Gemcitabine is the only cytotoxic agent approved by FDA for the treatment of pancreatic carcinoma. Gemcitabine has a relatively safe profile. Major side effects include bone marrow suppression and flu-like syndrome. Transient abnormalities of liver transaminase enzymes are seen in two third of patients: elevations of alkaline phosphatase and bilirubin are less common, but severe hepatic toxicity is uncommon. Four case reports regarding severe hepatic toxicity of gemcitabine leading to rapid deterioration in patients' health status and death have been reported. We report the fifth case in which liver functions were within normal limits but liver toxicity was preceded by radiological findings on the MRI. We describe a 61-year-old male with stage T4N1M0 who initially received gemcitabine-oxaliplatin (GemOx) regimen was switched to gemcitabine-capecitabine (every two weeks schedule) after four months of therapy due to lack of response. Restaging CT scan after eight-weeks showed new multiple foci of low attenuation resembling simple cysts. MRI of the abdomen was performed which revealed early and active fibrosis. Hepatitis panel were negative. Subsequently the patient developed nausea, vomiting, abdominal pain and weight loss and was referred for palliative radiotherapy. Gemcitabine was discontinued and follow-up CT scan two months later showed stable lesions in the liver. In conclusions, four cases of gemcitabine-induced liver toxicity has been reported in the literature. Such toxicity is manifested by elevated liver transaminases and more common in the presence of liver metastasis. However, our case showed that gemcitabine-induced liver toxicity can be detected by MRI, before liver enzymes start to rise and discontinuation of gemcitabine can prevent further liver toxicity and fibrosis. Report of such cases is encouraged as it will bring awareness among clinicians caring for such patients receiving gemcitabine.

Mercury intoxication is a rare cause of severe hypertension. A case of mercury intoxication presented with severe hypertension and erythromelalgia was reported. A 10-year- and -5-month-old girl presented with recurrent rash and painful hands for 2 months, with seizure attack and episodic loss of consciousness for one hand half months. The girl was found to have red painful hands, a blood pressure 170/120 mm Hg(1 mm Hg=0.133 kPa), tachycardia and hypokalemia (2.83-3.25 mmol/L, reference value 3.5-5.5 mmol/L). An extensive investigation ensued. Elevated renin-angiotensin and aldosterone were demonstrated in plasma. Cranial MRI T2 weighed images showed widespread white matter signal abnormalities, which particularly involved parietal, occipital and frontal lobes. With hypertension controlled, white matter signal abnormalities weakened. Other symptoms included insomnia, nausea and paroxysmal abdominal pain. The girl was found to have a raised concentration of mercury in urine (0.171 mg/L, reference value< 0.01 mg/L), and she had been exposed to elemental mercury for several days. After chelating therapy, the girl's blood pressure returned to normal, erythromelalgia ameliorated, all other symptoms disappeared. So, mercury intoxication should be considered in the differential diagnosis of hypertension with erythromelalgia.

A 37-year-old woman was examined because of temporary diarrhoea. On CT scan, there was an abnormality of the liver. MRI showed a tumour that was suspicious for adenoma. Biopsy confirmed the diagnosis of hepatocellular adenoma. The patient then discontinued the use of oral contraceptives. The tumour regressed and was resected after two years. A 22-year-old woman presented with abdominal pain. A tumour was found in the upper right quadrant of the abdomen. In the laboratory, liver function tests were abnormal. Ultrasound and a CT scan of the liver showed an adenoma. After withdrawal of oral contraceptives, abdominal complaints lessened, but no regression of the tumour was detected. Surgical resection was uncomplicated. Hepatocellular adenoma is a rare, benign tumour of the liver, most often seen in young healthy women. Its incidence is rising due to the prolonged use of oral contraceptives. Not rarely, benign liver tumours are incidental findings on echography. If symptomatic, the presentation usually consists of vague abdominal complaints. Spontaneous rupture and malignant degeneration have been reported for adenoma. A reliable diagnosis is mandatory for the decision whether to apply surgery or continue observation. Radiological investigations play a key role in the detection and diagnosis of hepatocellular adenoma. Due to the risk of bleeding and malignant degeneration, elective surgical resection is indicated in symptomatic adenomas, asymptomatic adenomas larger than 5 cm in diameter, and smaller adenomas without regression after discontinuation of oral contraceptives.

A 75-year-old man had been admitted to another hospital because of left abdominal pain, and was given a diagnosis of left hydronephrosis and acute pancreatitis. After a JJ stent insertion and medication, he was transferred to our hospital for further examinations. US and EUS revealed a chronic pancreatitis-like pattern and multicystic lesion in the pancreas head and body. At that time enhanced CT findings showed an extrapancreatic low density area to be inflammatory change, extending from the pancreas body to the left crus of the diaphragm and posteriorly the spreading from the left crus of the diaphragm via the left urinary duct into the left iliopsoas muscle, in which MRI revealed partial high intensity. ERCP and MRCP showed focal irregular narrowing of the pancreatic duct of unknown cause, and we decided that an internal pancreatic fistula due to pancreatitis had induced left ureteral obstruction, caused by a protein plug or alcohol. Follow-up 6 months later showed that extrapancreatic spreading of the low density area had markedly regressed without any change in the ureteral obstruction.

