Diagnosis can be challenging pre-opertaively, as patients are commonly asymptomatic. Physical examination can aid in diagnosis if the mass is palpated, but further confirmatory tests are necessary. Females are reportedly less affected by<unk> , though it is possible that the condition is underdiagnosed due to the difficulty of internal gonad examination in females. On scrotal ultrasound, ectopic splenic tissue may appear as an encapsulated homogenous extratesticular mass, isoechoic with the normal testis. Subtle hypoechoic nodules may be present in the mass. Limitations of doppler ultrasonography include visualizing the nonspecific paratesticular masses which can mimic malignancies such as rhabdomyosarcoma or embryonal sarcoma. Technetium-99m sulfur colloid scan is sensitive to target the liver, spleen, and bone marrow, therefore the scans can be used to identify ectopic splenic tissue when clinical suspicion is high. When technetium-99m sulfur colloid scans are not included in a patient's diagnostic workup, the diagnosis is often not made until the surgeon performs an abdominal exploration using laparoscopy which can visualize the splenic tissue grossly. Evaluation by biopsy including frozen section procedure is confirmatory for<unk> . Histological examination will show normal splenic tissue which is made up of red and white pulp. Many people with<unk>  go undiagnosed without complication during their lifetime. Many cases have been diagnosed at autopsy or incidentally after orchiectomy.
