| PURPOSE : To evaluate the sonographic features of mesenteric lymphadenopathy in childhood epidemic aseptic
meningitis and to assess their clinical significance.
MATERIALS and METHODS : Thirty-three patients (25 male, 8 female; mean age, 8.6 years) with a diagnosis of aseptic
meningitis were prospectively evaluated with abdominal ultrasonography for the presence of enlarged mesenteric
nodes. The size and number of enlarged mesenteric lymph nodes were analyzed in relationship with the patient’s
age, between the patients with abdominal pain or diarrhea (16 cases, 48%) and asymptomatic patients
(17 cases, 52%).
RESULTS : Mesenteric lymphadenopathy was seen in 31 patients (94%), all 16 symptomatic and 15 of the 17 asymptomatic
patients. The number of enlarged nodes was most prevalent between 6-10, seen in 16 patients (52%)
and the largest node ranged in size from 4 to 8 mm. Among the 31 patients with mesenteric lymphadenopathy,
the mean size of the largest node was statistically different between the symptomatic (6.0 mm) and asymptomatic
(5.0 mm) groups (p = 0.021). The number of enlarged nodes and the patient’s age were not statistically different
between the two groups.
CONCLUSION : Mesenteric lymphadenopathy was seen in almost all cases of childhood epidemic aseptic meningitis,
and may be related to the mesenteric lymphadenitis caused by enterovirus. |
