Castleman's Disease in Neck

Castleman's disease is a rare disorder that is characterized by lymphoid hyperplasia. It may present as an asymptomatic involvement of one lymph node group or as a multicentric disease with systemic features. Here we report a 53 year old female patient with histopathologically proven cervical Castleman's disease of the mixed type who presented with neck lymphadenopathy and was treated with a complete excision of the neck mass without complications.

Expanding Hematoma of the Abdominal Wall Caused by Spontaneous Rupture of a Deep Circumflex Iliac Artery:Report of A Case Treated by Coil Embolization

Abdominal wall hematoma is a rare but well-known disease, usually caused by trauma or, on rare occasions, occurring spontaneously. Hematomas of the rectus sheath and the anterolateral abdominal wall are commonly associated with injury to the inferior epigastric artery and the deep circumflex iliac artery, respectively. The diagnosis of spontaneously developed abdominal wall hematoma is sometimes delayed, due its clinical manifestations being similar to those of other causes of the acute abdomen. CT and angiography can be helpful in the diagnosis of the hematoma and the injured vessel. Herein, we report on a rare case of a spontaneously developed anterolateral abdominal wall hematoma treated with microcoil embolization of the left deep circumflex iliac artery.

Percutaneous Ethanol Ablation of Hepatic and Renal Cyst: Therapeutic Effect and Follow-Up Study

PURPOSE: To evaluate the ability of percutaneous ethanol ablation in the treatment of benign cysts of the liver and kidney, and to decide the need and the time of retreatment when the cysts remain on the follow-up ultrasonogram. MATERIALS AND METHODS: Twenty benign cysts(8 hepatic and 12 renal cysts) in 18 patients diagnosed or confirmed either by ultrasound, CT or cytology were treated with percutaneous ethanol injection(PEI). After evacuation of cystic fluid, 15-900ml(amount corresponding to 40-50% of the volume of aspirated fluid) of absolute ethanol(99.9%) was injected into the cysts through the aspiration catheter. rln large cysts, two or more PEIs were done in one session. Follow-up ultrasonographic studies during the period of 12 months with 1-2 months interval after PEI were performed for evaluation of the therapeutic effect. RESULTS: Nine cysts(45%) disappeared completely within 2 months after initial PEI. Although 11 cysts(55.5%) recurred 2 months after initial PEI, 8 of them disappeared within 6 months and one within 8 months after inital PEI without additional PEI. As a result, 18 of 20 cysts(90%) disappeared within 8 months after initial PEI and most of the recurrent cysts disappeared within 6 months without additional PEI. No major complications were encountered concerning PEI, although transient abdominal pain, elevation of body temperature, and drowsiness were noted in 8 patients. CONCLUSION: PEI is an effective and safe modality for the treatment of benign hepatic or renal cysts and the apparent recurrence within 6 months after initial PEI might be mostly a transient, reactive or inflammatory fluid collection rather than real recurrence.
