A case report of calcifying pseudoneoplasm of the neuraxis: an incidental finding after a car accident

Abstract

Calcifying pseudoneoplasms of the neuraxis are rare, poorly understood lesions that can occur anywhere in the central nervous system without any age or sex predilection. Their pathogenesis is still controversial. Patients can present with various symptoms due to lesion location and only few cases have been discovered incidentally. We present a 25-year-old male referred to our hospital after a car accident. Computed tomography scan and magnetic resonance imaging was done because of the patient's head trauma and a calcified intracranial lesion was found and excised surgically. Pathologic evaluation of the specimen was consistent with the diagnosis of calcifying pseudoneoplasm of the neuraxis.

Surgically treated intracranial supratentorial calcifying pseudoneoplasms of the neuraxis (CAPNON) with drug-resistant left temporal lobe epilepsy: A case report and review of the literature

“…In the literature, there were 54 (60%) intracranial cases [3], [6], [7], [10], [16], [20], [24], [25], [26], [27], [28], [29], [31], [32], [33], [35], [36], [37], [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [50], [51], [52], [53], [55], [56], [57], [58], [59] and 36 spinal cases (40.0%) [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23] of CAPNON. Of the intracranial cases, 36 lesions were supratentorial [3], [6], [7], [10], [16], [20], [24], [25], [28], [29], [31], [32], [33], [35], [38], [40], [41], [42], [43], [44], [47], [50], [51], [52], [55]...…”

“…Calcifying pseudoneoplasms of the neuraxis (CAPNONs) are very rare lesions; only 90 cases including 54 (60%) intracranial cases and 36 (40%) spinal cases have been reported [1], [2], [3], [4], [5], [6], [7], [8], [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42], [43], [44], [45], [46], [47], [48], [49], [50], [51], [52], [53], [54], [55], [56], [57], [58], [59]. These lesions are benign and slow growing, and can present anywhere in the central nervous system, both intracranially and involving the spine.…”
