MRI findings of postherpetic abdominal wall pseudohernia: A case report

Abdominal paresis and pseudo-hernia secondary to herpes zoster infection: A case report and systematic analysis

“…34 cases of abdominal pseudo-hernia due to herpes zoster infection were included. Their demographic data, clinical features, electrophysiological studies and imaging findings were summarized [ [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] ]. ( Table 1 , Table 2 ) The median age of the patients was 71.5 (43–82) years.…”

Postherpetic abdominal pseudohernia. Presentation of a clinical case and literature review

“…The diagnosis is primarily clinical, but complementary studies may be used in doubtful situations. Ultrasonography is useful to rule out visceral involvement in relation to compromise of the abdominal wall . MRI could be helpful in order to define the location and to delineate the extent of the inflammation, as well as to exclude other causes for motor paresis, such as tumors and radiculoneuropathies, among others …”

Abdominal pseudohernia caused by herpes zoster motor neuropathy

“…MRI can also identify changes which may point to the pathophysiology behind herpes zoster pseudohernia. The pathogenesis of herpes zoster pseudohernia is still not fully understood but the most common theory is that the virus spreads from the dorsal root ganglion to the nearby anterior horn cells or to motor nerve roots near the spinal cord 8,9 . This causes denervation of the related muscles and resulting paresis.…”

“…The pathogenesis of herpes zoster pseudohernia is still not fully understood but the most common theory is that the virus spreads from the dorsal root ganglion to the nearby anterior horn cells or to motor nerve roots near the spinal cord. 8,9 This causes denervation of the related muscles and resulting paresis. As MRI has demonstrated denervation of paraspinal muscles in patients with abdominal wall paresis, some have posited the point of inflammation causing the symptoms is proximal to the anterior and posterior rami.…”
