Antepartum cases of ovarian vein thrombosis are extremely rare and often misdiagnosed. A 22-year-old nullipara at 29 weeks' gestation presented with right lower quadrant pain and fever. Sonography revealed a tubular, hypoechoic mass. At laparotomy, a noninflamed appendix was found and a 2 x 4 cm retroperitoneal mass was palpated near the right ureter. Postoperative magnetic resonance imaging (MRI) revealed bilateral thrombosis of the ovarian veins with caval extension. Therapeutic anticoagulation was achieved, but the patient underwent cesarean delivery 4 days later due to active labor and malpresentation. Postoperative MRI showed no extension of the thrombi, and her postpartum course was otherwise unremarkable. MRI is a valuable, noninvasive tool in the diagnosis of venous thrombi in pregnancy.

Appendicolithiasis is a condition characterized by a concretion in the vermiform appendix. Appendicoliths are found in 10% of patients with acute appendicitis, but they are seen more frequently in perforated appendicitis and in abscess formation. We herein report a case of acute appendicitis due to appendicolithiasis, which mimics acute disorders of the genitourinary tract and causes diagnostic confusion. A38- year-old man presented to our emergency department with a history of intense, acute, recurrent, crampy right lower quadrant pain radiating to the right groin region, accompanied by nausea. Physical examination revealed muscular defense and rebound tenderness in the right lower quadrant, tenderness in the line of the right ureter and right costovertebral angle tenderness. On X-ray examination, a right kidney stone was identified as was an incidental 3-cm density in the right lower quadrant. The patient underwent appendectomy. The diagnosis was made by operation and also X-ray examination of the appendectomy material showing appendicolithiasis. Acute appendicitis may manifest as a variety of genitourinary disorders. The possibility of an appendicolith with or without acute appendicitis must always be considered in the differential diagnosis of acute lower abdominal and pelvic disorders, and in the consideration of common acute urological disorders.

The differential diagnosis of right lower quadrant abdominal pain includes both ureterolithiasis and acute appendicitis. Surgical treatment can be undergone without confirmatory imaging studies after a clinical diagnosis is made. For this reason, an occult, second abdominal process may be present. A 47-year-old male presented with a three-day history of acute right lower quadrant abdominal pain. A contrast CT revealed both a 6 mm calculus obstructing the right ureter and acute appendicitis. The patient underwent appendectomy and ureteroscopy with stent placement at the same time. Simultaneous appendicitis and ureterolithiasis may present with similar clinical findings. Due to the potential risks associated with missing either diagnosis, imaging studies may be an appropriate as a step in the management of the patient with right lower quadrant pain.
