We describe the case of a pediatric patient with acquired immunodeficiency syndrome (AIDS) with an unusual large, fluid-filled intra-abdominal cystic lesion in which Pneumocystis carinii trophozoites were identified. Extrapulmonary P. carinii infection should be considered in the differential diagnosis of an intra-abdominal cystic mass in a child with AIDS.

Abdominal wall endometriosis is a rare condition, which usually develops in a surgical scar of abdominal hysterectomy or Caesarean section. A 38-year-old lady presented in the surgical out patient department complaining of painful swelling in the lower abdomen, at the left edge of the scar of caesarean section. Computerized tomographic (CT) scanning of the pelvis with contrast revealed an enhan...

A 62-year-old man presented to the emergency department with sustained left-sided abdominal pain. An examination revealed abdominal tenderness localized the left paraumbilical region. Ultrasonography showed an oval, noncompressible lesion with heterogeneous echotexture located at the point of tenderness (Picture 1). Abdominal computed tomography revealed an oval-shaped fat-dense lesion with a t...

Mesenchymal hamartoma of the liver (MHL) is a benign and rare hepatic lesion, with an uncertain etiology and a potential for developing into an undifferentiated distant embryonal sarcoma after an incomplete resection. It mainly presents as progressive abdominal distension with normal blood works. Most cases are diagnosed in the first two years of life, with a higher frequency in boys and on the...

OBJECTIVE To describe a case of adrenal cavernous hemangioma in a 67 year old man who presented left lumbar pain. METHODS Abdominal ultrasound, contrast enhanced ultrasound of the lesion, abdominal-pelvic CT scan, and then left adrenalectomy and pathology were performed RESULTS Imaging studies showed a large solid-cystic mass with 12 × 11 cm diameters in the left adrenal gland, well defined...

Intra-abdominal cysts and pseudocysts are rarely occurring lesions. Their incidence is reported to be 1 per 100 000-250 000 hospitalizations. The lesions' rarity and their mostly asymptomatic development causes troubles in early recognition and treatment. The patients' complaints are unspecific and mostly occur when the cysts are enlarged. Sometimes these entities may cause signs of peritoneal ...

Esophageal duplication cysts are congenital anomalies of the foregut that are rarely found in the abdomen. An accurate preoperative diagnosis is not always possible, so the definitive diagnosis can be made by histologic examination of the surgical specimen. We experienced a case of Intra-abdominal esophageal duplication cyst in a 52-year-old female, who initially presented with an esophageal su...

A 53-year old man was admitted with painless progressive abdominal distension of 1 year duration. He was a lorry driver and his abdomen started touching the steering wheel, making his job difficult. The abdominal distension was increasing despite treatment for “presumed” ascites. Clinical examination revealed a symmetrically distended abdomen with no palpable masses (Figure1). The swelling was ...

BACKGROUND An abdominoscrotal hydrocele (ASH) is a rare lesion and should be considered in the differential diagnosis of abdominal cystic lesions in boys. CASE REPORT We report a case of a 4-month-old boy with a thin-walled, anechoic cystic abdominal mass in ultrasound (US) examination. As the size of the lesion increased in follow-up US after one month, computed tomography (CT) was performed...

Gastrointestinal stromal tumours (GISTs) are solid tumours of the gastrointestinal tract, mostly found in the stomach and intestine. They rarely present as cystic lesions. A 74-year-old woman referred to the hepatopancreaticobiliary unit, with 3 months history of upper abdominal discomfort. Abdominal ultrasound scan showed a large cystic lesion in the epigastric region suggestive of a pancreati...
