Overview
Ascariasis can mimic other worm infections, and also gastrointestinal pathologies like peptic ulcer disease, intussusception in children, bile duct stone, etc.[1][2]
Differential Diagnosis
- Differential diagnosis of intestinal ascariasis
- Peptic ulcer disease[1]
- Intestinal obstruction from Ascaris lumbricoides can mimic intussusception[3]
- Differential diagnosis of biliary ascariasis
- Gallbladder cancer[4]
- Retained bile duct stone[2]
- Other worm infections can sometimes have clinical presentations similar to that of Ascaris lumbricoides
The table below summarizes the findings that differentiate ascariasis from other nematode infections:
| Differentiating ascariasis from other Nematode infections[5][6][7] | ||||||
|---|---|---|---|---|---|---|
| Nematode | Transmission | Direct Person-Person Transmission | Duration of Infection | Pulmonary Manifestation | Location of Adult worm(s) | Treatment |
| Ascaris lumbricoides | Ingestion of infective ova | No | 1-2 years |
|
Free air in the lumen of the small bowel
(primarily jejunum) |
|
| Strongyloides stercoralis | Filariform larvae penetrate skin or bowel mucosa | Yes |
|
|
Embedded in the mucosa of the duodenum, jejunum | |
| Trichuris trichiura
(whipworm) |
Ingestion of infective ova | No | 1-3 years |
|
Anchored in the superficial mucosa of cecum and colon | |
| Hookworm | Skin penetration by filariform larvae | No |
|
|
Attached to the mucosa of mid-upper portion of the small bowel | |
| Enterobius vermicularis
(pinworm) |
Ingestion of infective ova | Yes |
|
|
Free air in the lumen of cecum, appendix, adjacent colon | |
