Ultrasound detected a plexus of vascular, serpiginous
structures in the porta hepatis anterior to the portal vein, and a provisional diagnosis of hepatic vascular malformation was considered.
Superior mesenteric artery angiogram showed abnormal serpiginous
vessels in relation to the right colic artery.
Features that favor PTLD over reactive lymphoid infiltrates are the following: expansile nodules or a mass lesion, numerous transformed cells, lymphoid atypia, predominant B-cell or plasma cell infiltrate, serpiginous
necrosis in the infiltrate, and/or the presence of numerous EBV-positive cells.
Sonographic findings include multiple hypoechoic, serpiginous
, and tubular intratesticular structures of various sizes with low-level internal echoes.
These were well-circumscribed cystic lesions with predominantly fluid-signal intensity containing linear serpiginous
low signal line is often present at the margin of the lesion, delineating the necrotic area from the adjacent area of bone marrow edema.
Skin prick and intradermal skin testing, using Fisher's Protocols (2), confirmed Gelofusine as the causative agent with marked serpiginous
weals with surrounding flares developing at both Gelofusine test sites.
In addition EV should be differentiated from the Chiari network, a highly mobile serpiginous
membrane, which is not attached to IVC.
Physical examination showed 2 elevated, ulcerative lesions on the lateral side of the right foot, and from each originated an elevated serpiginous
lesion (Figure, panels B and C).
However, approximately one-third of HAE patients may have a nonraised serpiginous
rash preceding angioedema attacks.
Pattern A, which is seen in acute HIV infection, is characterized by serpiginous
and greatly enlarged lymphoid follicles with reactive germinal centers (figure 1).
Positive findings were reported in 47% of the study population and included angiodysplasias, aphthoid and serpiginous
ulcers, active bleeding, varices, stenosis with ulcers, tumor, bleeding ileal polyps, gastric ulcers and GAVE (gastric antral vascular ectasia.