The diagnosis and treatment of patients with pancreatic strictures presents a multitude of clinical challenges. The etiology of pancreatic strictures is varied, including benign strictures subsequent to acute pancreatitis, trauma, postsurgical, post-endoscopic retrograde cholangiopancreatography (ERCP), and malignancy. Patients with strictures usually present with symptoms of recurrent pancreatitis, abdominal pain, weight loss, and/or steatorrhea. The absence of a prior history of pancreatitis or surgery increases the likelihood of malignancy. High-quality imaging studies of the pancreas, CT, MRI/magnetic resonance cholangiopancreatography, or endoscopic ultrasound (EUS) scanning are utilized for better definition. Imaging detects an associated mass and/or demonstrates the ductal anatomy. Invasive procedures such as ERCP are performed to better define the causal relationships of the patient's symptoms or to obtain tissue diagnosis. Treatment goals include ameliorating symptoms, dilating the stricture, and ruling out cancer. The risk of malignancy underlies much of the intervention, which includes serology, cytologic analysis, and serial imaging. EUS has become the procedure of choice to rule out a mass, to evaluate the parenchyma for evidence of chronic pancreatitis, and to obtain fine-needle biopsies for tissue confirmation. In symptomatic patients or patients with indeterminate strictures, ERCP is used for direct pancreatography, tissue acquisition, and endoscopic treatment. Endotherapy includes sphincterotomy, dilation, and stenting to provide drainage. We view ERCP as the optimal first-line treatment modality. ERCP offers the potential of curative treatment and is less invasive than surgery, especially as some patients' symptoms are not severe enough to justify surgery. If patients do not experience relief of symptoms after several sessions of endoscopic therapy, surgery is the logical next step for definitive, long-term treatment.

An 83-year-old woman was admitted to hospital with complaints of fever, abdominal pain and other complaints suggesting urosepsis. Additional analyses did not reveal the cause of her complaints. After cessation of antibiotic therapy, there was a spontaneous decrease in the infection parameters and she was subsequently discharged. Two and a half months later she was presented in our hospital with low back pain with radiating to the legs. MRI showed signs ofa spondylodiscitis at the level of LIII-LIV existing for some time. Finally, a gram-positive streptococcus infection was found and she was treated with antibiotics for 13 weeks. 6 months later she was free of symptoms. A 57-year-old man was admitted to the intensive care with a double-sided olecranon bursitis and sepsis. An endocarditis caused by Staphylococcus aureus was thought to be the cause of the sepsis and the patient was treated with surgical intervention and antibiotics. Because of persistent sepsis, different CT-scans were performed, and after one and a half months an extensive spondylodiscitis with abscess formation was diagnosed and subsequently treated surgically. A delay in diagnosing spondylodiscitis is the rule rather the exception. The diagnosis should be considered in any patient with localised back pain, especially when accompanied by fever, high ESR, and the presence of risk factors such as high age, diabetes mellitus, immunosuppression, and/or rheumatoid arthritis.

Littoral-cell angioma (LCA) is a primary splenic vascular tumor that arises from the normal littoral cells lining the sinus channels of the splenic red pulp. We report a case of LCA of the spleen, which has been infrequently communicated in the literature. A 76-year-old man with a 2-wk history of weight loss, abdominal pain and changes in bowel habits was admitted to our hospital. Imaging studies (CT and MRI) showed multiple lesions in the spleen. Splenectomy was performed. Lining cells were positive for CD31/CD68 markers. Our case was associated with a serrated colonic adenoma. LCA is a benign vascular tumor of the spleen that needs to be included in the differential diagnosis of multiple splenic nodules.

A 13-year-old unmarried female presented with severe colicky lower abdominal pain, radiating to left side, not associated with fever. Ultrasound examination showed a dilated left fallopian tube with minimal free fluid in pelvis, and diagnosis of pelvic inflammatory disease was suggested. MRI of the pelvis showed a complex intensity mass in left adnexa, suggesting a germ cell tumour. Patient underwent diagnostic laparoscopy and laparoscopic removal of left fallopian tube. Histopathology finally established the diagnosis of left fallopian tube torsion.

A 22-year-old woman was treated for a hepatic lesion with a high suspicion of a liver adenoma at another hospital. The patient presented with unspecific abdominal pain. Further physical examination was unremarkable. A biopsy of the liver lesion revealed hepatic adenoma. Because of the increasing tumour size over a one-year period the patient was referred to our department for surgical therapy. On MRI scan, the liver mass measured 10 x 9 x 9 cm in the right liver lobe with contact to the right hilum. Because of the histological signs of adenoma a right hepatic lobectomy was performed. Postoperative follow-up was uneventful. The pathological diagnosis of hepatic angiomyolipoma was obtained. Angiomyolipoma of the liver is a rare benign mesenchymal tumour often mimicking other hepatic lesions. Histological features are thick-walled blood vessels, mature fat and smooth muscle in various proportions. The biological behaviour of the tumour is benign, although distant metastases are occasionally possible. Due to the potential for malignant transformation, tumour resection should be performed.
