Lamivudine is widely used for the treatment of chronic hepatitis B infection because of it's remarkable antiviral efficacy and safety. We report a case of severe skin eruption caused by lamivudine. A 47-year-old female was admitted because of jaundice and itching sensation. She was diagnosed as chronic hepatitis B infection a few years ago but did not receive any specific treatment. Laboratory data showed acute deterioration of chronic hepatitis B infection. We prescribed lamivudine as a rescue therapy. Her general condition improved and lab data showed improvement in liver function test thereafter. However, she complained of severe skin eruption and itching sensation a few days after the discharge. We stopped lamivudine because the symptoms did not improve despite the use of anti-histamine. Skin biopsy showed interface dermatitis. After stopping lamivudine, her symptoms improved. However, the skin eruption developed again after lamivudine was restarted. Adefovir was used instead, and the patient did not experience any further skin problems since then.

Acute pancreatitis and afferent loop syndrome (ALS) have similar symptoms and physical findings. Accurate early diagnosis is essential, as the management of acute pancreatitis is predominantly conservative whereas ALS usually requires surgery. We experienced one case of pancreatitis due to ALS with internal hernia. Laboratory findings of patient showed elevated serum amylase, lipase and WBC count. One day after admission, diagnosis was modified as acute pancreatitis caused by ALS on computed tomography. Patient was managed with surgical treatment and operation finding revealed ALS due to internal hernia. He was recovered well after surgical treatment and discharged without significant sequelae.

Iliopsoas abscess (IPA) is rare in neonates. We present a case of neonatal IPA that was initially believed to bean inguinal hernia. A 20-day-old male infant was referred to our hospital for herniorrhaphy after a 2-day history of swelling and bluish discoloration of the left inguinal area and leg without limitation of motion. Abdominal and pelvic ultrasonography suggested a femoral hernia, but the anatomy was unclear. Abdominal computed tomography revealed a multi-septated cystic mass extending into the psoas muscle from the lower pole of the left kidney to the femur neck. Broad spectrum antibiotics were initiated, and prompt surgical exploration was planned. After opening the retroperitoneal cavity via an inguinal incision, an IPA was diagnosed and surgically drained. Culture of the abscess fluid detected Staphylococcus aureus, sensitive to methicillin. The patient was discharged without complication on the 17th postoperative day.

A 70-year-old man with past history of hemicolectomy due to colon cancer underwent a follow-up abdominal/pelvic CT scan. CT revealed a right adrenal metastasis and then he underwent FDG-PET/CT study to search for other possible tumor recurrence. In PET images, other than right adrenal gland, there was an unexpected intense FDG uptake at right inguinal region and at first, it was considered to be an inguinal metastasis. However, correlation of PET images to concurrent CT data revealed it to be a bladder herniation. This case provides an example that analysis of PET images without corresponding CT images can lead to an insufficient interpretation or false positive diagnosis. Hence, radiologists should be aware of the importance of a combined analysis of PET and CT data in the interpretation of integrated PET/CT and rare but intriguing conditions, such as bladder herniation, during the evaluation of PET scans in colon cancer patients.
