of the noun it modifies; feminine nouns take the form podpajęczynówkowa, masculine form is podpajęczynówkowy, neuter is podpajęczynówkowe. The term is common in anatomical, radiological, and clinical texts to denote location or relation to the subarachnoid space.

Typical uses include torbiel podpajęczynówkowa (arachnoid cyst) and przestrzeń podpajęczynówkowa (the subarachnoid space). The descriptor helps distinguish structures or findings that reside in or involve the subarachnoid space from those in other meningeal compartments.

Anatomy and clinical relevance: The subarachnoid space lies between the arachnoid mater and the pia mater and contains cerebrospinal fluid. Pathologies described with the feminine form include conditions affecting this space, such as arachnoid cysts. In imaging, surgery, and pathology, podpajęczynówkowa specifies that the feature is within the subarachnoid space.

Etymology: from pod- (under) + pajęczynówka (arachnoid) + -owa, forming feminine adjectives.
