A 62-year-old man with a history of hereditary spherocytosis had an abnormal shadow on a chest X-ray film, but the shadow was not examined further. The patient was admitted to our hospital because of severe anemia, multiple gallstones, and splenomegaly.
Acute cholecystitis
developed due to gallstones. A smear of peripheral blood showed spherocytosis, and the osmotic fragility as measured by Parpart's method was abnormally high. These findings are consistent with hereditary spherocytosis. Splenectomy and cholecystectomy were done. The chest X-ray film, CT scan, and
MRI
revealed multiple well-demarcatd paravertebral masses. A biopsy of a mediastinal mass was done with an ultrasonically guided needle, and hyperplasic erythroid hemopoietic tissue was obtained. This finding led to the diagnosis of extramedullary hematopoeisis. We think extramedullary hematopoeisis should be included in the differential diagnosis of posterior mediastinal masses.

Our purpose was to prospectively compare
MRI
findings with histopathologic findings in the evaluation of suspected
acute cholecystitis
. Fourteen patients with clinically suspected
acute cholecystitis
were entered into the study. MR sequences included T1-weighted fat-suppression and breath-hold spoiled gradient echo (SGE) before and after intravenous gadolinium chelate administration. Percent contrast enhancement (%CE) of the gallbladder wall and gallbladder wall thickness (WT) were measured and liver enhancement patterns determined prospectively on MR images. Correlation was obtained with pathological findings at cholecytectomy in all patients. In a second phase of the study MR images on 10 additional subjects who underwent MR examination for reasons other than hepatobiliary disease were analyzed to determine normal values for %CE and gallbladder wall thickness. Mean %CE was 124.0% in patients with
acute cholecystitis
(10 patients), 58.0% in patients with chronic cholecystitis (2 patients), and 73.0% in patients with gallbladder malignancy (2 patients). Mean gallbladder WT was 6.1 mm in
acute cholecystitis
, 4.5 mm in chronic cholecystitis, and 6.0 mm in malignant disease. There was a significant difference in %CE between acute and chronic cholecystitis (p = 0.03); no other significant differences in %CE or WT were observed among the patients with gallbladder disease. Patients without biliary disease had %CE of 37.3% and WT of 2.9 mm, which were both significantly less (p < 0.001) than in patients with
acute cholecystitis
. Transient enhancement of pericholecystic hepatic parenchyma on immediate postgadolinium SGE images was seen in 7 of 10 patients with
acute cholecystitis
, and not observed in other patients. Patients with
acute cholecystitis
had increased %CE and WT on MR images that were significantly greater than normal and %CE that was significantly greater than in patients with chronic cholecystitis. Transient increased pericholecystic hepatic enhancement was observed in 70% of
acute cholecystitis
patients and in no other patient groups.

A 61-year~old woman was admitted to the hospital with clinical manifestations of Cushing's syndrome. The ACTH level was 1340 pglmL, the urinary free cortisol level > 900 pg/mL, and the serum K+ levels 21 meqlL. The brain/pituitary
MRI
and thoracic CT scan were normal. Gastroscopy, colonoscopy, and small bowel follow through were normal. Abdominal CT and
MRI
showed normal adrenals, but dilated gallbladder with numerous gallstones, as well as peripancreatic and hepatoduodenal lymphadenopathy. A large meta-static deposit and three smaller lesions were also seen in the liver. Because of the poor respiratory function tests and the severe hypokalaemia, laparoscopy under local anaesthesia was performed. Following the procedure the patient became gradually jaundiced and thus underwent exploratory laparotomy. Locally advanced cholangiocarcinoma was found, infiltrating the liver hilum, with multiple small bilateral liver metastatic deposits.
Acute cholecystitis
with pericholecystic abscess was also found. Cholecystostomy as well as gallbladder, liver and hilar node biopsies were performed. Histopathology showed liver adenocarcinoma of bile duct origin, while immunocytochemistry revealed scattered, chromogranin A positive cells, some of them strongly immunoreactive for ACTH. Small clusters of chromogranin A positive cells were also found to be immunoreactive for CRH, but not for ACTH.

