A case of urachal remnant presenting as acute abdominal pain

Paediatric urachal benign teratoma: a case report and review of the literature

Urachal anomalies are most often seen in children, seldom in adults, but are in general considered rare. The estimated incidence is one in 5000-7000 live births and appears twice as common in males. Despite their rarity, they need to be considered by clinicians, as diseases in the urachus can mimic many abdominal and pelvic conditions and constitute an important differential diagnosis to these. Diagnosis can be made by clinical examination and imaging modalities (computed tomography, ultrasonography, magnetic resonance imaging, voiding cystourethrogram), but some are discovered incidentally. Management of symptomatic urachal anomalies is surgery. Histological examination of the specimen should always be performed to rule out malignancy. We report on the first adolescent described in the literature diagnosed with a urachal sinus harboring a benign teratoma. A combination of the two pathologies is by inference an extremely rare condition, which we here report on and we review the relevant literature on this topic.

Red Umbilicus as a Clinical Manifestation in a 19-Month-Old Girl with Typhoid Colonic Perforation

Redness of the umbilicus is usually considered to be a reliable sign of underlying gangrenous bowel or peritonitis in tiny infants but seldom among non-neonatal patients. We report a 19-month-old girl with final diagnosis of typhoid colonic perforation who initially presented with abdominal distention and umbilical erythema on arrival at our emergency department. The redness of umbilicus diminished gradually after laparotomy. Thin abdominal wall, severe intra-abdominal soiling, and polymicrobial infection accounted for the inflammatory process spreading to the skin of the umbilicus. Because of its rarity beyond the neonatal period, prompt diagnosis depends on maintaining a high index of suspicion when the abdomen is distended and suddenly tender to palpation.

Acute presentation of infected urachal cysts: case report and review of diagnosis and therapeutic interventions

Urachal remnants, although relatively rare, masquerade as a large number of diverse disorders leading to a high rate of misdiagnosis. A typical case is reported in which a 10-year-old boy presented to the Emergency Department twice before being incorrectly diagnosed with a pelvic or lower abdominal periappendiceal abscess. Definitive diagnosis and treatment of an infected urachal cyst were made intraoperatively. A review and discussion of urachal remnants is presented, and a diagnostic algorithm and treatment plan is offered for this entity.

Inflamed urachal cyst containing calculi in an adult

The urachus is an embryonic structure that persists after birth in some individuals and can cause various problems. We report a case of an inflamed urachal cyst filled with a thick yellow fluid and several calculi in a woman with a 1-month history of dysuria. Physical examination revealed a fist-sized tumor located infraumbically in the midline. The patient's erythrocyte sedimentation rate was elevated; the results of all other routine laboratory studies were normal. Sonography showed a regularly shaped, ovoid, hypoechoic cystic area in the abdominal wall measuring 8 x 4 x 3 cm and containing several hyperechoic masses associated with acoustic shadowing. The wall of the cyst was inhomogeneous, and a thin hypoechoic linear tract linked the superior aspect of the mass to the umbilicus. The results of excretory urography, voiding cystography, and cystoscopy excluded an abnormality of the urinary system. A urachal cyst was diagnosed, and the mass was surgically removed. The surgical specimen was sent for histopathologic analysis, which confirmed the diagnosis.
