Abstract
F-:’·Ca 1 lesions of the liver are not uncomrnon and
are not easily diagnosed cl inicaly. It is not uncommon
to discover accidentaly focal lesions in the liver in
patinets during an abdominal ultrasound examination for
causes not related to hepatic disease at all. Also we
are sometimes confronted with patients with stones 1n
the gcd l bladder or biliary tree presenting as
epigastric and\or right hypochondria! pain and
ultrasonography was the only mean for detecting such
lesions.
The a1m of our work was to assess the value of
ultrasonography in the detection of hepatic focal
lesions in patients presenting with or without
hepatomegaly, also to assess its value in the detection
of organic hepatobiliary lesions in patients presenting
with epigastric and/or right hypochondria! disorders. To
do so 80 patients were chosen from the inpatients of
Tropical Medicine Department during the period from 1987
to 1990.
Patients were divided into 3 groups.
comprised 20 patients with hepatomegaly
227
group I
without complaint, group II comprised 20 patients with right
hypochondria! and/or epigastric pain with or without
hepatomegaly, group III comprised 40 patients with right
hypochondria! and/or epigastic pain with or without
hepatomegaly (as group II), but the difference 1s that
these cases were selected patients to have lesions.
In group I ultrasonography was able to detect
hepatic focal lesions in 8 patients (40%) while the
other 12 had no focal lesions, and, by the help of
guided liver biopsy the final diagnosis was reached.
In group II ultrasonographic examination was of
help 1n detecting and diagnosing the cause of right
upper quadrant pain 1n 50% of cases, 3 (15%) being due
to gall bladder lesion, 3 (15%) due to HCC, 2 (10%) due
to lymphoma. 1 (5%) due to haemangioma and another case
due to fatty infiltration.
In group III we tried to outline the common cause
of right upper quadrant pain in the patients presenting
to us during the period of this study and was found to
be:
• Gall bladder lesions
*Hepatocellular carcinoma (HCC)
* Metastatic liver d1sease
• Liver abscess
* Lymphocytic lymphoma
• Cancer head of pancreas
* Adult polycystic disease