We report diffusion-weighted magnetic resonance imagings (DWI) at the acute stage of two patients with spectacular shrinking deficit (SSD) due to cardioembolic stroke. Patient 1 was a 74-year-old woman with atrial fibrillation (Af) who had been admitted for
acute cholecystitis
. She abruptly developed consciousness disturbance, global aphasia and right hemiparesis. Her neurological symptoms rapidly improved 30 minutes after onset, and completely disappeared in four hours. Patient 2 was a 84-year-old woman with Af who had been on medication of warfarin potassium for three years. She abruptly developed consciousness disturbance and left hemiplegia. Her neurological symptoms rapidly improved 90 minutes after onset, and almost completely disappeared in ten hours. Their conditions were consistent with SSD in acute cardioembolic stroke. DWI of Patient 1 taken 27 hours after onset showed hyperintense signal areas in the insular and temporal cortices of the left middle cerebral artery territory, and in the parietal cortex corresponding to the border zone between the territories of the left middle cerebral artery and posterior cerebral artery. DWI of Patient 2 taken 39 hours after onset showed hyperintense signal areas in the insular and frontal cortices of the right middle cerebral artery territory, and in the parietal cortex corresponding to the border zone between the territories of the right middle cerebral artery and posterior cerebral artery. They indicated multifocal ischemic injuries at the acute stage. The T2-weighted
MRI
of Patient 2 showed a slight hyperintense signal area only in the right parietal cortex, but the fluid-attenuated inversion recovery (FLAIR) in both patients showed no abnormal signals in the corresponding areas. To our knowledge, ischemic lesions in DWI of SSD at the acute stage after rapid recovery have not been reported previously. DWI is useful in SSD for detecting ischemic injuries of cardioembolic origin at the early stage.

Pyogenic abscesses of the liver represent a serious nosologic unit with high morbidity and mortality rates. Their diagnostics is based on ultrasonography, computer tomography or
MRI
, or positrone emission tomography. The principal treatment procedure includes percutaneous draining of the abscess cavity under the ultrasound or CT control. The authors present a group of 83 subjects hospitalized from 2000 to 2006 for pyogenic abscesses of the liver. Obstruction of the bile ducts,
acute cholecystitis
and resections of the liver or pancreas for malignancies were recorded as the commonest causes of the abscesses. Percutaneous drainage was the treatment method of choice in 67.5% of the subjects and it included management of the causative factors and administration of antibiotics. The hospitalization period was affected by the following factors: septic conditions (p < 0.04), ALT levels (p < 0.003) - cut off 3.0 mkat/l, the abscess diameter, which may have required reoperation, (p < 0,05), diabetes mellitus (p < 0.05) and septic conditions (p < 0.001). The need for re-hospitalization due to a relaps of the pyogenic abscess of the liver correlated significantly with the following: a number (> 2) of abscesses (p < 0.04), C-reactive protein levels (p < 0.005) - cut off> 100 mg/l and septic conditions (p < 0.007). Furthermore, significat correlation was detected between the mortality rates and sepsis (p < 0.05).

We report on a case of a female patient diagnosed with inflammatory pseudotumor of the liver in association with spilled gallstones 3 years after laparoscopic cholecystectomy for calculous
acute cholecystitis
. She was asymptomatic, but CT revealed an intrahepatic mass and two other extrahepatic masses between the liver and the diaphragm. Furthermore, diffusion-weighted
MRI
and PET suggested all three lesions could be malignant tumors. As the preoperative diagnosis was intrahepatic cholangiocellular carcinoma with peritoneal disseminations, we performed a posterior segmentectomy of the liver combined with partial resection of the diaphragm. Histological examination showed the intrahepatic tumor was an inflammatory granuloma with abscess formations. There were bilirubin stones between the liver and the diaphragm. Therefore, the tumor was diagnosed as inflammatory pseudotumor of the liver in association with spilled gallstones. In conclusion, the liver tumor emerged after laparoscopic cholecystectomy and may involve inflammatory pseudotumor of the liver in association with spilled gallstones.

