The document discusses several radiology cases presented by Dr. Santhosh. It includes summaries of individual cases involving findings such as: 1) A gallbladder mass with local invasion and metastatic lesions in an abdominal imaging case. 2) Lucency seen over the liver on an abdominal x-ray of a renal transplant patient, which was later found to be biliary necrosis and abscess on CT scan. 3) Exercise-induced upper extremity deep vein thrombosis in 6 adolescent patients seen at a single center, who experienced poor outcomes with anticoagulation alone. 4) Additional cases involve findings such as diverticulitis, vein of Galen malformation, dandy walker cyst, and renal

 ? Differentials
 Teaching point is: There should be no lucency over liver, on plain xray .
 if its there then 4 possibilities Pneumobilia, portal vein gas, chilaiditi or
abscess.

In this renal transplant case abdomen xray showed this small irregular
LUCENCY over liver shadow,
 USG showed dirty shadowing with absent hepatic artery flow

16.  Upper-extremity deep venous thrombosis (UEDVT) is an increasingly important
clinical problem in children. These events are classified as primary or secondary,
with the latter being the most common and usually associated with the presence of
a central venous line. Among primary UEDVT, the so-called Paget-Schroetter
syndrome, effort-related or exercise-induced upper-extremity thrombotic event
represents an extremely rare finding that has never been described in a pediatric
series. The objective of the second part of this two-part article is to report the first
pediatric series in a group of adolescents with this condition from a single center,
describing their clinical features, management, and outcome. A retrospective chart
review of 6 patients seen between December 2003 and April 2005 was conducted,
with a median follow-up of 9 months (range 2-17). Four females and two males, all
Caucasian, were enrolled with a median age of 16 years (range 14-17). In all cases,
strenuous exercise was present in the month preceding diagnosis and mild trauma
was present in only one case (weight lifting). At presentation, all patients had
objective swelling of the affected limb for a median of 4 days (range 2-14), and 4
patients had UEDVT of the dominant arm. Thrombophilia investigation revealed that
50% had a combined prothrombotic state at presentation, and all patients were/are
being treated with anticoagulation for 6 months (low-molecular-weight heparin
followed by warfarin). Continuation of the initial symptoms was present in all cases
but one at the 3-month clinic follow-up (last case has yet to reach 3 months of
follow-up), and residual moderate to severe postthrombotic syndrome was present
in all 3 cases followed for more than 12 months. Of those 3 patients followed for
more than 1 year, 2 patients recurred despite having complete resolution of the
thrombus after 6 months of anticoagulation, and the third patient underwent
surgery with clinical improvement. Adolescents with UEDVT treated only with
anticoagulation seem to have a poor outcome.

 Dandy Walker malformation consists of a group of
anomalies where there is a posterior fossa
cyst communicates with the fourth ventricle, as well as
abnormal development of the cerebellar vermis.
 In its classical presentation consists of the triad of:
 Hypoplasia of the vermis and cephalad rotation of the
vermian remnant
 Cystic dilatation of the fourth ventricle extending
posteriorly. Usually the cerebellar hemispheres are
displaced anterolaterally, but with a normal size and
morphology
 Enlarged posterior fossa with torcular-lambdoid inversion

 1)Lateral radiograph of the lumbar spine shows
anterior scalloping of the vertebral bodies of L3 and
L4 and an indistinct L3-4 space. Vague curvilinear
calcifications anterior to the spine (arrow) are
related to an abdominal aortic aneurysm.
 2) Axial CT scan of the abdomen shows an abdominal
aortic aneurysm that has eroded the vertebral body.
There has been hemorrhage into the left side of the
retroperitoneum with loss of outline of the left psoas
muscle. Note also the “draped aorta sign”: an
unidentifiable posterior aortic wall and a posterior
aspect of the aorta that follows the vertebral
contour. The draped aorta sign is highly indicative of
aortic wall deficiency and a contained leak (,20).

==========================
Candida oesophagitis is usually identifi ed on
barium studies as discrete, linear, or irregular
plaque-like lesions separated by segments of
normal intervening mucosa – mainly in the upper
half of the oesophagus. In more advanced
disease, coalescent plaques may produce a
‘cobblestone’ appearance or, in severe cases
(usually in patients with AIDS), a grossly irregular
or shaggy oesophagus caused by extensive
plaque, pseudomembrane formation, intramural
haemorrhage and
ulcerations. In some cases, the disease can
present with mycetoma formation, which may
simulate an intramural neoplasm.