We compared individual computed tomography (CT) and
MRI
findings in differentiating acute from chronic cholecystitis. Thirty-seven patients undergoing both studies before cholecystectomy were included. Two radiologists (R1/R2) independently assessed all cases. For detecting
acute cholecystitis
,
MRI
showed better sensitivity (R1) using gallbladder wall thickening, accuracy (R1) and sensitivity (R1) using gallstones, sensitivity (R1 and R2) and accuracy (R2) using gallbladder wall hyperemia, accuracy (R1 and R2) using gallbladder wall defect, and accuracy (R2) using adjacent liver hyperemia (P=.004-.063).
MRI
also showed better specificity (R2) using pericholecystic fat stranding (P=.016). Overall, several findings showed better sensitivity and/or accuracy for
acute cholecystitis
on
MRI
than CT.

Acute right upper quadrant pain is a common presenting symptom in patients with
acute cholecystitis
. When
acute cholecystitis
is suspected in patients with right upper quadrant pain, in most clinical scenarios, the initial imaging modality of choice is ultrasound. Although cholescintigraphy has been shown to have slightly higher sensitivity and specificity for diagnosis, ultrasound is preferred as the initial study for a variety of reasons, including greater availability, shorter examination time, lack of ionizing radiation, morphologic evaluation, confirmation of the presence or absence of gallstones, evaluation of bile ducts, and identification or exclusion of alternative diagnoses. CT or
MRI
may be helpful in equivocal cases and may identify complications of
acute cholecystitis
. When ultrasound findings are inconclusive,
MRI
is the preferred imaging test in pregnant patients who present with right upper quadrant pain. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel. The guideline development and review include an extensive analysis of current medical literature from peer-reviewed journals and the application of a well-established consensus methodology (modified Delphi) to rate the appropriateness of imaging and treatment procedures by the panel. In those instances in which evidence is lacking or not definitive, expert opinion may be used to recommend imaging or treatment.

Impacted common bile duct (CBD) lithiasis poses therapeutical challenges and repeated attempts of removal may result in life-threatening complications. CASE REPORT. A 45 year-old female patient was admitted in emergency for right upper quadrant abdominal pain and jaundice. Clinical, lab data, abdominal ultrasound (US) and cholangio-
MRI
established the diagnosis of
acute cholecystitis
and obstructive jaundice due to distal CBD lithiasis. Endoscopic retrograde colangiopancreatography (ERCP) confirmed the presence of a distal CBD stone but extraction failed. The patient was operated on and surgical procedure consisted of cholecistectomy, intraoperative cholangiography and a side-to-side choledocho-duodenal anastomosis was performed because all attempts to extract the stone through choledocotomy or duodenotomy and enlargement of endoscopic shincterotomy failed. The postoperative course was endangered by a severe pancreatitis, a massive upper digestive bleeding and portal vein thrombosis that responded to conservative management in the intensive care unit. The patient was discharged after 34 days in good clinical condition and approximately 9 months later was readmitted electively for an incisional hernia. Apart from this, physical examination, lab tests and imagistic studies were normal; the patient was operated and rapidly discharged in good condition. In conclusion, the management of CBD lithiasis may be a serious challenge both for interventional endoscopists and surgeons and require a concerted team effort.

When evaluating the abdomen in the emergency setting, CT and ultrasound are the imaging modalities of choice, mainly because of accessibility, speed and lower relative cost. CT has the added benefit of assessing the whole abdomen for a wide spectrum of gastrointestinal disease, whereas ultrasound has the benefit of avoiding ionizing radiation.
MRI
is another tool that has demonstrated increasing utility in the emergency setting and also avoids the use of ionizing radiation.
MRI
also has the additional advantage of excellent soft-tissue contrast. However, widespread use of
MRI
in the emergency setting is limited by availability and relative cost. Despite such limitations, advances in
MRI
technology, including improved pulse sequences and coil technology and increasing clinician awareness of
MRI
, have led to an increased demand in abdominal
MRI
in the emergency setting. This is particularly true in the evaluation of acute pancreatitis; choledocholithiasis with or without
cholecystitis; acute
appendicitis, particularly in pregnant patients; and, in some cases, Crohn's disease. In cases of pancreatitis and Crohn's disease,
MRI
also plays a role in subsequent follow-up examinations.
